Controller

Constant current controller for magnetic particle clutches and brakes
with optional PID-controller Z2 / Z4
Magnetic particle clutches / brakes, fed by the LIEDTKE controller work independently of temperature and deliver a constant torque.
The output current is adjustable in a wide range by the constant current control, independent of resistance by the connected load.

Applications	Optional PID-Controller Z2/Z4 for:
Unwind brakes / winding Torque control Torque limiting Speed control Clutch process Start control	Tension force control Brake control torque measuring Dancer control
