DC governor
DC24RT15BLProduct 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
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.
◆ pulse width modulation
Low noise, high efficiency, low maintenance and better service life of DC motor
◆ four quadrant regeneration operation mode
◆ regenerative braking
No external reversing contactor is required, which will not cause overheating or burning of motor parts or components
◆ enabling / braking / reversing terminal
One of the functions can be realized by a simple passive switch or transistor collector open circuit
◆ status indicator
Power supply indication and various fault alarm indications can provide the visual state of the governor
◆ forward / reverse speed can be set separately
◆ output current setting function
◆ brake current setting function
◆ torque compensation function
◆ double closed loop PI regulation (current, voltage)
◆ standard analog signal control
Analog quantity: 0-5V or potentiometer control
◆ overvoltage / undervoltage protection function
◆ overheat protection function
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.
