CNS 15156-200/IEC 62271-200

Built-in humidity sensor in the dehumidifier, operable without output power.
It controls dehumidification devices or heaters to raise air dew point, preventing component corrosion and false alarms caused by dew point, and can also control cooling fans, warning lights, etc.
Application examples: switch cabinets, control cabinets, machine cabinets, electronic and communication devices, etc.
