- Sensorless 3-Phase BLDC Core Specs：This V3 version high-speed driver works seamlessly with 3-phase DC brushless motors without Hall sensors (no Hall required for normal operation). It delivers 300W peak power (200W-250W rated), 5-50V wide operating voltage (60V max for emergency use), and 16A rated current (25A with forced cooling). Ideal for brushless motor setups in DIY projects, small tools, and industrial automation.
- 3-Signal Speed Control & Versatile Operation：Supports 3 adjustable speed modes: PWM signal (3-5V, 1kHz-10kHz), PLC 0-5V analog input, and 1-4.2V Hall throttle input—switch modes via the on-board button with LED indicator. The driver defaults to 0-5V mode (potentiometer set to minimum for all external modes), enabling precise speed regulation for different motor applications.
- Fast Acceleration & Safe Operation Guidelines：Features quick acceleration response but note: full-throttle startup at high voltage/power may cause high inrush current—leave operating margin and avoid hard direction reversal at full speed. Braking also creates strong impact; reduce speed throttle to 50% or below before braking/ reversing to prevent damage to power transistors and chips.
- Dual Protection & Low-Voltage Testing：Equipped with overcurrent, locked-rotor (current drops automatically after stall), and over-temperature protection (power halved in overheat). For initial wiring, always test with low voltage (5-50V) and low current first; avoid high-current/high-voltage testing during troubleshooting to protect the driver module.
- User-Friendly Design & Hassle-Free Setup：All ports use durable terminal blocks for easy wiring; comes with a standard heat sink and built-in speed potentiometer. The compact size (63×45×31mm) and lightweight (75g) make it easy to install in tight spaces—simply wire correctly, power on, and the controller is ready to use for your motor projects.
