12V Switch Mode PSU(13.8V)3Amp to load + 0.5A battery charging

The G Range BM Series switch-mode power supplies are ideal for applications requiring mains and battery monitoring, providing a regulated, highly stable 13.8V DC output with full rated current to the load. These units feature a universal mains input range (90–264V AC) and are suitable for intruder systems where compliance with EN50131-6 is not required.

DIN rail-mounted “unboxed” versions are available, and optional FOM4 or FOM8 modules can be fitted to provide independent fused outputs.
