With hundreds of units sold and now in its 3rd Generation, the Clyde Space EPS range offers all the experience and heritage acquired over countless missions.

Our 3G EPS motherboard is designed to support 2U and 3U CubeSats with body-mounted solar panels. For higher-power missions a daughterboard with additional Battery Charge Regulators (BCRs) can be attached to provide our FlexU EPS, supporting additional solar panels with minimal additional volume occupation.

Our EPS performs all the main functionalities of power generation and protection using analogue components. Each power generation section is self-sufficient and does not require support from any other section within the EPS, and the redundant solid-state isolation switches make it more reliable during launch operations. These features make our EPS the most robust solution in the CubeSat market. 

It employs Maximum Power Point Tracking providing a highly-efficient battery charge mechanism, that maximizes the power generation from the CubeSat solar arrays while employing taper current to increase the lifetime of the battery.

The Power Conditioning Modules provide three regulated output buses (3.3V, 5V and 12V) and an unregulated battery bus with up to 90% efficiency for the regulated buses, while providing battery over-current and under-voltage protections. The integrated Power Distribution Module will allow the safe integration of different subsystems using Latching Current Limiters.

KEY FEATURES

  • All the power converters required for a CubeSat mission are integrated within a single PC104 card.
  • Maximum Power Point Tracking employing analogue discrete components.
  • It features all the protections required for battery charge and discharge.
  • It now contains a Power Distribution Module with 10 Latching Current Limiters.
