INTENDED AREA OF USE
e EVS-1-XX-DM is an electronic speed controller which controls the speed of
single-phase voltage controllable electric motors. It is equipped with Modbus RTU
communication and provides a wide range of functionalities: remote control options,
adjustable off level, min. and max. output voltage settings, and time-limited motor
operation initiated by a logic or switch signal.
