UHV ESC

Running a 180 MHz 32-Bit processor, this unit will deliver maximum smoothness, unmatched linearity, with ultra-fast throttle response optimised for flight control. With a peak power rating of 45kW, these ESCs will have no trouble powering your craft.

The APD developed (proprietary) firmware ensures unmatched low-throttle and starting characteristics. Ultra-smooth starting and ramp-up characteristics ensure your drive-train is safe. Features include PWM-frequency dithering to avoid PWM-commutation synchronisation, adaptive motor timing advance and proprietary developed Active Phase-Current De-magnetisation (APCD). APCD along with Synchronous rectification ensure maximum ESC efficiency is achieved.

• Designed and manufactured in Australia using only the highest quality components.

• Bolt/Screw terminals for power and motor outputs, maximising mechanical reliability.

• Harwin Datamate connector for Signal and UART Telemetry output (non-isolated)

• Optional mounting bracket for both ESC and external fan.
