APD HV & UHV Electronic Speed Controllers
APD's HV and UHV electronic speed controllers provide high-current motor control for large UAV propulsion systems. A 32-bit ARM control architecture delivers a linear throttle response, with configurable ramp behavior for fast response or drivetrain protection.
Shared firmware functions include PWM-frequency dithering, adaptive timing advance, active phase-current demagnetization and synchronous rectification. The HV 14S is the more compact 60 V option, while the UHV 28S supports power systems up to 120 V and higher continuous and burst currents.
