7500~15000W Power inverter for telecommunication use

It has a high conversion efficiency and with a strong non-linear load drive capability

Introduction:

This series of the DA-D power supply uses the U.S. INTEL's 16-bit dedicated micro-processor chip to contral. The main circuit using the U.S. IR's high-power field effect transistor(FET)and high-quality isolation transformer, have the following advantages: high reliability, high efficiency, strong protection function, small waveform distortion, low price etc.

                                          

It can convert the 220V DC power to the pure sine wave AC power for 220V, 50Hz, which is stable voltage and frequency with low noise.The product has a high conversion efficiency (it is up to 85% above at full load conditions). Which has a strong non-linear load drive capability as well.

This series of sine wave inverter DA-7.5~30KD is specifically designed for the power room, which is apply to the 220V DC power (DC-screen) program-controlled switches, computer rooms, network, billing servers and emergency lighting and other places.

Features:

1. High efficiency and reliability

2. Strong protection function

3. With computer inspection and monitoring

4. Automatic bypass conversion

5. Pure sine wave
