Low frequency inverter built in AC-DC battery charger

DC-AC Inverter Technical:

1, Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers can set start mode according to the nature of their load.

2, The output frequency can be set, this function is very convenient for customer.

3, The output voltage can be set between +20 % to -40 % of rated voltage. It’s a great convenience to users.

4, The DC input voltage range can also be set. Over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point all can be set via the LCD panel. Convenient for increasing or reducing the quantity of batteries, photovoltaic modules also can be used flexibly.

5, Pure sine wave output. with good transient response less than 40MS, little harmonic distortion, higher conversion efficiency and stable output voltage.

6, Powerful data display and fault instruction function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.

7, Using the sixth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It’s service life can up to 15 years or more.

8, Wide input voltage can be set according to customer’s requirement. Input voltage range can be selected from 100-400V or 480-850V.

9, Product have passed the European CE (EMC and LVD) certificated and accredited by Australia CEC energy network.
