ITR-9-100-DT

This variable speed controller controls single-phase motors with a maximum current of 1,5 A. The requested fan speed can be set via the potentiometer on the front. The supply voltage is 230 VAC. The minimum speed can be adjusted via an internal trimmer. Kick start or soft start acceleration can be selected via a jumper. An illuminated ON-OFF switch is located on the side of the enclosure. This controller is typically used for variable speed control of AC fans or centrifugal pumps in HVAC applications. The fan speed is regulated by varying the motor voltage via phase angle control – Triac technology.
