NEW KDE DIRECT 55A ESC'S FOR DRONE
Description : 13 May, 2023
6 New KDE Direct 55A ESC's , KDEXF-UAS55 for Quadcopter, Hexacopter or Drone. They have never been used or installed, still in original box. You won't find a better quality ESC then KDE. $750 for all.
Description: The UAS series patible with 2S LiPo - 8S LiHV power systems - allowing for the next level of performance and efficiency for your sUAS and Multi-Rotor applications.
New production version 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 new series es 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 mands 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 mands. 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 mands and UAS Brushless Motor response capability.
ESCs now include 200°C, 13 AWG silicone-wire power leads and 15 AWG silicone-wire motor leads with dual ф4.0mm (KDEXF-BC40) and ф3.5mm (KDEXF-BC35) 24K matching Bullet Connectors.
Specifications: Refresh Rate 600 Hz (50 - 600Hz Adaptive) Maximum Peak Current 95 A (5 s) Maximum Peak Power 2,810 W (5 s) Maximum Continuous Current* 55 A (180 s) Maximum Continuous Power* 1,630 W (180 s) Maximum Efficiency > 98% Voltage Range 7.4 V (2S LiPo) - 34.8 V (8S LiHV) Internal BEC None (Opto-Isolation) Maximum RPM 360,000 rpm (2-Pole) PWM Rate Adaptive Dynamic Algorithm Advance Timing 22° - 30° Dynamic Algorithm PCB Size 25 mm (W) x 58 mm (L) ESC Weight 32 g (60 g with Wires/Bullets) Power Leads 13 AWG, 200°C Motor Leads 15 AWG, 200°C ESC Control Lead 22 AWG, 3-Wire JR (W-R-B) ESC Programming Lead 22 AWG, 3-Wire JR (O-R-B) Power Connects ф3.5 / ф4.0 mm Matched Pair Motor Connects ф3.5 mm Female
