The G Range BM Series switch mode power supplies are ideal for applications requiring mains and battery monitoring. The units have a regulated highly stable output supplying full rated current to load and a universal mains voltage input range (90 to 264V ac). These units may be used for intruder systems where compliance with EN50131-6 is not required. They are also available in DIN rail mounted ‘unboxed’ versions if required. FOM 4 or 8 can be fitted to give independent fused outputs.
