Product description
The Control Techniques MP105A4R is a DC drive of the Mentor MP series in a regenerative four-quadrant version. This operating mode covers motoring operation and regenerative braking in both directions of rotation. The power rating is characterised by an armature current of 105 A. For the field circuit, the maximum current is 8 A; armature and field current refer to separate electrical circuits of the DC motor. The manufacturer's data sheet states a motor power of 37.5 kW. Mechanically, the unit is assigned to frame size 1B. The device has a three-phase mains connection and is specified for a mains frequency range of 45 to 65 Hz. The auxiliary voltage range is 208 to 480 V. The control connections comprise six digital inputs and three digital outputs. In addition, there are three analogue inputs and two analogue outputs. Discrete control signals and analogue signal paths are therefore listed separately. The integrated field controller is part of the standard equipment of the Mentor MP series. The heat sink is cooled by demand-controlled fans. The specified enclosure protection rating is IP20. The complete model identifier for the quotation with shipping from Germany to the United States and other international destinations is MP105A4R and designates the regenerative version listed here. The external dimensions are 293 mm width, 444 mm height and 251 mm depth. These figures describe the size of the unit; connection space and installation situation are separate dimensions. The specified weight is 12.6 kg, although the reference basis is not stated in detail. The combination of frame size 1B, 105 A armature current and four-quadrant operation distinguishes this version within the Mentor MP range.
