About our 80 Watt - 12 Volt - Hardwire - Electronic Transformer - Hatch

This 80-watt low voltage transformer will power your 12-volt lighting systems. Electronic transformers are generally smaller, lighter, quieter, and cooler than magnetic transformers.

  • Uses: used to power 12-volt lighting systems.
  • Maximum 80 Watts of Load: 80 watts maximum of lighting load. Unlike most magnetic transformers, these electronic transformers can be used to power the maximum wattage. [Caution: Always attach the load to the transformer before connecting the transformer to power.]
  • Minimum 10 Watts of Load: unless this transformer is powering at least 10 watts of lighting load it will not work properly
  • Minimum 20 Watts with Dimming: when this transformer is connected to a dimmer, it must be powering at least 20 watts of lighting load or it will not work properly
  • Input: 120 volts AC, 50/60 Hz, 0.67 amps
  • Input Leads: one white 18 AWG wire (neutral) and one black 18 AWG wire (hot)
  • Output: 11.5 volts AC, 7.00 amps [Caution: a standard AC voltmeter cannot measure the output of a high frequency electronic transformer; instead, a special "true RMS" voltmeter must be used.]
  • Output Leads: two red 18 AWG wires [Suggestion: Use a terminal block for each connection in the 12V output circuit and make certain that these connections are very tight and secure. Also, be sure that the gauge of the electrical wire used in the output circuit is not less than 18 AWG.]
  • Installation: the transformer and all of the hardwired electrical splices (connections) should be stored in an enclosed metal junction box (not included)
  • Compact Size: only 0.75in(H) x 1.25in(W) x 2.2in(L)
  • Lightweight: only 2.4 oz
  • Dimmable: fully dimmable using a dimmer designed for an electronic transformer. An electronic transformer can sometimes work with a standard incandescent dimmer. However, to ensure that your lighting system works effectively with the greatest dimming range we recommend that you use a dimmer that was specifically designed to control an electronic low voltage transformer. Additionally, using this type of dimmer will diminish the possibility of an audible hum when the dimmer is used especially at low light levels. [Caution: dimmer should always be connected to the input side, 120V side, of a transformer.]
  • Short Circuit Protection: yes with auto-reset
  • Overload Protection: yes with auto-reset
  • Low Heat: low operating temperature
  • UL Recognized: UL recognized in USA and Canada
  • Brand: Hatch
  • 3-Year Warranty: this electronic low voltage transformer carries a 3-year warranty

Excellent product!!
October 20, 2013
I had an undercounter light go intermittent. Symptom appeared to be a bad (3 position) rocker switch. Internet research turned up bad transformers in the product. Ordered and installed this transformer and problem solved!!! Simple job (except getting TO the bad transformer). Actually, I ordered two transformers since we have six of these light fixtures. Probably should have bought four more!!

Perfect fix for Kichler K-10566 Xenon undercabinet light
July 31, 2013
I searched all over the internet for a replacement transformer for my Kichler fixtures. The manufacturer wouldn't sell a replacement, insisting that I had to buy another fixture instead. Nope. Didn't need to. I swapped out the old, defective transformers with this model and the lights are working once again. And best of all, these parts showed up within three days of the initial order. That's what I call prompt ordering fulfillment by Pegasus. Thanks for helping me complete this repair project in record time!

Good transformer
December 31, 2014
Replaced a 60 watt transformer that kept shutting off with this 80 watt transformer and haven't had any problems since. In fact I was able to go from 4 11watt bulbs to 4 18 watt bulbs. Super easy to hook up. Recommend it to be inside a junction box by itself.
Easy hook up

Easy to Install Transformer
October 27, 2014
I pulled four 10W under the cabinet lighting to this transformer. I understand it was overkill on what is required, BUT it provides me the capacity to double my lighting if needed in the future. For the price, cannot be beat!! I did install this into a junction box, but that was not an issue to its small size.

Kichler lighting replacement transformer
September 10, 2014
Best replacement for Kichler under cabinet lighting. Installed in 5 minutes. Double stick tape holds it in place. Just pry the old one out with a screwdriver, only held in place with silicone adhesive.

Questions & Answers
By David from Indianapolis on October 16, 2013
I am going to power 3 20watt bulbs - is it better to use an 80watt transformer than a 60watt? I assume you don't need to consider the load of the wiring when determining the transformer size, but is it better to partially load the transformer or size it to be fully loaded?
By Jacob from Pegasus Lighting on October 16, 2013


Electronic transformers can be fully loaded, so you are perfectly safe using a 60W electronic transformer.

