All 514

The range of 514C Series regenerative converters, with single phase AC supply,
offers full four-quadrant control of wound field or permanent magnet DC motors.
It is ideal for applications requiring accurate braking of high-inertia loads or their
fast and precise deceleration. 514C Series and its non-regenerative version 512C
have been designed to offer the ideal solution for speed control of single and multimotor applications.
