Standard potentiometer or hall throttle (0.8–4.2V), joystick mode, direct PWM input (0–95%), or RC PWM receiver input 1.5ms ±1ms. Fits any installation out of the box.
Captures kinetic energy back into the battery during braking. Essential for EV conversions and forklifts where efficiency matters. 2-quadrant operation in one direction.
18 kHz switching frequency for whisper-quiet operation. Precise 0–98% duty cycle control with adjustable acceleration ramp from 0 to 40 seconds.
Adjustable normal current limit from 0–50A, with 70A peak capacity. Protects both motor and controller from overload, extending system lifespan significantly.
Completely controllable via TX/RX serial connector with extended parameter access. Integrate directly with PLCs, microcontrollers, Raspberry Pi, Arduino, and more.
Just 65 × 76 × 28 mm and 100 g without heatsink. M6 high-current connections on all power terminals. Designed for tight installations in EVs, boats, and industrial machinery.
