This type of product is mainly used for work when the ambient humidity is too high or the temperature is too low, and it is mainly used for power equipment (such as outdoor terminal boxes, high and low voltage control cabinets, hand-cart switchgear, RMU, underground substations, boxes Substation, circuit breaker mechanism box, meter box, etc.), and other occasions that need automatic temperature and humidity control.
Features of heater:
It Adopts internationally advanced aluminum alloy as heat sink, PTC heaters (50W, 100W, 150W) can work stably and reliably under various natural environments for a long time, so it has high sensitivity, fast response speed, small size, long life and easy installation.
Function introduction of heater:
It needs to be used with a temperature and humidity controller. When the humidity is too high or the temperature is too low, the controller outputs the working power to start the heater, forcing the medium to be modified to achieve standard working conditions, until the humidity is reduced to the sum of the set value and the return difference. When the temperature increases to the difference between the set value and the return difference, the controller disconnects the working power and returns to the detection state. This automatically cycles.
Applying ambient conditions of heater:
Atmospheric pressure: 80~110kpa
Insulation resistance: ≥100MΩ
There is no explosion danger in the surrounding medium of the use environment, no corrosive gas, and the concentration of conductive dust should not make the insulation level below the limit value.
