Advanced features

  • The regulator is based on primary switchmode technology to achieve a high efficiency.
  • The outputs are adjustable from a front potentiometer in the range 5...24 VDC or from an external potentiometer.


  • General voltage regulator for external transformer used in connection with measurement systems requiring fixed stabilized 24 VDC.
  • Supply for any other sensors, transmitters or a general variable voltage regulator in the range 5...24 VDC.
  • Used as a power efficient pre-regulator for 5 VDC linear regulator (e.g. from 32 V to 8 V).
  • Used as adjustable power supply controlled from external potentiometer.

Technical characteristics

  • A green LED indicates active output.
  • AC or DC input voltages.
  • A rectifier bridge allows free choice of polarity for the DC input.
  • Mounting for a standard 11-pole socket which can be adapted for DIN rail or plate use with PR’s 7023 adaptor and 7024 mounting keying.
