DC speed controller BLD-20

brushlesspotentiometerwith speed control

BLD-20 is a simple controller for DC brushless motors with Hall sensors. It is intended for small and medium size motors with current under 20Amp. This unit control motor speed (analog voltage signal, internal potentiometer or external potentiometer), direction (digital signal - by front edge or level of the signal - depends on a version of a firmware), smooth start and stop (regulated by internal potentiometer). The main parameters of controller BLD-20 Current - 20Amp Power supply - 24-48VDC Max. current - 30Amp BLD-20 inputs/outputs Start/Stop -input is intended for start or stop motor rotation - can operate as per the front edge or signal level - depends on the controller firmware. Reverse - input is intended for changing direction of motor rotation - can operate as per the front edge or signal level - depends on the controller firmware. Accel - analog input - internal potentiometer - is intended for adjusting motor acceleration and deceleration. Speed - analog input - is intended for motor speed regulation. Usage of internal potentiometer, voltage signal 0-5VDC or external potentiometer is provided. Firmware change for this model is possible at our side only. Please, ask prefered firmware before shipping.
