Working Principle AC input is rectified and switched at high frequency. Transformer isolates and steps down; secondary rectifier produces DC24 V. Battery connects across output. The charger maintains float voltage; when AC fails, battery discharges to load. Monitoring circuits protect output and battery.
Installation Requirements
- Insert into DC panel rack
- Select AC input voltage
- Connect battery with correct polarity
- Connect DC load bus
- Temperature 0 °C to +50 °C
- Grounding
- Verify float voltage after power-up
- Redundant rectifiers share current
Precautions
- Battery polarity must not be reversed
- Do not short DC output
- Battery ventilation required
- Replace electrolytic capacitors at end of life
- Store spares in dry environment
- Periodically measure battery voltage
- Disconnect AC before service
