SBPS – Standby Power Supply

The SBPS / 2.5 module in conjunction with the BP / 2.5 module is an intelligent Mini USV designed for power supply with 24V including 4 fused outputs and 2 inputs for external, constantly rechargeable NiMH battery packs. With the help of two redundant RS422 inputs, serial telegrams may be processed, e.g. for time synchronisation with the internal RTC or for power management tasks such as limitation of battery life, alarm analysis or final self-shut down when the minimum discharge threshold of the battery packs has been reached. The output of alarm telegrams and the ZDA telegram is carried out through an RS422 interface with up to 115200bps. The overall system can be completely switched on and off through a key switch.
