Redundant Power Supply

Redundant Power Supply for RTV-1124

The RPS-1124 power supply and battery charger is a 4U 19" aluminium frame; it can host two PWS-1124 power supply modules and one BCU-1124 battery charger module. It is especially suited for use where redundant power supply is required, since each module can be hot-swapped without interrupting power output. The RPS-1124 features a connector for mains power input (VAC Line), a power connector for DC power output (VDC OUT), and a power connector for battery connection (Battery).
The BCU-1124 module is a microprocessor-controlled battery charger; it can:
  • charge 24 V lead-acid batteries up to 200 A
  • check battery charging status and end of charging
  • check for possible overloading
  • manage discharging, disconnecting battery load if the battery voltage drops below a threshold, in order to avoid damage to batteries due to excessive discharging.
The PWS-1124 module transforms the mains voltage (220 V ac) into dc voltage (30 V dc nominal).
