The WHD series temperature and humidity controllers use sensors to detect the temperature and humidity inside the cabinet and regulate them by controlling external fans and heaters. They effectively prevent equipment failures caused by low or high temperatures as well as creeping discharge and flashover accidents caused by moisture or condensation.
Applications
Medium- and high-voltage switchgear, terminal boxes, ring main units, and box-type substations.
Ordering Example
Model: WHD46-22
Technical requirements: heating and dehumidification when humidity ≥85%RH, stop at ≤80%RH; forced-air cooling when temperature ≥40°C, heating when temperature ≤5°C.
Communication protocol: None.
Auxiliary power supply: AC/DC 220V.
