Features: High power no Hall brushless drive, wide voltage DC12-36V, current up to 15A, up to 500W power, compatibility with most motor (some motor may not be fully compatible, specific needs to be test by oneself, please note if you mind). It is best to use the adjustable power supply current limiting modes to test whether the actual no-load current is abnormal during the driving test, in order to avoid high-power burning of drive during the abnormal moment. Supports forward and reverse switching, potentiometer speed regulation, and has a potentiometer speed regulation function. The potentiometer can generally be used for 10-50K, or PWM 5V signal speed regulation (specific definition can be found in the introduction diagram). Exquisite and compact appearance, with neatly arranged components, wide ranges of applications, and easy to use. The positive and negative poles of the input power supply for drive must not be connected incorrectly. The output UVW three-phase should not be short circuited, otherwise drive will be burned, comes with an 18mm thick heat sink. When using it at high power, the actual heat generation size should be determined. If the heat generation is large, a fan should be added for forced air cooling. Specifications: Material: Printed Circuit Board Size: Approx. 63x43mm/2.48x1.69inch Wide Voltage Input: DC12-36V Current: up to 15A Power of Drive Board: up to 500W Package Includes: 1x DC12-36V Brushless without Hall Motor Driver Board note: Driver board does not come with a socket or wire, and requires self soldering with an electric soldering iron. The forward and reverse switches and speed controller potentiometers need to be prepare by oneself. The soldering iron must be grounded properly to avoid damage to drive caused by induced electricity.
