About our 300 Watt - 12 Volt - Hardwire - Electronic Transformer - Enclosed - Ground Wire - Lightech

This 300-watt low voltage enclosed electronic 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 AC lighting systems.
  • Maximum 300 Watts of Load: 300 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, 60 Hz, 2.5 amps
  • Input Leads: one 6-inch 18 AWG white wire (neutral) and one 6-inch 18 AWG black wire (hot)
  • Output: 11.7 volts AC, 25.5 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 6-inch 12 AWG blue 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 12 AWG.]
  • Ground Lead: one 6-inch 18 AWG green wire
  • Steel Enclosure: outside enclosure around transformer is made of steel, perfect for storing electrical connections; inside casing of transformer is made of aluminum
  • Installation: the transformer and all of the hardwired electrical splices (connections) can be stored in the included metal enclosure
  • Dimensions: 1-7/16in(H) x 1-5/8in(W) x 9-3/8in(L)
  • Weight: 1.48 lbs
  • 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.]

I would recommend this item to a friend.

As expected
February 24, 2012
Unit is installed and operating properly. Only been in use for a week so longevity cannot be attested to. Knock-outs for wiring were a little difficult to remove without bending the case. Case metal could have been a little stronger. But ... working as expected & arrived promptly.
Working as expected
Metal case a little cheap
