Working voltage:6-60V (limit 60V with margin for use) Working current:rated16A, peak 20A Power:Rated 200-300W, peak 350W (with allowance for enhanced heat dissipation when using high power) Overcurrent protection:Yes INTERFACE DESCRIPTION 1. MA MB MC phase line output connected to motor 2. The 5V GND motherboard comes with a 5V power supply (the external power supply current can not exceed 50MA) 3. VCC GND main power supply (external DC power supply) 4. SC speed pulse signal output (only interface reserved, no technical support provided) 5. DIR direction control forward and reverse control interface (effective at low levels and can be connected to external switches to ground) 6. STOP stop control interface (low level effective for grounding external switch) 7. Brake control brake control interface (high level effective for 5V external switch) 8. Speed regulation control speed regulation signal input (board integrated potentiometer speed regulation can also be externally connected with 0-5V analog PWM dual signal input speed regulation) 9. Ha Hb Hc+5V GND Hall signal power supply input interface, TZT, generally motors with Hall have corresponding 5 wires Product Name:350W Brushless Hall DC Motor Driver Model:ZS-X11H V2 Colour:As Shown Material:Metal+Plastic Package Contents: 3 set x motor controller
