Working voltage: 680V DC. Includes antireverse connection protection to prevent damage if the power supply is connected backward. Onboard LED indicators show standby, working, error, and other states for quick visual status checks. Module is as a bare board. If the motor current is below 5A, no forced heat dissipation is required beyond normal ventilation. If current exceeds 5A, forced cooling is required. Control options: Onboard potentiometer for analog speed control in the 0.55V range. PWM speed control interface with a frequency range of 120 kHz and a duty cycle of 10100%. Key benefits: Robust protection against reverse wiring reduces risk of damage in imperfect wiring scenarios. Wide operating voltage range simplifies power supply choices across different motor systems. Flexible control: switch between simple analog adjustment and external PWM control to suit your project workflow. Clear status indicators aid in setup, troubleshooting, and maintenance. Heat management guidance helps you plan cooling for highercurrent applications, supporting reliable operation. Typical applications and use scenarios: Robotics and automated hobby projects: drive DC motors with adjustable speed via PWM or the onboard potentiometer, using a 680V supply and benefits from reverseprotection during quickreconnects. DIY CNC or robotics axis control: integrate with microcontroller PWM outputs (120 kHz) to achieve smooth, controllable motor speed with 10100% duty cycle for precise motion profiles. Small conveyors or automation gear: use the analog 0.55V input for rapid speed trims or switch to PWM for dynamic speed changes as part of an automated process. Compatibility and integration notes: Suitable for DC motors within the 680V range. Control methods compatible with standard PWM signals and analogstyle control via the onboard potentiometer. For currents above 5A, ensure adequate cooling to maintain performance and prevent overheating.
