Manual motor control


Variable speed controllers with potentiometer. They control single-phase voltage controllable motors with a maximum current of 10 A. Via the integrated potentiometer, AC fan speed can be regulated manually.

NEW - High to low fan speed controllers

NEW - High to low fan speed controllers
SDX are AC fan speed controllers. They regulate fan speed from high to low. Designed for single-phase voltage controllable motors with a maximum current of 3 A. The enclosure allows inset mounting or surface mounting. The new SDX series are microprocessor controlled to guarantee accurate motor control and to minimise motor noise. Phase angle control - Triac technology - is used to vary the motor voltage and to regulate the motor speed.

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.

ITRS9 series are electronic fan speed controllers. They control single-phase voltage controllable motors with a maximum current of 10 A. The fan speed is regulated by varying the motor voltage via phase angle control - Triac technology. The minimum and maximum speed is adjustable via internal trimmers. There are two start-up modes - kick start and soft start. The motor can be enabled via the integrated ON-OFF switch or via the digital input. The TK monitoring function deactivates the motor in case of overheating. The alarm output indicates motor problems.

Fan speed controllers for DIN rail

Fan speed controllers for DIN rail
DRE series are electronic fan speed controllers. They control single-phase voltage controllable motors with a maximum current of 2,5 A. They regulate fan speed by varying the motor voltage via phase angle control - Triac technology. The power supply is 230 VAC. The minimum and maximum speed can be adjusted via Modbus RTU. The motor voltage is regulated via the 3-button keybord in the range between the selected minimum and maximum speed. Kick start or soft start acceleration can be selected via Modbus RTU. The enclosure is designed for DIN rail mounting.
