DC monitoring module 24 V - with accumulator test

   

DC-UPS module until 20 A with an acitve accumulator test according to VDE 0833

The DC-ÜM 20 is a DIN-Rail monitoring module that can be combined with DIN-Rail power supplies which work with constant voltages and currents.

Power supply, accumulator, load plus fault message lines get connected with the module. The fault massages are available as a optical signal (LED), as well as a potential-free interface.

  • Two power supply inputs for redundant operation without current icrease
  • Dynamic accumulator test
  • Deep discharge protection
  • Operation display and fault message interfaces
  • Accumulator protection
TYPE INPUT (in VDC) OUTPUT (in VDC) DIMENSIONS (in mm) POWER (in W)

DC monitoring module 24V - without accumulator test

    

DC-UPS module until 20 A without accumulator test

The DIN-Rail monitoring module can be applied with power supplies with constant voltage and current. Accumulator, load and fault messages get connected with the module.

    

DC-ÜM 22 with TIMER

In case of power failure a timer gets started that disconnects the accumulator after approx. 3 minutes. Parallel to this a deep discharge protection is active that disconnects the accumulator before it reaches the deep discharge protection boundary (at approx. 19V). If the power supply voltage returns the system gets started immediately.

  • Operating display and fault message interfaces
  • Deep discharge interfaces
  • Accumulator protection
  • Separating diode for power supply
  • Automatic accumulator abscission
