1. This drive is a DC three-phase brushless and Hallless control board, and the motor can work normally without Hall. 2. BLDC wide voltage 5-36V high power 350W DC three-phase brushless sensorless controller, newly supports PLC 0-5V analog control speed control and forward and reverse, PWM signal control speed control, etc. 3. Full-chip technology, stable performance, with positive and negative functions 4. Wide voltage, high power, universal for large and small motors, PLC 0-5V PWM signal control Product Name: 350W Brushless and Hallless DC Motor Driver Model: ZS-X11B Working voltage: 5-36V Maximum current: 16A Maximum power: 350W Overcurrent protection: Yes Maximum speed: 1-1.5 million revolutions (conservative reference value, related to the number of motor pole pairs) Interface Description: 1. MA MB phase line output is connected to the motor 2. 5V GND motherboard comes with power supply (current does not exceed 30MA) 3. VCC GND motor main power supply (external DC power supply) 4. SC speed pulse signal output 5. Forward and reverse forward and reverse control interface (also can be connected with a three-gear switch) 6.VR speed control signal input, (through the board with 5V GND connected to 10K potentiometer voltage divider speed control can also be connected with PLC0-5V analog input speed control) 7. PWM input, external amplitude is 5V PWM signal speed regulation (when external PWM needs to unplug the potentiometer on VR) colour:Yellow Material:PCB+metal size:63 x 45 x 27mm Package Contents: 1 x Brushless and Hallless DC motor driver Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
