The 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 2, 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. This unit also includes reverse current circuitry as a standard feature, thus allowing greater controllability in the lowest torque range of the clutch or brake being operated. 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. With 115 vac input, either power amplifier will provide a 3.6 to 90 VDC, current regulated output to accurately control a 90 VDC brake or clutch. With a 24 VDC input, the PA-2 can also provide a 1.2 to 24 VDC, current regulated output to accurately control a 24 VDC unit. Specifications: PA-2: With 115 VAC input: -3.6 to 90 VDC, with selectable current ranges 1/8, 1/4, 1/2 amp maximum With 24 VDC input: -1.2 to 24 VDC, with selectable current ranges 1/8, 1/4, 1/2, 1, 2 amp maximum
