AC fan speed controller | analogue input | TK monitoring | 6 A
Product description
Explore the EVSS1-60-DM electronic speed controller, an advanced solution for automatic speed control of single-phase voltage-controllable motors (230 VAC / 50—60 Hz).
Equipped with Modbus RTU (RS485) communication, alarm relay output, and thermal contacts for motor overheating protection.
With a maximum current of 6 A, the EVSS1 controllers offer remote control options, adjustable off level, and min. and max. output voltage settings.
The TK monitoring function deactivates the motor in case of overheating, ensuring reliable protection.
The integrated ON-OFF switch, kick start, soft start and digital input enable versatile motor control, while internal trimmers allow precise adjustments.
Trust the EVSS1-60-DM for expert motor speed control with extensive safety features
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 tough 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.

Disable ON OFF switch
For the 1,5 A and 3 A EVSS1 series, the ON-OFF switch can be disabled by connecting the 230 VAC supply voltage to the unregulated output (L1). In that case, the connection terminal L is not used. When the supply voltage is connected to the unregulated output, the motor is always activated - regardless of the ON-OFF switch position.
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.
