Power Pack for VCB Panels

Brand: Alan Electronic System Pvt. Ltd.

Introduction:
The power pack serves as a power source for VCB panels in substations where a station battery supply is unavailable. It is charged through a line-connected PT (burden 200VA) and provides DC power to operate close/trip coils, protection relays, and other essential loads.

Technical Specifications:

  • Input Voltage: 110 VAC or 230 VAC ±20%, -30%
  • Input Burden: Less than 50 VA during charging (without output load)
  • Output Voltage Options: 24VDC / 30VDC / 48VDC / 110VDC / 220VDC
  • Output Load: 100W nominal
  • Continuous Load: 100W (for 10 minutes)
  • Impulse Load: 450W for 240 milliseconds (minimum 10 pulses)
  • Battery Charging Period: 8 hours
  • Overall Dimensions: 280 mm (W) x 190 mm (H) x 210 mm (D)
  • Weight: 7.0 kg

Note: Please specify the required input and output voltage when ordering.

Protections:

  • Overvoltage Protection: Ensures that the output DC voltage does not exceed the specified value during no-load operation or battery charging.
  • Short Circuit Protection: Automatically resumes output once the short circuit condition is resolved, without requiring a manual reset.
