MAGPOWR’s PA-90 and PA-2 Power Amplifiers are designed to provide the extra current required for controlling magnetic particle brakes and clutches in any tension control application. For use with DIGITRAC II, EZ-Trac, or VERSATEC, the PA-90 and PA-2 can be mounted inside the control's enclosure, and receives its control signals directly from the tension control.

The PA-90 is used to control 90 VDC brakes and clutches only, while the PA-2 can be used to control either 24 or 90 VDC units. MAGPOWR’s power amplifiers also include reverse current circuitry as a standard feature, thus allowing greater controllability in the lowest torque range of the clutch or brake being operated.
