Unattended Operation
- Please connect the UPS to AC and press the ON button on the front panel, the UPS is turned on and the AC outputs stabilized voltage.
- When AC fails, UPS will supply power to the equipment immediately. And when the battery is used up, UPS will turn off automatically.
- When AC comes back, UPS will turn on automatically.
Protection
- Battery discharge protection: when the battery discharges and the UPS is in inverter mode, the UPS will check and monitor the working status of the battery; when the battery voltage drops to the limited lowest voltage, the inverter will turn off automatically and protect the battery; When AC comes back, the UPS will turn on automatically.
- Short-circuit Protection: when the UPS is in inverter mode and there is shock or short-circuit, UPS will output limited currency, protecting the UPS( When in AC mode, the UPS will be protected first by input fuse and then transfers to the inverter working mode).
Four Kinds of Alarm Function
- When AC fails, and the UPS supplies power, UPS will alarm once every 10 seconds and the beep stops about 40 seconds later.
- When the battery is nearly used up, the UPS will alarm automatically and the
beep frequency is once every 1 second.
- Overload, when the UPS is overloaded, UPS will alarm once every 0,5 second
- Fault, if there is a faulty operation of the UPS, UPS will alarm continuously.
Lock Phase Function
In AC mode, the UPS system automatically tracks AC phase and ensures that the output wave form of the inverter is the same with AC voltage wave form. In this way, it reduces the peak pulse and surge voltage to minimizes the interference and damage to the equipment.
The Function of the Self-set Frequency
When the UPS is turned on for the first time, the acquiescence frequency is 50/60Hz; when it is connected to AC, the frequency is automatically set to 50Hz or 60Hz in accordance with AC.
