Designed to power 12V 100mm & 120mm 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.
T12 25 watt transformer models are for use with 100mm & 125mm low voltage fan range such as PEFLVF, XF100LV, XF100HTLVT - WF100LV - XF120LV & WF120LV.
These appliances are double insulated and do not require an earth but must be connected to the supply through a suitable double pole isolating switch with a minimum contact gap of 3mm on fixed wiring circuits. The protective fuse must not exceed 3A and installation must be supervised by a qualified electrician.
