The MVS automatically controls the speed of single phase voltage controllable electric motors (230 Vac - 50 Hz) with a 0-10 Vdc or 20 mA control signal (standard). This makes it possible to control these motors automatically with an external PD-controller, on remote with a potentiometer, or a microprocessor with analogue output. They are over voltage protected by a varistor and have a built in over current fuse.
These controllers are designed to be built in on DIN-rail in control panels or switchboards. To power on, an external switch is needed. A supplementary terminal block is foreseen to branch off 230 Vac not controlled for 3-wire motor connection, a telltale or to control a valve or damper.
There are two working modes, internally selectable: ‘hard’ start or normal start.
