Type designation
Service conditions
- A Ambient temperature: Max: +40℃, Min: -5℃, Daily average temperature not more than 35℃.
- B Altitude: Gradient of slope is not more than 5 degrees when installing, altitude is not more than 2000m.
- C Relative humidity: Air is clean and the relative humidity is not more than 50% when the max temperature is +40℃. Higher relative humidity is allowed at lower temperatures (such as 90% humidity when the temperature is +20℃), but the effect of condensation should be considered due to temperature changes.
- D Medium constraints: No explosion risks medium, and no corrosive gas or conductive dust. For special requirements or conditions not consistent with normal service conditions, please negotiate with us.
