2. WORKING PRINCIPLE
2.1. System circuit diagram
2.2. Normal power supplies
When the UPS works in normal condition, miscellaneous waves of high-frequency are eliminated by wave filter and the
batteries are charged by the charger and maintained like this in full power condition. The output voltage is regulated via
autotransformer in case of fluctuations in mains voltage.
2.3. Main power off
In main power off condition, the batteries are promptly supplying current to the inverter. Then – after passing through the
wave filter – the power can be sent to user’s equipment without interruption.
2.4. Power supply by bypass
The bypass mode only happens in the following conditions:
1.
overload;
2.
UPS failure;
3.
Switch-on: keep pressing the ON button for 3 seconds, the UPS will be in process of soft starting within 15 seconds;
4.
Switch-off: keep pressing the OFF button for 3 seconds and the UPS turns to bypass mode.
