AC fan speed controller 0-10 V | DIN rail | TK monitoring | 3 A
Product description
The MVSS1-30CDM variable fan speed controller is a sophisticated solution for precise control of 230 V single-phase tension controllable motors with maximum currect of 3 A. It features Modbus RTU communication, alarm relay output, and thermal contacts for overheating protection.
It also offers remote control options, adjustable levels, and time-limited motor operation. The TK monitoring function ensures motor deactivation in case of overheating.
Versatile features, including kick start, soft start, and multiple operating modes, make it a reliable choice for expert motor speed control, easily DIN-rail mounted.
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 an external switch. This optional switch can be connect 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.

DIN rail mounting
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.

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.
