regulator for electromagnetic powder brakes
LEO is a microprocessor controlled digital current regulator that can be programmed by using the three buttons on the front of the board. It can be used with the closed loop regulation and a tension controller (such as T-one, MW90 or PLC) which guarantees web tension stability. When using an open loop (with sonar, potentiometer or any other 0-10 VDC analogical input) LEO guarantees brake/clutch torque stability irrespective of variations in the condition of the brake (wear/temperature). The device can supply a negative output current in order to cancel any residual magnetism and is suitable for use at low torque applications without limitations.
