Specifications

It designed for the telecommunications industry, which can output the pure sine wave voltage of 220V in long distance

Introduction:

DA-3000AB 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 24V 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 sine wave inverter DA-3000AB is specifically designed for the telecommunications industry, which can output the pure sine wave voltage of 220V in long distance, and which can supply power to the equipment within 5 km. It is apply to 24V (or-24V) 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

6. Output the pure sine wave voltage of 220V in long distance
