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
Features of 512C and 514C Range Speed Controllers
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%)
