Protection:

Overload: Overload exceeds 110%, automatic shutdown in 30 secs; Overload exceeds 120%, automatic shutdown in 2 secs; Under mains supply mode, it will not shutdown if overload, just keeping sound.

Short - circuit: Output short-circuit, automatic shutdown after keeping sound 20 secs

Battery: high or low voltage protection

Reverse polarity: reverse polarity protection(optional）

Alarm

A: Without alarm sound if work normally under mains supply mode, when mains supply cut off, turn into battery mode, keeping sound 4 times every 30 seconds.

B: Keeping sound every seconds for second time alarm of Battery low voltage; send out sharp sound under machine fault.

C: Keeping sound every seconds under Overload

Note: All specifications are subject to change without prior notice

General Features：

A． DSP Intelligent control chip

B． Result fetched from Effective value, not Average value

C． Photoelectricity isolation circuitry technology

D. Switching power is supplied by independent system

E. True Over Temperature Protection

F. Full bridge rectifier and mainboard structure are highly optimized. Input and output circuits are isolated.

G. Strong loading capacity with true onetime soft start.

H. New and original electronic components

I. Internal circuit lines and signal lines are based on plug-pull blocks, not welding

1. The whole series controlled by program of DSP intelligent chip

2. The whole series with automatic AC charger and automatic AC mains switch function. Switch time within 5ms.

Others: More than 10ms. The less time switch takes, the less impact to the loading, especially for office, medical, communications etc. terminal customers.

3. Continuous stable output voltage：No matter how low or how high the AC input voltage is, with voltage stabilizer our inverter provides standard 110V or 220V stable output, which keeps the loading works stably. Wide stabilizing range of AC input optional.

4. Brand new and imported U.S. brand Infineon IR MOSFETs are used for the whole series:

1000W-3000W：US IR brand MOSFETs

4000W-6000W：US IR brand COOL MOS 3077 MOSFETs, higher level MOSFETs

All MOSFETs are brand new and original imported, with certificate of origin, batch and date of production to guarantee our quality.

Others products： MOSFETs are made in China.

5. Transfer efficiency: 83-85%

6.Full range of 1 year warranty
