Potentiometer for EC fan | dry contact output
Product description
Introducing the MTV-1-010-CP Potentiometer – a straightforward yet effective solution for manual control of EC fans, AC fan speed controllers, or damper actuators. With a power supply of 230 VAC, this potentiometer offers a continuous variable output signal, easily adjusted via the rotary knob for seamless ventilation control.
The MTV-1-010-CP simplifies your system's operation with a dry contact for remote ON-OFF switching, adding practicality to your ventilation setup. Its jumper feature provides selectable output options, allowing you to choose between 1-10 VDC, 2-20 mA, or 10-100% PWM output types based on your specific requirements.
Fine-tune your ventilation control effortlessly. Two internal trimmers enable you to adjust the minimum (Vmin) and maximum (Vmax) output values within the ranges of 10-70% and 30-100%, respectively. This ensures precise control over your ventilation system without unnecessary complexity.
The MTV-1-010-CP is designed for durability, featuring a splash-proof enclosure suitable for both inset (IP44) and surface (IP54) mounting. This ensures reliability in diverse environmental conditions.
Enhancing its practicality, the potentiometer includes a built-in switch with an on/off function, using the dry contact at the leftmost position. This functionality makes it possible to swich on/off external equipment.
Additional specifications and description
0 - 10 V potentiometer
A potentiometer generates a continuously variable signal to control other devices (i.e. 0 - 10 V). This control signal increases or decreases according to the position of the rotary knob. The control signal is typically used to remotely 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). For example, the potentiometer can be installed in the study, while the fan speed controller is located in a technical room or an electrical cabinet.
Adjustable minimum and maximum levels
Some EC motors cannot handle control signals that are too low. Sometimes a fan is over-dimensioned or too powerful. For such applications, the upper and lower limits of this potentiometer output can be adjusted via trimmers. The minimum output value can be adjusted via the Vmin trimmer (1). The maximum output value can be adjusted via the Vmax trimmer (2). The minimum values can be adjusted within 1—7 VDC / 2—14 mA / 10—70 % PWM, and the maximum values are within 3—10 VDC / 6—20 mA / 30—100 % PWM.
230 VAC supply voltage
This potentiometer operates with a supply voltage of 230 VAC and produces a three types of stepless output signal: 0—10 VDC, 0—20 mA or 0—100 % PWM. The 230 VAC supply voltage is common in many electrical systems, and you simple to connect your MTV directly to the mains without the need for a power supply module.
A 0—10 VDC control signal is the most common method used in the HVAC industry for controlling various parameters, such as EC fan speed, valve positions or other components in electronic systems. The 0—10 VDC control signal corresponds to a range of desired settings. For example, if you have a system that requires modulation or adjustment, this control signal type can be interpreted to represent a range from 0% to 100% of the desired parameter. A 0 V signal might indicate the minimum setting, while a 10 V signal could represent the maximum setting.
Different output types selection
The output type of this potentiometer can be selected via the jumper (3) included in the set: 0—10 V, 0—20 mA or 0—100 % PWM.
Enclosure
The potentiometer features a wall-mounted housing constructed from durable ASA plastic in a cream color (RAL 9010). The choice of material ensures UV resistance and offers protection against dust, water splashes and impacts. The design allows for versatile installation on any type of wall or panel as the enclosure accommodates both inset and surface mounting options, providing flexibility in installation. The protection class is IP44 for inset mounting and IP54 for surface mounting, attesting to its reliability in safeguarding the internal components against environmental elements.
For inset mounting, the enclosure design aligns with standard European wall boxes, ensuring a seamless fit. The overall solidity of the enclosure makes it suitable for mounting in various types of walls.
