EPS I Power Module

The EnduroSat Electric Power System (EPS I) has the highest power efficiency in its class. It supports a wide range of outputs making it a versatile solution fully compliant with the CubeSat standard. Our EPS module has flight heritage, including the ISS-level requirements.

Features:

  • Three Solar Panel Channels (one for each CubeSat axis: x, y and z)
  • Six connectors for the solar panels
  • Integrated blocking diode for each solar panel connector
  • Stackable battery packs up to 8A
  • Two deployment and one Remove Before Flight (RBF) switches can be connected
  • Six general purpose outputs for shutdown/reset of external modules
  • Latch-up protected 3.3V and 5V outputs

Includes:

  • USB debug & battery charger
  • Packed in a custom box
  • 5 hours of engineering support
  • Full warranty
  • Technical information (Datasheet)

Qualification:

Space qualification tests are performed on the Qualification Engineering Model. Qualification test levels and duration will follow the ESA standard ECSS-E-ST-10-03C and GEVS: GSFC-STD-7000A.
