Device model: PS-4sv
Device type: PS

Switch-mode power supplies are designed to supply elements of gas detection systems (control modules, detectors, warning boards and signalling devices) with a nominal supply voltage of 12VDC or 24VDC.

They have a possibility of automatic power backup from an internal gel battery (or a pair of batteries) type AKU.


  • output voltage separated by galvanic separation;
  • possibility to back up the power supply from the internal maintenance-free battery (ordered separately) in case of mains voltage loss;
  • output protection against overload and short circuit;
  • limit of the battery charging current;
  • optical indication of the presence of input and output voltage;
  • optional: module with relay outputs to indicate mains failure and presence of output voltage.
