Systemair Thyristor control REE 050S0

Thyristor power unit REE

Stepless phase cutting controller for 1~230V/50Hz motors. It has a connection for an external control signal 0-10V or 4-20mA. The control signal can be chosen by an internal switch. Internal potentiometer to set a min. speed. On/Off Switch with control lamp. White plastic casing IP54. Several motors can be connected in parallel as long as the total current does not exceed the current range. Fans to be used with this controller require a build-in overheating protection and should be designed for thyristor speed control. It is equipped with Modbus RTU communication and provides a wide range of functionalities. For indoor use only.

NOTE: phase cutting controller can make engine noise!
