Variable speed control - separate ON-OFF switch

ITR-9 series are AC fan speed controllers. They control single-phase voltage controllable motors with a maximum current of 10 A. They regulate fan speed by varying the motor voltage via phase angle control - Triac technology. The minimum speed is adjustable via an internal trimmer. There are two start-up modes - kick start and soft start. The motor can be activated or deactivated via the integrated ON-OFF switch.
