Advanced features

  • The power supply is based on switch mode technology to achieve a high efficiency.
  • The outputs are adjustable by 2 front potentiometers in the ranges 5...24 VDC.

Application

  • Supply for small measuring systems that demand 2 stabilized voltages.
  • Either as a combination of positive and negative voltages, or as 2 separate supplies as required.
  • The two supplies are galvanically separated with 500 VAC test voltage and can be connected in series or used as two independent supplies with or without common gnd. 
  • Separation of circuits in safety installations according to PELV/SELV.
  • Galvanic isolation between the primary and the secondary voltage is achieved through the double-isolated safety transformer.

Technical characteristics

  • Two green LEDs, Power ON 1 and Power ON 2, indicate active outputs.
  • By connecting the two outputs in series, 10...48 VDC or ±5...24 VDC can be achieved.
  • The input circuit is protected with a bimetal thermal fuse.
  • DC output short circuit protection with current limiter.
  • 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.
