Uninterruptible Power Supply Device 1 (PBP1) for Reliable 28.5V DC Power Supply

PBP1 is designed for uninterrupted power supply of consumers on twelve independent galvanically isolated channels with voltage of DC 28, 5 V from DC network 175-320 V or from AC network 220 V at operation under severe conditions of mechanical and climatic influences, in unattended premises with remote access. Uninterrupted power supply in the absence of mains voltage for more than 0.08 s must be ensured by an external network switch. PBP1 modules provide remote signalling via compacted communication lines (redundant Ethernet network).

Electrical parameters of output channels 1-12 correspond to the values specified in the table. The PBP1 is a two-storey instrument rack with modules installed in it. Connectors for the input power supply network and Ethernet networks are located on the side surface of the module MZ F.

Output connectors are located on the side surface of the rack. The weight at...
