Power supplies are available for variable-torque electromagnetic brakes and clutches, such as magnetic particle and hysteresis brakes and clutches. Output current is manually controlled using a potentiometer or a 0 to 10-V control signal. Output is also scaled by a separate Span Max adjustment, so fine control, even for low current loads, is easy. The supplies offer outputs of 12-Vdc @ 1.25 A or 24 Vdc @ 0.75 A and come in enclosed or open versions, with or without an LCD ammeter.
