The UPS module (online DC-UPS) supplements the 24 V DC 10 A power supply and provides an uninterruptible 24 V DC supply for the Ackermann nurse call system. During a power failure the module takes over from the battery; with mains voltage present the system is supplied by the power supply and the battery is charged. Power failures and faults are reported according to DIN VDE 0834-1. The UPS module is mounted on a DIN rail and the battery on the wall of the sub-distribution board; for maximum uptime replace the battery every 4 years.
