Parker Hannifin

Isolated control circuits, a host of user features and highly linear control loops make the Parker 512C analog DC speed controller ideal for low-power single or multi-motor applications.

Designed for single-phase operation, the 512C provides speed or torque control of DC motors with permanent magnets or separate excitation. Typical applications - centrifugal pumps and fans, extruders and mixers, small paper converting machines.

From 4 to 32A, DC512C 2-quadrant analog drives are ideal for low-power single or multi-motor applications requiring speed or torque control of permanent magnet or separately excited DC motors.
