2000W Low Frequency Pure Sine Wave Inverter with Cooper Transformer
Application
Model:LWS 500W-8000W Pure Sine Wave, low frequency Inverter
It is widely applied in wind generator, solar power system, house, vehicle, ship, navigation and places where lack of city power, mobile electricity work and telecommunications device, launch station, emergency EPS.
New Function
1. AC bypass output automatically , NO need to power on the inverter
2. Can charge the batttery even if the inverter is off (as long as it is connected to grid power)
Main features
1. LCD digital display show voltage, load and battery information in real time.
2. Peak power is three times of rated power.
3. Can work with inductive loads such as air conditioner, motor door and so on
4. Accept generator's energy output.
5. Pure sine wave output, available for sensitive loads.
6. Microprocessor control with 4-step progressive charging, 7 battery type selector.
7. Fast and powerful charger with 35A and 70A.
8. High power factor 0.9-1.0, low power consumption.
9. Automatically transfer between battery and line modes.
10. Custom-made communication port USB/RS-232/SNMP
11. Remote control function.
12. Protection against overload, over temperature, over charging, low battery.
