KDEXF-UAS35
35A+ Electronic Speed Controller (ESC) for Electric Multi-Rotor (sUAS) Series

(Patent Pending)
  • $58.95

Overview

ESC Programming Device: KDE Direct Device Manager Adapter

The UAS series is compatible with 2S LiPo - 8S LiHV (35V Max) power systems - allowing for the next level of performance and efficiency for your sUAS and Multi-Rotor 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 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 new KDE Direct UAS Multi-Rotor Electronic Speed Controller (ESC) is optimized for multi-rotor applications and utilize a proprietary algorithm for up to 600Hz refresh rate control and high-speed response to the flight system commands. Dynamic PWM and Motor Advance Timing algorithms are used for optimal flight performance. The series is specifically designed and optimized for the KDE Direct UAS Multi-Rotor Brushless Motor Series. For maximum stability and performance of the flight controller, the system is tuned to react almost instantaneously to the flight commands and UAS Brushless Motor response capability.

ESCs include 200°C, 14 AWG silicone-wire power leads and 15 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.
