Typical application : 

BLD4820TC is widely used in textile equipment, medical equipment, food machinery and equipment, power tool, garden machine, smart-home device and other electrical automation control fields.

Product overview :

BLD4820TC is applied to the speed control of brushless DC hall motor. Its biggest advantage is that it can always control the motor to maintain the maximum torque at low speed. In addition, this product has advantages of diversified speed adjustment mode, wide speed adjustment range, complete functions, hardware and software full protection, etc.

Diversified speed adjustment mode: 

Provide potentiometer speed control, voltage speed control, external PWM speed control, CAN speed control, etc. Wide speed adjustment range: support speed adjustment within the range of 200~20000 rpm(Two-pole motor); Complete functions: with functions of enable, positive and negative turning, braking, motor speed signal output, alarm output, etc. Hardware and software full protection: with functions of blocking protection, over-voltage protection, under-voltage protection, over-current protection, over-temperature protection, the hall signal fault alarm, etc.
