DC Power Supply for Relay Testing


  • Multiple outputs of one power supply serve many devices. Connect protective relays, communications processors, and other devices to two 24-Vdc and two 125-Vdc outputs (50 VA maximum). Or connect the two 24-Vdc outputs in series for 48 Vdc or connect the two 125-Vdc outputs in series for 250 Vdc.
  • Linear design provides “stiff” low-impedance outputs to start and serve high-surge loads
  • Connect station or plant support equipment (transducers, sensors, and more) to the general-purpose +5-Vdc, +15-Vdc, and –15-Vdc regulated outputs
