HOBBYWING XRotor Pro-H300A-24S-BLDC-RTF -HW-H-IPC-V3

Product overview

The HOBBYWING XRotor Pro-H300A-24S-BLDC-RTF -HW-H-IPC-V3 is an industrial electronic speed controller for unmanned aircraft, with a control program dedicated to multirotor propulsion. It uses BLDC square-wave drive technology and supports CAN digital throttle and PWM throttle modes. Its operating voltage range is 36–110 V, and it has no built-in BEC. CAN communication supports real-time monitoring of throttle input and output, motor speed, bus current, bus voltage, capacitor temperature, MOS temperature and controller status. Built-in memory records operating data for a black-box function.

The controller has nano-coating with an IP55 protection rating; IP67 protection and CAN+485 dual-input throttle are customization options. Its propeller-positioning function requires a HOBBYWING motor with a magnetic encoding board, a DataLink data box, dedicated DataLink software, a dedicated parameter configuration file and a USB-TTL module. The optional DataLink data box also supports computer-based firmware upgrades, while another upgrade method uses a flight controller. PWM throttle signals can have refresh rates of 50–500 Hz, with a fixed pulse-width range of 1100–1940 microseconds that cannot be calibrated.

The controller must not operate at ambient temperatures above 65°C and has neither low-voltage protection nor overheat protection. It sends a warning through the data interface above 110°C; controller temperatures above 130°C may damage electronic components, requiring immediate landing or reduced throttle. Voltage below 36 V can cause abnormal operation and requires immediate landing. Separate protection functions address failed starts, motor stalls, abnormal instantaneous current exceeding 1400 A and throttle-signal loss. Loss of the throttle signal immediately stops output, and normal operation resumes when the signal returns.
