Type PowerPlex® Power Module PM500

~ 264 mm
Typ PowerPlex® Power Modul DC024 von E-T-A: Power Modul mit redundanten Schutzfunktionen für angeschlossene DC Lasten.


The PowerPlex® PM500 is our Power Module with physically isolated CAN bus interface as well as redundant protective functions for connected DC loads. Analog to the PowerPlex® DC024, the device can control and monitor a total of twelve electrical loads. Each module has a manual override function for each 8 A and 25 A output via integral electro-mechanical mini circuit breakers. This allows manual and direct switch-over and ensures access to critical functions.

Product features:

  • Galvanic isolation of the CAN interfaces
  • Configurable outputs (2 x 25 A, 6 x 8 A, 4 x 1 A)
  • Software-controlled overcurrent protection with current measurement
  • Hardware-controlled safety disconnection
  • Self-protection of power transistors
  • Mini circuit breakers with manual switching function

Application examples:

  • Control and monitoring of DC loads
  • Control, dimming and monitoring of lights
  • Control and monitoring of navigation lights
  • Control and monitoring of the anchor light
  • Voltage measurement
  • Current measurement
  • Temperature measurement
  • Control of heating and air-conditioning systems
  • Fuel flow monitoring
  • Fuel tank level / remaining volume
  • Water tank levels / remaining volume
  • pump control and monitoring
