FAQ

Yes, if your current unit has the model number 7693W, this is a like-for-like replacement. Always verify the part number and electrical specifications of your old unit before installation.

The T2AL is a 2 Amp, slow-blow (time-delay) fuse that protects the power supply and the connected BUS system from overcurrent situations. It is located on the internal PCB and is user-replaceable, provided the unit is disconnected from mains power first.

This power supply is specifically designed with the voltage and current characteristics required by the Legrand SCS BUS. Using it for other applications is not recommended as the high DC voltage (145V) may not be compatible with other devices and could cause damage.
