1. Technical description.
1.1. General description.
The PSU is intended for 230V AC mains supply to devices that require stabilised voltage of
7,5V DC.
The PSU can be
assembled in installation boxes, surface or flush-mounted, or fitted with 3mm screws. The unit is protected against a short circuit
and an overload and a surge.
