|Main Application: condensation in electrical enclosures and cabinets can be critical for electrical components and safety. This humidistat is designed to switch on a heater or a ventilating fan when the relative humidity raises at dangerous levels, when there is a risk to reach the dew point usually around 65%.
It can also be used to switch on humidifiers, dehumidifiers, or other devices.
Humidity sensing element: hygroscopic polymer film with special treatment, produced by Ultimheat, ensuring a fast response, long life and high stability
Setting range: 35 to 95% RH
Measuring accuracy: ±5% RH
Differential at 50% RH: 8% RH (±3% RH )
Measuring medium: air, pressure-less, non-aggressive
Electrical contact: silver contacts, SPDT, 5A 250V
Connection: 3 screw terminals for 1.5mm² wires, max torque 0.5Nm
Mounting: clip for 35mm DIN rail EN50022
Operating temperature: 0 to+60°C (+32 to +140F)
Storage temperature: -20 to +70°C (-4 to +158F)
Mounting position: vertical
Voltage supply: the humidistat should be mounted such that there is no buildup of condensate on or in the device. If the voltage supply is higher than 48V there is a risk of voltage arcing in the event of water condensation on the micro-switch or connecting terminals which might destroy the control.
Ingress protection class: IP30
Dimension: 67x50x 36mm
Maintenance: The humidity sensing ribbon is maintenance-free in clean air. Air containing solvent can cause measuring errors and failure, depending on the type and concentration. Deposits such as resin aerosols, lacquer aerosols, smokes, which eventually form a water-repellent ﬁlm are harmful for the measuring element.
