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.
