Intelligent protection for inrush/overload/short circuit protection
the ups can accept 8 times inrush no transfer to by pass feed
Mains available: when over-load/short-circuit, ups transfer to bypass feed, if abnormal status removed, it auto-transfer back to inverter feed.
Mains unavailable: over load, UPS STS, re-start again afterward, supply in normal, if overload, UPS will automatically shut down after three times, it needs manually switch it up. instant short circuit: inverter work normally without transfer to bypass. When it's short circuit within 10 seconds: inverter switch off, re-start after 15 seconds, try to clear way faulty, if without clear away short circuit after starting for three times, then open it up manually.

Features & Benefits | |
|
System features | |
| Temperature controlled fan | Fan running above 50℃ to lengthen its life. |
| Microprocessor control, modular design | Controller adopts high speed microprocessor to increase reliability. Modular design and interchangeable control card offer the advantages of easy service and low MTTR to 40min. |
| Dual redundant operation increasing MTBF | The UPS can operate in redundant operation to increase the reliability. if the MTBF of an unitary UPS is 50 000Hrs, it can be extended up to 450,000Hrs for a redundant operation system, when Mains is high reliable |
| Inverter standby operation (option) | Be designed for real applications like lightning system in mine, it up the UPS efficiency to 98%. |
| Common battery operation (option) | It reduces the discharging rate of battery, and lengthens the back up time from 2 to 4 times, This advanced mode can reduce the battery cost. |
| battery cold start,long back up time charger | The strong charger built-in ups is compatible for long back up feed and the ups can be cold started by battery power without Mains. |
| battery self-testing | Without off the input power, the battery can be self-tested, to ensure continuous power supply and maintenance of the battery. |
| Battery PWM control battery environment protection PWM controlling approach | IGBT inverter has instant current fetch samples circuit, then feedback to working current to ensure having sine wave input under load from computer, if in the highest flight of transient response, the precision of its can be up to 1%. |
