Intelligent temperature and humidity controller, switchgear, ring main unit, heating and dehumidification control

1、 Core functions

Accurate control of temperature and humidity

Real time monitoring of the internal temperature and humidity of the device through built-in sensors. When the temperature is detected to be below -40 ℃ or above 40 ℃ and the humidity exceeds 90% RH, the heating or ventilation device will be automatically triggered to prevent equipment failure caused by temperature and humidity.

Supports independent control of temperature and humidity in two channels, allowing for flexible monitoring of different areas (such as inside switch cabinets, terminal boxes, etc.).

Fault prevention

Effectively avoiding safety hazards such as creepage and flashover caused by condensation, and improving the reliability of power equipment operation.

Intelligent alarm and communication

Provide RS485 communication interface (supporting Modbus RTU protocol), which can be connected to the monitoring system to achieve remote data reading and device control.

Support fault alarm output (such as temperature and humidity exceeding limits, sensor disconnection, etc.) for timely maintenance.
