VARILIGHT^® Dimmable Transformers

VARILIGHT® transformers provide a trouble-free solution when used with our dimmer switches to dim low voltage lighting. Read Instruction Leaflet

They are the preferred choice for many electricians whether or not they are to be dimmed. They can be loaded from zero watts to their maximum rating making them ideal for use as a power source for 12V a.c. LED lighting. The key features of VARILIGHT transformers are:-

• Short circuit survival
• Auto-resetting overload and over-temperature protection
• Soft start for extended lamp life
• Any loading up to the maximum will work. Can be loaded from 0 (ie. total lamp failure) to its maximum rating
• Dim up to full rating of dimmer with several transformers in parallel per VARILIGHT dimmer module (only 5 when other brands of transformer are used)
