Control a fan

Fan speed controllers regulate the supply of fresh air or the exhaust of stale air in function of the need. The air flow volume can be adjusted manually or automatically according to the demand. In case of manual control, the fan speed can be adjusted via a switch or potentiometer. This can be done locally or remotely. For automatic fan speed control, an HVAC sensor is connected to the AC fan speed controller or EC fan.

DRZ------001

AC motor 2,5 A | variable speed control | DIN rail | softstart

Variable speed control for AC fans with single-phase motor. The maximum motor current is 2,5 A. The enclosure requires DIN rail mounting. Fan speed can be adjusted via the potentiometer from low to high speed. In OFF position, the motor is disabled. The supply voltage is 230 VAC. The fan speed is regulated by varying the motor voltage via phase angle control - Triac technology.
