Speed regulator - Import export

This control unit has two 0-10 Volt outputs to regulate the EC fans. Via the 2 tacho inputs you can directly monitor the status of the fans and their speed, if tacho signals are available on the fans. HVAC sensors or potentiometers can be connected to the unit, via Modbus RTU communication or 2 analogue inputs. The built-in 24 VDC power supply can feed the external sensors or potentiometers. The controller itself needs a supply voltage between 85 - 305 VAC. Application specific firmware is needed for the unit to function. This firmware can be downloaded via Senteraweb, our online HVAC portal, where we already made a limited number of specific firmware version available, used in typical HVAC applications like destratification. The only thing that needs to be done is to select the appropriate functionality on the solution page of our website and download the firmware. No additional programming is required. TCMF8 is also available - for AC fan speed control.

This self-calibrating CO2 sensor measures CO2 as well as temperature, relative humidity and ambient light conditions. It needs a 24 VAC supply voltage. This sensor can also directly control an EC-fan, AC fan speed controller or frequency inverter. It has 1 single analogue / modulating output depending on the highest measured value for temperature, humidity or carbon dioxide. If you only want to use it for measuring CO2, you can deactivate the temperature or humidity measurement. The FCMFX-series are available for different types of supply voltages such as 24 VDC, 24 VAC/VDC or 230 VAC. All version have 3 LEDS on the frontpanel showing whether the measured value is within or out of range. Additionally they are available in a version with audible alert. All parameters are accessible via Modbus RTU. This sensor doesn't need to be configured. Once installed it's ready for use.

The STR-1-15L22 is a transformer fan speed controller with which you can manually regulate the fan speed of single-phase motors in 5 steps. The unit also has an off-position. It needs a 230 VAC/50-60 Hz supply voltage and has an unregulated output of 230 VAC that can control a damper, an external status indicator, etc. This output is active as soon as the motor is enabled. The sinusoidal shape of the generated motor voltage results in an exceptionally quiet motor operation and extended service life. The special impregnated coating reduces the electrical noise from the built-in autotransformer. This series is available in different amperes. The casing of the controllers up to 7,5 A is made from high quality plastic, while the models above 7,5 A have a metal housing. This transformer doesn't need any configuration. Once installed, it's ready for use.

Stepless regulation of EC fans, AC fan speed controllers or frequency inverters is what this potentiometer stands for. It has an off-position and the output value depends on the position of the rotary knob on the front. This potentiometer has a dry contact output that can be used to remotely switch on/off a fan, open/close a damper etc. The dry contact will be open when the know is turned completely counter clockwise. The input voltage for this potentiometer can lie between 0 - 24 VDC. The version handling 0 - 12 VDC is called the MTP-X10K-NA. The splash-proof housing of both potentiometers allows flush (IP44) or surface mounting (IP54).

This controller regulates the fan speed of single-phase motors from 1,5 to 10 A via phase angle control a.k.a. Triac technology. The supply voltage of 230 VAC can be turned off via the illuminated ON/OFF switch on the side of the unit. Via de potentiometer located on the front of the controller you can set the desired fan speed. Minimum speed can be adjusted via an internal trimmer and kickstart/softstart by adding/removing a jumper on the PCB of the controller. This controller is typically used to regulate the speed of AC fans or centrifugal pumps in HVAC systems. The regulator is also available with TK monitoring. This function will deactivate the motor in case of overheating. The code for this type of regulator suitable for 1,5 A is ITRS-15-DT.

This fan speed controller is used to control EC fan speed. The unregulated output can control a water valve or an electric heating element. Via the rotary knob the temperature can be set between 5 - 35°C. Fan speed is regulated manually in 5 steps, there's an Off-position and automatic mode. In automatic mode a temperature sensor PT500 is required. Choice between cooling/heating mode can be done via Modbus communication or a jumper. This controller can be connected to our SenteraWeb or a BMS-system. .
