Brand: PR Electronics
Request a Quote
  • 230 or 115 VAC primary voltage
  • 24 VDC output voltage
  • Double isolation by 3.75 kVAC
  • 48 Watt output power, short circuit-protected
  • Thermal protection against overload
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.
  • 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.
