Product Description

power inverter pure sine wave inverter SDP-30KW

Sandi pure sine wave series inverter is one of the most advanced DC to AC conversion products in the world, it has the main advantages of high quality sine wave AC output, microcomputer control, humanness design, and it is simple, stable, no noise and no pollution. It is suitable use for areas without electricity, vehicles, ships, solar energy, wind turbine etc. The inverter can also supply AC voltage to all kinds of power tools, air conditioners, electric motors, refrigerators, fluorescent lights, televisions, electric fans and other power supply.

The inverter output waveform is pure sine wave; this kind of AC power is suitable for most industrial electronics and home appliances, the power supply features much better than other modified sine wave and square wave.


Technical Features:

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 fifth 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 100-500V or 200-850V.

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