Fan speed controller 230 VAC - 0,5 A


Product description

This is a variable speed controller. It regulates fan speed from high to low. Designed for single-phase voltage controllable motors with a maximum current of 0,5 A. The minimum speed can be adjusted via an internal trimmer. The enclosure allows inset mounting (IP44) or surface mounting (IP54). Phase angle control (Triac technology) is used to vary the motor voltage and to regulate the motor speed.

Title
Description

Manual fan speed control - AC voltage controllable motor

This solution controls AC fans with single-phase voltage controllable motor. The maximum motor current is 0,5 A. Typically, it controls AC fan speed in HVAC applications. The fan speed can be adjusted via the potentiometer. This potentiometer has an OFF position. It controls fan speed from high to low speed. The supply voltage is 230 VAC. The fan speed is regulated by varying the motor voltage via phase angle control - Triac technology.

Frequently asked questions

:
The unregulated output provides a voltage of 230 VAC (Imax 2 A) as soon as the motor is enabled. The unregulated output can be used to power a 'motor run indicator light' or to supply the start up capacitor in case of single phase motors with external start up capacitor.

If the motor is accidentily connected to the unregulated output, it will run at maximum speed once enabled.
During operation, asynchronous motors heat up due to electric currents flowing through the motor windings. The air flow generated by the motor compensates this heating proces. If the motor speed is not high enough, the excessive heat might cause melting of the isolation of the motor windings and damage the motor. In some extreme cases, a low motor voltage might even cause stalling of the motor: electric currents are flowing through the motor windings while the motor is at standstill (stalled or blocked). To avoid this, the minimum motor speed should be set high enough to avoid excessive heating or stalling of the motor. The minimum required motor voltage depends on the type and brand of the motor.
