Product description

This variable speed controller has an analogue input. It controls single-phase motors. The (combined) maximum motor current is 6 A. The TK monitoring function deactivates the motor in case of overheating. The alarm output is activated in case of motor problems. During normal operation, the motor can be activated or deactivated via the integrated ON-OFF switch or remotely via the digital input. High and low speed are adjustable via internal trimmers. The analogue input type can be selected via jumpers or via Modbus RTU (0-10 V or 0-20 mA). Kick start or soft start acceleration and different operating modes are selectable via Modbus RTU. The unregulated output is active when the motor is enabled. The supply voltage is 230 VAC. The AC fan speed is regulated by varying the motor voltage via phase angle control - Triac technology.

Additional specifications and description

Analogue 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.

Remote control
The motor can be enabled or disabled via the illuminated on-off switch or remotely. Via an external switch, it is possible to start the motor remotely - this optional switch can be connected to the digital input of the fan speed controller.

Easy to configure
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.

Solid enclosure
The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is flame extinguishing in case of fire, very though and offers good protection against impacts. The enclosure can be surface mounted and offers an IP54 protection against ingress of dirt, dust and moisture.

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.

Thermal motor protection
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.

Alarm output
This fan speed controller has an alarm output to generate alerts in case of motor failure.
E.g. the alarm output can be used to signal motor problems via an external buzzer or alert light.
