Safety power supply system with power limitation (LPS system, Low Safety Power Supply System) DIN EN 50171

Central power supply system in switching operation with limita­tion of the output power to 500 W / 1 h, 250 W / 3 h or 100 W / 8 h (LPS 230-500-S) and 500 W / 3 h or 200 W / 8 h (LPS 230-500-M) to supply the safety lighting in case of failure of the gene­ral lighting. The LPS is designed to supply the safety lighting DIN EN 50172 (VDE 0108-100) in case of failure of the general power supply.

The operation and display of the test / monitoring equipment is carried out via multi-touch screen. Commissioning is automatic after activation. Switching / operating modes of the final circuit and emergency luminaires can be freely parameterised in the LPS.

Batteries including ageing factor of 1.25 DIN EN IEC 62485-1 (VDE 0510-485-1).

The LPS has a network port via which the device status can be called up using the built-in web server. The possibility of remote control of the LPS via the web server and the storage of building plans is integrated in the LPS.



  • LPS 230-500-S: max. output 500 W / 1 h, 250 W / 3 h or 100 W / 8 h
  • LPS 230-500-M: max. output 500 W / 3 h or 200 W / 8 h
  • 4 final circuits (0.6 A) with circuit and individual luminaire monitoring

  • 4 floating control inputs (freely programmable)
  • 4 relay outputs for messages (freely programmable)
  • 1 connection for MFT4 status panel
  • 1 connection as monitored current loop for external phase monitor
  • 1 contact for safety light blocking during idle times
  • 24 groups freely programmable
  • 24 timers freely programmable
  • Function of direction-variable lights (RIVA / only with ELC address module)
  • RJ-45 TCP-IP network connection
  • Integrated web server with visualization of the mounting locations of the emergency luminaires
  • Web visualization of up to 125 LPS devices
