Designed to power 12V low voltage fans installed in the splash area of the shower or bath, the T12 series of Safety Extra Low Voltage (SELV) transformers can be mounted in the loft area (not Pullcord, Humidistat or PIR models) or high-up on the ceiling next to the pullcord light switch. There are 14 models in the range, all fitted with a neon light and complete with pattress. The units are manufactured using impact resistant, high gloss ABS thermoplastics for strength, durability and easy cleaning.
