Product Characteristics:
This series of speed controller is a low voltage DC four-quadrant regeneration pulse width controller adopts special single-chip
intelligent control system and has rapid response speed, steady operation, reliable work status and multiple protection functions.
•
SMT technology, small size.
•
Pulse width modulation.
•
Low noise during operation, high efficiency, and low maintenance cost which better enhance the service life of DC
motor.
•
Four-quadrant regenerative operating mode.
•
Regenerative braking function.
•
It doesn’t need external reversing contactor and will not result in electric motor parts or other components overheating
or burning down.
•
Enable/ reversing terminal.
•
To realize certain functions by using simple passive switching value or transistor collector open circuit.
•
Status indicator light - Power supply indicator and over-current alarm indicator can provide the visible status of speed
controller.
•
Output current setting function (amplitude limiting).
•
Torque compensate function.
•
Double closed-loop PI regulation (current, voltage).
•
Standard analogue quantity signal control analogue quantity: 0-6V 0-10V or controlled by potentiometer
•
A broader scope of input voltage: 10-55V.
Installation Requirements:
•
Controller cannot be installed, connected or removed under charged circumstance. Otherwise accidents or severe
damages may be caused. Users should read and understand the details of “safety warning” (Page 1) before installa
tion
and obey the rules strictly.
•
Drive element is sensitive to electrostatic magnetic interference shall be kept away from environments where static is
easy to be generated; otherwise, speed controller may be damaged.
•
The driver shall be kept away from dust, high humidity environment and prevented from accidental contact. Enough
space shall be reserved around the driver for easy ventilation and regulation.
•
When fixed, the driver shall be kept from other heat sources. Guarantee that the driver works in the specified
environment temperature range.
•
The driver shall not be installed on equipment’s with extreme vibration; if not, precaution against vibration shall be
taken.
