UL & cUL listed electronic transformer is the perfect solution for wiring multiple low voltage fixtures. WAC transformers are intrinsically safer transformers because they are compartmentalized to allow no greater than 5 amps of current to be drawn on each compartment. Secondary wiring for transformers do not require conduit sheathed cable or clamp wiring techniques. This transformer has a low minimum load requirement of 1W to allow the use of LED products. May be dimmed using an electronic low voltage dimmer.
