400 V fan speed controller 0-10 V | DIN rail | 6 A
Product description
TVSS5 is a fan speed controller designed for three-phase, 400 V, voltage-controllable electric motors with a maximum current of 6 A. It provides infinitely variable fan speed control according to a standard input control signal, which can be selected via a slide switch between 0-10 VDC and 0-20 mA.
This controller is equipped with Modbus RTU communication and offers remote on/off functionality via an external switch or Modbus. It provides a wide range of features, including kick start or soft start motor acceleration, as well as adjustable min. and max. output voltage settings and an adjustable off level via internal trimmers or Modbus. Thermal contacts are also included to provide motor overheating protection.
The device features one regulated output for the motor and one low voltage supply output (+12 VDC / 1 mA) for an external potentiometer. LED indicators provide clear visual feedback for normal operation and alarm status. The controller is designed for DIN rail mounting.

Additional specifications and description
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.
The motor can be enabled or disabled via an external switch. This optional switch can be connect to the digital input of the fan speed controller.
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.
The enclosure can be DIN rail mounted and offers an IP20 protection against ingress of dirt, dust and moisture. The plastic cover offers protection against contact with live parts.
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.
