Introducting HVPDU
The HVPDU is a high voltage power distribution solution developed by Ocellott to manage high voltage systems for eVTOL, designed to ensure safety, flexibility, and efficiency in high voltage applications for the whole product life cycle.
With advanced protection algorithms and programmable logic, the HVPDU adapts to various power supply conditions. It supports FPGA or DSP-based control, offering flexibility and reliability.
Built with advanced composite materials, the HVPDU meets IEC 60664-1 standards for creepage and clearance. It features aerospace-grade connectors (according to MIL-DTL) and is designed for passive cooling, depending on customer requirements.
