About our 150 Watt - 12 Volt - Hardwire - Electronic Transformer - Enclosed - WAC Lighting

This 150-watt electronic enclosed low voltage transformer will power your 12-volt lighting systems. With an enclosed transformer, you can store all of the electrical connections in the included metal enclosure, meaning a separate junction box is not required. Electronic transformers are generally smaller, lighter, quieter, and cooler than magnetic transformers.

  • Uses: used to power 12-volt AC lighting systems.
  • Maximum 150 Watts of Load: 150 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 50 Watts of Load: unless this transformer is powering at least 50 watts of lighting load it will not work properly
  • Input: 120 volts AC, 50/60 Hz, 1.25 amps
  • Output: 12 volts AC [Caution: a standard AC voltmeter cannot measure the output of a high frequency electronic transformer; instead, a special "true RMS" voltmeter must be used.]
  • Installation: the transformer and all of the hardwired electrical splices (connections) can be conveniently stored in the included metal enclosure
  • Dimensions: 1-5/8in(H) x 3in(W) x 6-1/4in(L)
  • 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.]

Questions & Answers
By Robert Cone from Bend, OR on January 19, 2015
This transformer is located within my garage and hard wired to a switch inside my house. How can I add a photo switch to turn on/off at dusk/dawn?

By Jacob from Pegasus Lighting on January 19, 2015

Robert, I would suggest consulting an electrician. Since it's inside your garage, a photocell cannot simply be attached to the transformer because it won't be able to detect the outdoor brightness.

You may find that your best bet is to install a timer instead of the wall switch. You can set the timer to turn the lights on/off at certain times of the day.

By Al Goodridge from New York on July 29, 2012
I have seven 20-watt under the cabinet puck type lights. At present time I have a EN-B12 PY-AR 100-watt minimum to 250w maximum. Can I replace the one that I have with the 150-watt? I have had the transformer for over 8 years. I think it is starting to go because the lights are flickering. All connections are tight. I am only using 140 watts.
By Chris at Pegasus Lighting on July 30, 2012


This electronic transformer has a 50-watt minimum and a 150-watt maximum load and, unlike a magnetic, this electronic transformer can be used up to its maximum wattage. So, since you are powering 140 watts this electronic transformer will work for your situation.
