MAGPOWR DFC-90

Product overview
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.
Follower arm/
dancer options
The DFC-90 is factory adjusted to provide full reverse current
with 0 VDC input. If some other current is desired with 0 VDC
input, the minimum current potentiometer may be adjusted by
cutting out the hole shown on the label and then using a trimpot
adjustment tool.
Modifying this setting will cause the clutch/brake drag torque to
be higher than expected and is not recommended.
