Efficiency

≥93%

Environment

Operating site

●  Install vertically in a well-ventilated electrical cabinet. Horizontal or other installation methods are not allowed.
● The cooling medium is air.
● Installed in an environment free from direct sunlight, dust, corrosive gases, flammable gases, no oil mist, no steam, no dripping.

Ambient temperature

● −10～+40℃
● Derating use when the temperature between 40 to 50℃, the rated output current is reduced by 1% for every 1 °C increasing.

Humidity

5～95%, no condensation is allowed.

Altitude

● 0～2000 meters
● Derating use when the altitude over 1000 meters, the rated output current is reduced by 1% for every 100-meter rising.

Vibration

3.5 m/s2 ，2~9Hz；10 m/s2 ，9~200Hz；15 m/s2 ，200~500Hz

Storage temperature

−40~+70C
