AC motor 3 A | variable speed control

The EVS-1-30-DM electronic speed controller provides automatic speed control of single-phase voltage-controllable motors (230 VAC / 50—60 Hz). It is equipped with with Modbus RTU communication and offers remote control options, adjustable off level, and min. and max. output voltage settings. The maximum current is 3 A. The integrated ON-OFF switch and digital input enable motor control. Precise adjustments are possible with internal trimmers and Modbus RTU. Tthe supply voltage is 230 VAC.

The MTV-1-010-NA potentiometer is a practical device designed to generate a continuous variable signal for the remote control of various HVAC equipment. This straightforward potentiometer plays a crucial role in regulating EC fans, damper actuators, AC fan speed controllers (EVS or MVS series), or frequency inverters (FI-E series). Operated with a 230 VAC supply voltage, the MTV-1-010-NA provides a reliable output voltage range of 0-10 VDC. Its primary function is to offer precise control, allowing you to adjust the control signal according to the position of the rotary knob. This makes it a valuable component in scenarios where remote control of HVAC equipment is essential. A notable feature of the MTV-1-010-NA is its intentional lack of an OFF position. In situations where maintaining a minimum air supply is technically or legally required, this potentiometer ensures that the control signal never reaches 0 V. Even when the rotary knob is turned to the minimum position (counterclockwise), the control signal remains at the minimum value, approaching 0 VDC. In combination with speed controllers with analog input, this unique characteristic addresses specific applications where continuous operation is necessary. The MTV is suitable for both inset mounting (IP44) and surface mounting (IP54), providing installation flexibility to meet your specific requirements.