With that being said, an 80W transformer would work just as well and allows you some freedom if you consider changing the wattage light bulb being used in the future.

By George J. from Rohnert Park CA. on June 16, 2013
I need replacement for my track lights which had converter for halogen lamps brand Anchorn not available anywhere, will Hatch electronic low voltage transformer 80 watt 12 volt fix the job?
By Jacob from Pegasus Lighting on June 17, 2013


If your track lights require 12V and if the total wattage does not exceed 80W, then this transformer should work for your system.

By Mike from NYC on February 23, 2013
Hi. I am building 3 soffits around my living room and wanted to install 14 x 2" recessed LED lights (each light is 5 watts for a total of 70 watts). The total length of the three soffits will be about 45 feet (15x15x15). Can I use this 80 watt electronic transformer for this project? The transformer would be about 10 feet from the light switch and then about 5 feet from the first of the 14 lights.

Would I be able to use this transformer for this project I should I look for another transformer?

By Jacob from Pegasus Lighting on February 25, 2013

Mike, LED lights typically require a driver NOT a transformer. First, I would verify exactly what type of power supply your fixtures need.

I have a 3 bulb Kichler under cabinet xenon light out as well only it's Model # K-10574-CLR. 18 watt 12.8 Volt. Will this item work?
By Jacob from Pegasus Lighting on November 10, 2014


If your transformer has failed then yes replacing it with this one should fix the issue.
By Gordon from Iowa on November 10, 2014

I have the same light. This transformer solved my problem light has worked great now.
By Tom from Cleveland, OH on November 10, 2014

This replacement transformer works perfectly. I have already replaced one and I now have a second fixture that is starting to flicker.

The most difficult part of the replacement was removing the old transformer. It is glued to the fixture with something like atomic elephant snot. I had to break it off in pieces. You can attach the new transformer with two sided foam tape.
By Chris from NC on November 10, 2014

I used them to replace the transformer in two of my under cabinet Kichler K-10566 lights (2 bulb Xenon), and they work great, fixed the intermittent lighting issue. Not sure about your exact model, but as the voltage is the same (12.8V) as mine, I imagine they are worth a try.
By David from Larchmont, NY on November 10, 2014

It worked for me.
By Nancy from Brook Park, Ohio on November 10, 2014

Hired a local electrician to repair and replace the transformer, was well worth the minimal fee. No bulbs were broken, light looks great once again.
Enjoy the beautiful under cabinet lighting!
By John from Texas on November 10, 2014

If the fixture has three lights total and each light is 18w = 54w total, the 80w 12V transformer will work.
By Dennis from Horseshoe Bay, TX on November 10, 2014

I replaced the bulbs, which didn't fix it, so I ordered the Hatch transformer and it works! It will handle up to 80 watts.
By Ed from Alpena, MI on November 10, 2014

It worked perfect for me. The wattage on my transformer is higher than your unit, but that's because my bulbs take more current since they are halogen, not xenon. I believe the transformer would simply not work as hard to light up your system. The voltage is right.
By Terry from US on November 10, 2014

Short answer is yes. It's an easy install. I purchased this unit myself for the very same Kichler unit and replaced the failed transformer. Works great again.
By Andy from Detroit on November 10, 2014

Yes, it works like a charm! I have replaced the transformer on two of my Kichler # K-10574-CLRs with this transformer without any issues after several months of use.
By David from NC on November 10, 2014

Yes, it worked just fine.
By Mack from Oklahoma City on November 10, 2014

I bought the transformer and replaced it on my under counter light. It worked for about 90 days and quit again, so I ordered a new under counter light and replaced the old one. It has been working for about 6 months. If it happened to another one of my lights I would just order a new light.
By Ed from Alpena, MI on November 10, 2014

It should work perfect - just like it did for me. The Hatch unit calls for a 10 watt min. draw with this particular transformer. Your system draws 18 watts. My system draws more because I have halogen bulbs. Kichler doesn't offer any parts to d.i.y. folks to service their under cabinet lights. So far, I'm completely satisfied.
By Claudia from Alanta on November 10, 2014

It worked great. The hardest part was opening the lighting unit.
By Frank Lozano from Houston, Texas on November 11, 2014

