Opto-isolated electronic speed controller for multi-rotor UAS with 95 A continuous and 165 A peak current from 3S to 12S supplies. The anodized aluminum case is rated IP56 and the unit weighs 78 g without wires and connectors.
The KDE-UAS95HVC is a 95 A high-voltage electronic speed controller from KDE Direct for brushless motors on electric multi-rotor unmanned aircraft. It belongs to the maker's UAS HVC series and accepts supplies from 3S LiPo (11.1 V) to 12S LiHV (52.2 V), so it covers small commercial multirotors as well as heavier platforms that run on high-voltage packs.
The controller is rated for 95 A continuous current (180 s) and 165 A peak current (5 s). That corresponds to 4,220 W continuous and 7,325 W peak power. The maker specifies these continuous figures with consistent airflow of 5 mph or more across the heatsink, and the unit limits maximum RPM when its internal temperature rises above 95 °C. Maximum electrical speed is 360,000 rpm for a 2-pole motor, with dynamic advance timing of 22° to 30°.
Control uses a PWM throttle signal with automatic recognition of the signal rate, refreshed at 600 Hz (adaptive between 50 and 600 Hz). The input is opto-isolated and the unit has no internal BEC, which keeps the flight controller electrically separate from the motor supply. Firmware features include regenerative braking, temperature-controlled synchronous rectification (active freewheeling), dynamic timing and startup power, motor synchronization and an anti-spark circuit that protects connectors at power-up. Parameters are set with the KDE Direct Device Manager adapter through the programming lead.
The case is machined aluminum 6061-T6 with a black anodized finish and carries an IP56 rating for all-weather operation. The body measures 82 × 37 × 15.25 mm and weighs 78 g, or 114 g with wires and bullet connectors. It ships with 12 AWG power leads, 13 AWG motor leads, 22 AWG control and programming leads with 3-wire JR connectors, and two pairs of 24K bullet connectors (4.0 mm and 6.5 mm). The maker lists the power leads at 200 °C and notes that DC leads longer than 12 inches need extra capacitance.
The maker lists the product as not NDAA compliant. The maker positions the series for commercial and industrial UAS applications, and provides a design geometry file and a specification sheet for installation planning.
