Descriere

  • Isolated variable 1-300 Vdc source
  • Isolated variable 1-240 Vac source
  • 10 ampere continuous current

 

The Vanguard Universal Power Supply Series 2 (UPS-S2) is designed and produced to meet a utility company's substation needs for an independent AC/DC power source. Both the AC and DC Voltage sources are capable of supplying 10 amperes continuously.

 

The variable DC power supply (1-300 Vdc) is ideal for use as a substitute primary power source when station batteries are not available. The UPSS2 is ideal for operating circuit breakers, powering substation relays or for unregulated charging of substation batteries. The AC power supply is a variable isolated power source (1-240 Vac) that can be used to power other equipment in the substation.
