PRODUCT DESCRIPTION
ARTICLE CODES
e EVSS1 is an electronic speed controller which controls the speed of singlephase (230 VAC /50—60 Hz) voltage controllable electric motors. It is equipped
with Modbus RTU (RS485) communication, an alarm relay output and thermal
contacts to provide overheating protection of motors with cut-out contacts. e
EVSS controller 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.
