Magpowr DFC-A
Need control of a dancer, follower arm or both? No problem, as MAGPOWR’s DFC-A low-cost tension controls can handle either operation mode.
Dancer Mode: The DFC-90 and DFC-A are full PID closed-loop dancer controls, controlling web tension by sensing the position of the dancer arm through a DFP or DFP-2 Position Sensor and adjusting the clutch, brake or motor control torque accordingly to maintain the dancer position set point.
Follower Arm Mode: The DFC-90 and DFC-A control web tension by compensating for measured changes in the roll diameter. Roll diameter changes are measured through the DFP or DFP-2 Position Sensor and a follower arm. An optional Stop Multiplier provides additional stopping torque to help stop large unwind rolls
- Superior control performance at an affordable price
- Enhanced dancer algorithm and tuning method for performance
- Non-interactive Core and Full Roll adjustments
- Compact enclosure requires minimal space
- Simplicity of DIN rail mounting
- UL and CE Approved for safety and electrical noise immunity
- Applications: DFC-A: Dancer or Follower Arm Control of a pneumatic brake, clutch or motor drive
