400 V fan speed controller 0-10 V | DIN rail | 6 A
Product description
Precise speed control for three-phase 400V voltage-controllable electric motors, handling up to 6 A.
High and low speeds are adjustable via internal trimmers.
Includes Modbus RTU communication and thermal contacts for overheating protection.
Offers remote control options, adjustable levels, and kickstart or softstart motor acceleration.
Analog input type is selectable (0-10 V or 0-20 mA) via jumpers or Modbus RTU.
TK monitoring function ensures motor deactivation upon overheating.
DIN-rail mountable for easy installation.
Additional specifications and description
How Is Fan Speed Controlled via Analog Input?
The requested fan speed can be set via the analogue input signal. This analogue signal can be 0-10V or 0-20 mA. This analogue input can be set in ascending or descending mode. In ascending mode, the motor will run at low speed when the analogue signal is at its minimum value (0 V). The motor will run at high speed when the analogue input is maximum (10 V). In descending mode, the operation is inversed.
In case there is no 0-10V signal available, you can connect an external 10 KOhm potentiometer via the integrated 12 VDC power supply.

How Can Controller Settings Be Customized?
For most applications, this variable speed controller can be used with the default settings. If necessary, the settings can be customised via Modbus RTU or via the dip switches and internal trimmers.

How Does Motor Overheating Protection (TK Monitoring) Work?
This fan speed controller can monitor thermal motor contacts (TK or thermal contacts measure temperature in the motor windings). In case of motor overheating, the TK monitoring function will disable the motor to prevent motor damage. If your motor is not equipped with TK contacts, bridge both TK terminals to simulate normal motor temperature.
