Transformer:Magnetic Transformer, Wattage:600 Watt Maximum This remote transformer converts standard 120 volt line voltage to 12 volts, providing the necessary voltage for powering a low-voltage lighting system. Can be used to power lamps totaling up to 150, 300, or 600 (two runs of 300) watts. Equipped with fast-acting secondary circuit breaker that will safely turn off the system should a short occur. Once the short has been removed the breaker can be reset. Should be installed in an accessible location above the ceiling or in a closet. To simplify installation the transformer should be located no more than 20 feet from the run or power feed. 100 and 300 watt transformers are dimmable with a 600 watt low-voltage dimmer and must be used with a single-feed canopy or other power feed option (sold separately). 600 watt transformer is dimmable with a 1000 watt low-voltage dimmer must be used with a dual-feed canopy or two other power feed option (sold sep
