BRIEF DESCRIPTION
The unit provides manual speed control of voltage-controlled motors (230 V/50 Hz)
by varying the voltage supplied by adjusting the phase angle.
Suitable for wall (IP44) and built-in (IP54) mounting.
The splash-proof casing allows the unit to be used in harsh working environments.
The orange LED indicates the operating status.
The controller allows the control of several motors, as long as the total current
consumption does not exceed the current limit of the controller.
All models have an optional (non-adjustable) 230 V output.
Technical data
