KDE XF 55A HVC OPTO Brushless Multirotor ESC

KDE XF 55 HVC Multi Rotor OPTO ESC

Up to 12s LiPo, metal cased


The new UAS HVC series brings to life the next-generation of technology for UAS and Multi-Rotor operation; including an all-Aluminum 6061-T6 case for cool-running temperatures and rugged-construction, allowing the ESCs to be used in a wide-range of harsh environments and commercial/industrial applications.  The new series also comes pre-loaded with the latest production firmware, including these new, market-leading technologies:

  • Regenerative Braking – active braking during motor deceleration phase, providing instantaneous response to the flight controller commands and matched-response to acceleration profiles (less “float” during flight).
  • Temperature-Controlled Synchronous Rectification – new proprietary algorithm for smooth-running motors at low-throttle and improved, faster response under high-peak loads; all while significantly increasing flight-time efficiency and reducing operating temperatures (also termed "active-freewheeling").
  • Dynamic Timing and Startup Power – optimally-tuned for smooth and precision-controlled startup throughout the full-range of XF UAS Brushless Motors (no hesitation, stuttering, or response lag).
  • Increased Drive and Throttle Frequency Resolution – high-accuracy, linear throttle response throughout full-range of operation control.
  • Motor Synchronization – factory-calibrated ESCs for consistent throttle control and frequency-matched start-up protocols.

The UAS HVC series is compatible with 3S - 12S LiPo (55V Max) power systems - allowing for the next level of performance and efficiency for your UAS and Multi-Rotor applications.  In addition, the UAS HVC series includes active anti-spark circuitry, protecting the integrity and life-span of the critical connectors upon each initial plug-in and system power-up.

ESCs include 200°C, 13 AWG silicone-wire power leads and 14 AWG silicone-wire motor leads with dual ф4.0mm and ф3.5mm 24K matching Bullet Connectors.

*: ESC requires consistent airflow (5 mph or greater) across the heatsink to maintain maximum continuous current and power ratings during operation, specified at full-load condition (100% throttle). Increasing airflow or adding additional cooling can further increase the capabilities of the controller and extend the lifespan of the critical internal components.
