Advanced features

  • The power supply is based on primary switchmode technology to achieve a high efficiency.
  • An internally mounted potentiometer allows for a ±5% adjustment of the output voltage.

Application

  • General 24 VDC supply for equipment that requires a stabilised DC voltage.
  • Two units can be connected in series to achieve a plus / minus supply or a higher output voltage.
  • Separation of circuits in safety installations according to the PELV/SELV norm.
  • Galvanic isolation between the primary and the secondary voltage is achieved through the double-isolated safety transformer.

Technical characteristics

  • A green LED in the front of the module indicates an active primary voltage.
  • Input circuit protected with a 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.
