Electrical Power System

The Electrical Power System (EPS) from Data Patterns is a flight qualified, power supply module designed for Micro/Nano/Cube satellite platforms. The EPS module is designed to be interfaced to two solar panels with Advanced Triple Junction (ATJ)/ Ultra Triple Junction (UTJ) type solar cells and one external supply terminal for battery charging. Ideal diodes are provided in each input to isolate and block the reverse current during failure of any one of the solar panels.

The module can accept a maximum input voltage of 14V from each panel and also has a feature to monitor the voltage and current of solar panels. The module has a battery charge/discharge regulator, voltage regulators and distribution electronics.
