Universal Power Supply CBUPS

Universal Power Supply CBUPS

The Amperis Universal Power Supply (CBUPS) is designed to meet a utility company’s substation needs for an independent AC/DC power source. The CBUPS’ AC and DC voltage sources can each supply up to 10 amperes.

The variable DC power supply (10 – 300 Vdc) is ideal for use as a substitute primary power source when substation batteries are not available. The CBUPS is best suited for operating circuit-breakers, powering substation relays, or for un-regulated charging of substation batteries. The AC power supply is a variable isolated power source (10 – 240 Vac) that can be used to power other equipment in the substation.

CBUPS Features

  • Isolated variable 10 – 300 Vdc source
  • Isolated variable 10 – 240 Vac source
  • 10 ampere continuous current

The Universal Power Supply delivers several important features:

  • All output power sources are isolated from the primary power input by an isolation transformer.
  • Voltage outputs are variable (auto-transformer) via a front panel control knob.
  • The primary power input is selectable (120Vac or 240Vac).
  • All voltage outputs are capable of supplying a 10 ampere load.

For ease of operation, the power output path is clearly outlined on the control panel. This provides an intuitive visual guide for making the appropriate selections for a particular operating configuration. The Universal Power Supply is housed in a heavy-duty, impact-resistant plastic enclosure and is furnished with a power cord, grounding cable, and a pair of test leads with alligator clips.
