Ambient

Place to be used

Indoor; no corrosive gases, no conductive dust; well ventilated.

Altitude

The altitude does not exceed 1000m, if it exceeds 1000m and is less than 3000m, the current is reduced by 1% for each additional 100m.

Ambient temperature

Ambient temperature should be between -10℃～+40℃, +40℃～+50℃ should be derated, the current is derated by 2% for every 1℃ rise in temperature.

Ambient humidity

The relative humidity is no more  than 90%, without dew condensation .

Vibration

Vibration  force should be below 0.5G

Structure

Protection Class

IP20

Cooling Mode