I originally thought I had a light bulb problem as several bulbs around the kitchen had gone out, so I ordered a dozen of them. After replacing the bulbs I had one section of lights that did not come one. After reading several different forums about how to fix it, instead of buying a new one, I found Pegasus Lighting. This item was EXACTLY what I needed. It was super simple to replace, although I was scared prying the old transformer from it's housing. Its only held on with double-sided sticky tape. After matching the wires to the old setup, putting all the screws back in place, I turned it on and it worked like new! I look like a master electrician to my wife. In fact, they are so inexpensive, I think I'll buy a few extras to have around the house just in case.
By Gary from Virginia on November 12, 2014

Mine was a Kichler 1058bz (3-light under cabinet light) and it has worked great.
By J from TX on November 12, 2014

As long as the total wattage of the bulbs in the fixture are less than 80 it will not be overloaded, as far as the 12V versus 12.8V that should not be a problem either. The output of the transformer can vary depending on the input voltage from the utility. If it is a little lower the bulb will not put our the rated lumens but I doubt that you can perceive the difference. It will not hurt anything. Good luck! Love the Kichler fixtures but the transformer has been a problem on 2 of them. Have not had any problem with the replacement transformer.

By Tony from San Diego, CA on June 1, 2014
My existing transformer has an output of 12.8V ~ >20KHz, 5Amps. Your transformer outputs 11.5 V, 7 amps. Will this transformer be a suitable replacement? If not, can you recommend an alternative with similar dimensions. It is for use with a Kichler K10566 fixture with 3 18W Xenon bulbs. Other people with my fixture seem to have had success with your transformer. The manufacturer will not supply a transformer, nor will they make recommendations for a replacement.
By Ila from Pegasus Lighting on June 2, 2014

Yes. This transformer is a suitable replacement.

Can this transformer be dimmed?
By Jacob from Pegasus Lighting on November 26, 2013

Absolutely! We recommend using a dimmer designed for an electronic low voltage transformer. Check out the Accessories section for this type of dimmer.

By Binh Nguyen from Milpitas, California on July 3, 2014
Can I use this to replace the SAT70 transformer which is specified at 110V, 60W?

By Ila from Pegasus Lighting on July 3, 2014

If your light fixtures require an electronic transformer, then the 80-watt transformer should be appropriate.

By Mike from Scottsdale on December 29, 2014
I have 6 incandescent low voltage lights mounted into my house walls that cast light on the deck. They are 11 watts each. Will this transformer be OK or can you recommend an appropriate one for mounting inside the house?
By Jacob from Pegasus Lighting on December 31, 2014

Mike, you need to determine the voltage needed by your lights. Is it 12V or 24V? If it's 12V, then yes, this will be fine.
By David Y from Maryland on December 31, 2014

As long as your fixtures and bulbs are for a 12 volt system you're good. You have 66 watts total so this 80 watt transformer is good. I have 4 18 watt bulbs on mine and works great. Hope that helps.

By George from Washington, DC on May 21, 2013
I need to replace a Hatch RL12-75a transformer. Will this work? What is the difference?
By Jacob from Pegasus Lighting on May 21, 2013


The major difference is that this transformer is rated for 80W and your older model is rated for 75W. That means the 80W can handle more power.

Other than that they are both 12V electronic transformers.

You shouldn't have any issues using this as a substitute.

By Finley Cosner from Napavine, WA on March 22, 2015
Will this work with 4 halogen 20 watt bulbs?
By Jacob from Pegasus Lighting on March 23, 2015

Yes, the max wattage for this transformer is 80W. Your four halogen bulbs will not exceed that max. Thanks!
By Richard from Silver Spring, MD on March 23, 2015

Worked fine with my 4 20 watt lamps.
By Keith from Morristown, NJ on March 23, 2015

Yes it will work as long as the total watts pulled from it doesn't exceed 80 total watts.
By Rene from Madison, AL on March 23, 2015

Short answer, yes. That said, I'm more of a belt and suspenders guy so I might look for a 100 W. Not strictly necessary though.

By Helen Kenney from Idaho Falls, Idaho on October 9, 2013
Will this transformer work in my Kichler brand undercabinet halogen lights? They are model #10563 and have worked intermittently depending upon their mood....
By Jacob from Pegasus Lighting on October 9, 2013


I believe your Kichler under cabinet lights are powered by integral transformers. As you can see in some of the reviews, other customers had success replacing the transformers in their Kichler under cabinet lights with this item.

I would recommend first contacting Kichler to see if you can replace the transformer without voiding the safety listings or even if they will warranty the product.

I would also make sure the dimensions will fit in the fixture - 0.75in(H) x 1.25in(W) x 2.2in(L).
