Working voltage: 6-20V (maximum 24V) Drive current: rated 30A with air cooling up to 50A Maximum power: 1000W Overcurrent protection: Yes Locked-rotor protection: Yes (current automatically reduces and operates intermittently after lock) Over-temperature protection: Yes (power reduces by 50% when overheated) Maximum speed: 224000 RPM (2 pole motor), 74000 RPM (6 pole motor), 40000 RPM (12 pole motor), 35000 RPM (14 pole motor) Precautions: 1. Reversing the positive and negative connections on the power supply may cause permanent damage to internal components. 2. Over-current protection is active during normal operation. Due to high power and current levels, do not short-circuit the output. Short circuits may result in component failure or damage. For initial testing, use low voltage and low current. Once verified, proceed with higher ratings. As this is an open PCB design, ensure proper insulation of wiring connections. Avoid touching exposed circuitry. 3. Do not operate motors that significantly exceed the driver module's specified voltage, current, or power ratings to prevent damage.
