DC Servo Controllers

Sprint Electric, in cooperation with its US partner Bardac, introduces a new range of DC servo controllers. The XLV is a miniature, fast response DC motor speed controller.The extended XLV range is designed for use with permanent magnet brushed DC servo motors rated from 4 to 12 Amps, offered in a compact, easy to use DIN rail mounting package. The XLV range of controllers are suitable for use on DC supplies up to 48 V and can be used in either current (torque) or speed control modes. For highly dynamic applications, a shaft-mounted DC tacho-generator is recommended for speed feedback, but in less demanding applications, armature voltage feedback (Avf) can be used. The reference signal for both current and speed control can be either bipolar (+/-10 V) or unipolar (0 to 10 V). Motor speed can be controlled in both forward and reverse directions.

An adjustable current limit and fast-acting current control loop protect the controller and motor from sustained overloads. The 400 XLV model for motors rated up to 4 Amps, the 800 XLV for 8 Amps and the 1200 XLV for 12 Amps are additions to the miniature 200 XLV model. Despite measuring just 60 mm wide, 120 mm high and 105 mm deep for the 400 and 800 models, and 69 mm wide for the 1200 model, the XLV is a genuine four quadrant drive that can motor and brake in both directions of rotation to offer outstanding control of motor speed and torque.
