Back up power supply unit (BPSU) is designed for:
BPSU is based on uninterruptible power supplies (UPS), which perform the following functions:
BPSU may comprise one or two UPS, each of which is connected to a set consisting of eight batteries.
Constituent parts of BPSU (including off-hand batteries) are installed in a cabinet of the floor mounted version with the opening door for convenience of mounting and working.
