9-step fan speed controller | DIN rail | 2,5 A


Product description

DIN-rail mounted fan speed controller for single-phase motors. The maximum current is 2,5 A. The fan speed is regulated by varying the motor voltage in 9 steps 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 can be selected via Modbus RTU. The enclosure is designed for DIN rail mounting.

Additional specifications and description


9-step fan speed control
The fan speed can be adjusted in 9 steps via the up and down arrows. By pressing the up and down button simultaneously during 3 seconds, the motor can be activated or deactivated. The selected step is visualised via the 7-segment LED display.

Easy to configure
This fan speed controller doesn't require configuration. The default settings will do for most applications. If necessary, the settings can be adjusted via the 3-button keyboard interface or via Modbus RTU.
E.g. the minimum and maximum speed levels can be adjusted if necessary, softstart acceleration can be replaced by kickstart acceleration, etc. We advise to read the Modbus register map for a complete overview of the parameters. 

Superb quality
This fan speed controller is manufactured in Europe using the most reliable and modern electronic components. It can control (multiple) motors with a total maximum current equal to its rated current. On a continuous basis. There is no need to overdimension this controller.

Kickstart or softstart acceleration?
The motor can be accelerated in softstart or in kickstart mode. In softstart mode, the motor will accelerate smoothly towards the set fan speed. In kickstart mode, the motor will immediately start running at full speed and slow down towards the set fan speed after a few seconds.

Unregulated output
The unregulated output (230 VAC) is active when the motor is enabled.  It can be used to control an external run-indicator, a damper, etc.
E.g. when the fan is deactivated, the damper is closed. When the fan is active, the damper is open.

DIN rail mounting
This fan speed controller can be installed on a DIN rail inside an electric cabinet. The enclosure provides an IP30 protection against the ingress of dirt and dust.
