Buy HAKRC 4255 12S 120A Powerful Regulator for High Voltage FPV Drones and Industrial UAVs
This is a single channel ESC designed to operate with voltages up to 12S (50V) and DC currents up to 120A. The model is suitable for heavy multi-rotors, cinematic drones and model aircraft where uncompromising reliability is required.
- 6S–12S LiPo voltage support for high-power, high-voltage systems.
- 100 A continuous current, up to 120 A peak for extreme loads.
- 8-layer PCB with 4oz copper to reduce heat and loss.
- Imported 80V MOS transistors and Murata capacitors for stability.
- Supports DShot150/300/600 protocols for instant response.
How the HAKRC 4255 12S 120A regulator works
The regulator converts the signal from the flight controller into control pulses for the brushless motor. The main chip operates at up to 64 MHz, and the SLM21867CA-DG driver IC enables precise switching of high-power MOSFETs. 8-layer board with 4 oz copper efficiently dissipates heat, while dual pads with plated edges prevent tear-off at high currents. You get stable operation even at peak loads.
