Parker DC Motor Controller, 110 → 500 V, 1 Phase, 8 A, 360 V dc

The 514C range of isolated dc motor speed controllers provide fully regenerative (four quadrant) control of dc shunt and permanent magnet motors. They are particularly suitable for overhauling load applications or where accurately controlled braking is required.

Fully regenerative, four-quadrant motor control
Internal logic control of power supply ac contactor
Ramped speed input, auxiliary and inverted auxiliary inputs

Jumper-selectable single phase input voltage 110//120 or 220//240 or 380/415V ±10%
Linear current feedback allowing accurate torque
Zero speed or zero set point relay driver output - 24Vdc
Total setpoint output
Stall detection and trip
Field bridge suitable for UK or continental voltages
Overload capacity 150% of nominal current for 60s
Adjustable maximum current level
Adjustable maximum and minimum speed

Adjustable I.R. compensation (for armature voltage feedback speed control)
Adjustable speed stability
Independent control of speed ramp, both up and down from 0-40s
Indication of mains supply on, stall trip and overcurrent trip
Switch selectable current calibration
Switch selectable Armature/Tacho generator feedback
Buffered 0-10V output for a speed reference or meter
Buffered 0-7.5V output for a current meter (7.5V = 150%)
