Thanks to our experience with European academic projects ( 3U, 1U nano-satellites) ASED can provide custom tailored REDUNDANT Electrical Power Subsystem made of commercial available parts (COTS). The system can be user tailored in shape of a 1 -3U size PCB or in the two PCBs – 1U size.
Our EPS solution includes:
- Battery charging with MPPT (Over current , over voltage protected)
- Power Distribution Unit with LCLs
- 12 V Main bus (30Watts continuous, LCL protected )
- 3,3 – 5V DC output, 2 x 2A (Main,Redundant ), LCL Protected.
- User defined output (6 – 1,8V*, LCL protected)
- User defined connector or standard PC104 connector
Each output has an over voltage protection and over current protection. In case of any events like over-current switch-off or SEE disturbance the system is self re-triggered after defined period of time. No user action needed to recover the system.
Our EPS provide a digital telemetry data via I2C interface ( Solar Array Voltage, Battery current, Battery Voltage, EPS Temperature). Binary outputs status are also available ( charging, user predefined alarm levels).
Our system is fully redundant and works in stand-alone mode. Each part of the system including internal supply is redundant and carefully designed with a Single Point Failure Free approach.
- The Essence of Pure Hardware design with SPF approach
- No software, No firmware
- Redundant outputs
- Redundant Battery
- Nanoracks/NASA compilant
