0-10 V Potentiometer | OFF-position | 24 V supply


Product description

0-10 V potentiometer with OFF-position. It controls EC fans or damper actuators. It can also remotely control AC fan speed controllers or frequency inverters. The supply voltage is 24 VAC or 24 VDC. The continuous variable output signal can be set via a rotary knob. The rotary knob has an OFF-position: when the rotary knob is turned completely counter clockwise, the control signal will be disabled. The high and low levels are adjustable via two trimmers: Low level between 0-7 VDC and high level between 3-10 VDC. The splash-proof enclosure allows inset mounting (IP44) or surface mounting (IP54).

Additional specifications and description

 
What is the purpose of a 0-10V potentiometer?
The control signal (output of the potentiometer) increases or decreases according to the position of the rotary knob. This control signal can directly control EC fans or damper actuators. It can also remotely control AC fan speed controllers (EVS or MVS series) or frequency inverters (FI-E series). E.g. the potentiometer can be installed in the living room while the fan speed controller is located in a technical room or electrical cabinet.
 
24 V power supply
24 VDC or 24 VAC are commonly used supply voltages in the HVAC industry. Sentera offers a complete range of high-quality 24 V power supplies.
 
Adjustable minimum and maximum level
For some applications, it is desirable to adjust the low limit and the high limit of the control signal. Some EC motors or damper actuators cannot handle control signals that are too low. The low limit of the control signal can be adjusted via a built-in trimmer. Sometimes, a fan is overdimensioned. In that case, the high limit of the control signal can be reduced via the maximum trimmer. This will limit the maximum fan speed.
 
What are the limits of the control signal?
The minimum value of the control signal can be set between 0 and 7 VDC. The maximum value of the control signal can be set between 3 and 10 VDC. Always check that the applied limits result in a control signal that complies with the specifications of the connected device.
E.g. if the supplied voltage is 15 VDC and the high limit is set to 100 %, the connected device must be able to handle a control signal up to 15 VDC.
 
OFF position
The rotary knob has an OFF-position: when the rotary knob is turned completely counter clockwise, the control signal will be disabled. When the rotary knob is turned clockwise, it clicks out of the OFF-position. The control signal will immediately jump to its low limit level. In case an EC fan is connected to the potentiometer, it willstart and accelerate towards low speed. The EC fan can never be enabled at aspeed lower than the selected minimum speed.
