INTRODUCTION
The MAGPOWR Model PS90 is an isolated controllable current regulator for 90 VDC magnetic
particle clutches and brakes. The PS90 also provides a small amount of reverse current to minimize
the drag torque of the clutch / brake.
The Model PS90 has four jumper selectable current ranges. Maximum outputs for the individual
ranges are 0.125, 0.25, 0.5 and 1.0 ADC. The appropriate range is determined by the current rating
of the clutch or brake to be controlled. For best torque control resolution, the lowest current range
providing sufficient current for maximum operating torque should be selected.
The PS90 accepts either a remote adjustment potentiometer, or a 0 to 10 VDC analog control signal.
Connections are provided for an external 1 mADC current meter. The meter display will indicate
output current as a percentage of the output range selected.
The control circuits are electrically isolated from the power circuits.
INSTALLATION
The PS90 is intended for installation on a vertical panel with a DIN 35 rail, with the wiring terminals
facing down. Figure 1 shows the enclosure dimensions.
