Introduction
The MAGPOWR Model DFC-90 is a complete solution for follower arm or dancer control applications. The DFC-90
provides a 90 vdc current regulated output to control electromagnetic clutches and brakes. The DFC-90 also
provides a small reverse current to minimize the drag torque of the clutch / brake.
The Model DFC-90 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.
Connections are provided for an external 1 madc current meter. The meter display will indicate clutch / brake
output current as a percentage of the output range selected.
The control circuits are electrically isolated from the power circuits.

Installation
The DFC-90 is intended for installation on a vertical panel using a DIN 35 rail with the wiring terminals facing down.
Figure 1 shows the enclosure dimensions.
Wiring to and from the DFC-90 must be done with double or reinforced insulation or protective screening which
provides protective separation. All wiring should comply with the essential requirements of the appropriate
standard(s) and is the responsibility of the installer.
Route control signal wiring away from AC wiring. Connect shields of shielded cable to the terminals indicated as
“SHIELD”. Maximum shield length and maximum length of wires outside of the shield is 3 in. (75 mm).
