DC motor governor

DC24/20BL-4Q02 Product introduction

RT series governor is low-voltage DC four quadrant regeneration pulse width speed regulation, adopts special single-chip microcomputer intelligent control, fast response, stable operation, reliable operation, complete protection functions, etc. Low noise, high efficiency, low maintenance, better service life of DC motor, four quadrant regenerative operation mode, regenerative braking, There is no need for external reversing contactor, which will not cause overheating or burnout of motor parts or components. When the temperature is too high, the governor will reduce its output current through the temperature judgment circuit to prevent overheating protection. If the temperature is still too high, the governor will stop output to better protect the safety of the motor and governor

Product features:

This series of speed regulators are low-voltage DC four quadrant regeneration pulse width speed regulation, using special single-chip microcomputer intelligent control, fast response, stable operation, reliable operation, complete protection functions, etc.

Adopting SMT technology and 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: 0-5V, 0-10V or potentiometer control

◆ wide input voltage range: 10-55v
