● 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
