Devices for temperature control in infrared heating

Electronic power control for infrared heaters,10 to 20A. Miniature IP65 housing with built in heat exchanger

Type 3AS


Solid state relay power control, for metering power of infrared emitters between 5% and 100% of their nominal value.For use in professional and commercial premises, industrial and livestock buildings

Main Features

Set point display: potentiometer graduated in % of power.

Output: zero crossing (no radio interferences), with 10ms cycle time, for use on low thermal inertia medium and long infrared emitters.

Enclosure: 120 x 70 x 65mm, rear in aluminum with cooling fins, front in black PA66.

Protection class: IP54

Mounting: Wall mounting, with 4 removable legs, 70 x 96mm distance

Internal Connection: 4 ways 6mm ², ceramic terminal block. (2 power input terminals, 2 power output terminals ). 2 earth terminals.

Cables Input-Output: by 2 cable glands, M20, polyamide.

Residual voltage at off: ≤ 1.5V

Leakage current at off : ≤ 4mA

Ambient temperature: -20 to +70 ° C

Isolation Voltage: 2000VAC

Insulation resistance: 500MΩ/500VDC


-Like all solid state relays, this device dissipates about 0.5% of the power by the Joule effect.

– Install this unit in a line with a power switch and an appropriate circuit breaker.

– Not to be used for electric motors speed control
