DC motor governor

Dc24-48rt10bl product introduction

一、Product features：

The DC governor is a low-voltage four quadrant regenerative pulse width speed regulator, which is controlled by a special single-chip microcomputer. It has the advantages of fast response, stable operation, reliable operation and complete protection function.

◆ SMT technology, small volume

◆ pulse width modulation

Motor running noise, high efficiency, low maintenance, better improve the service life of DC motor.

◆ four quadrant regeneration operation mode

◆ regenerative braking function

No external reversing contactor is required, which will not cause overheating or burning of motor parts or components

◆ enabling / reversing terminal

One of the functions can be realized by a simple passive switch or transistor collector open circuit.

◆ status indicator

Power indication and over-current alarm indication can provide the visual state of the governor.

◆ output current setting function (limiting)

◆ torque compensation function

◆ double closed loop PI regulation (current, voltage)

◆ standard analog signal control

Analog quantity: 0-10V or potentiometer control

◆ wide input voltage range: 20-55v
