KDEXF-UAS55HVC - KDE Direct - Datasheet.Directory

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.

The series is tuned and optimized for the KDE Direct XF Multi-Rotor Brushless Motor Series , for simple plug-and-play operation. No additional

throttle calibration is required for most applications and settings are factory programmed.

ESCs include 200�C, 13 AWG silicone-wire power leads and 14 AWG silicone-wire motor leads with dual ?4.0mm and ?3.5mm 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.
