Constant voltage power supply

Adopt advanced sine wave pulse width modulate IGBT high frequency inversion technique, inside is AC-DC-AC structure, eliminate the electricity net disturb, output pure wave, stable voltage and frequency, high precision, light weight, small volume, output use isolation transformer. It can cooperate with the generator to make good quality uninterruptable power supply system.
Main technique parameter:
1. Input voltage: 130~280V
2. Input frequency: 35~70Hz
3. Output voltage: 220Vÿ?.5%
4. Output frequency: 50Hzÿ?.01%
5. Wave distortion: <1%
6. Isolation transformer output, safe and credible
7. Auto-protection and alarm for output overvoltage, overcurrent, overheat, short circuit.
8. Efficiency is more than 90%, adapt to large range of load, inductance, capacitance, resistance, and any mixed load.
9. Quick dynamic feedback, when the load changes from 0 to 100%, the steady reaction time<0.1S.
10. Regarding the input/output voltage and frequency, please explain when you purchase.
