n-ART EPS Electric Power Subsystem
PC-104 form-factor CubeSat EPS with super capacitor backup, MPPT, up to 40 W power management, and 3.3V/5V/12V regulated buses at 95% regulator efficiency.
Description
The Gumush n-ART EPS Electric Power Subsystem provides superior life cycle, depth of discharge, efficiency, and reliability compared to alternatives. Uses super capacitors for far better life-cycle and a robust thermal operating envelope compared to popular battery options. Features a user-friendly development environment with different options for development and flight models. Components are selected from previous missions and/or thoroughly tested in TVAC to ensure best performance and high reliability on orbit.
