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.
