18V~50VDC 0A-35A Brushless Dc Motor Driver JKBLD300 For 0 - 300w Bldc Motor
Description:
The JKBLD300 is a high performance, cost-effective 3 phase BLDC motor drive
which can provide power output 300VA max. The design is based on advanced DSP
technology and feature high torque, low noise, low vibration, PID speed loop, PID
current loop, over current protection, over load protection.
