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!

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.

Dropped right in and worked perfectly

This transformer was a replacement for an under-counter light that started intermittently turning off and on. It dropped right in (smaller than the original) and is working perfectly.

Excellent Kichler Transformer Replacement
February 13, 2014
Like many others, I have a Kichler Under Cabinet light that failed. This transformer is an easy swap out for the original and worked like a charm. I will probably get some spares.
Easy to Install Price (compared to replacing the entire Kichler light ($100+) It works.

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.

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.

Our drivers are on this page:

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.

By Dave from Pa. on November 26, 2013
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 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 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).
