SmallGEO Power

For missions with power hungry payloads, in its unmodified form, our CommSat power system can manage over 40A at a regulated 50V. 

In its standard configuration, this power system is compatible with missions incorporating deployed, sun tracking arrays.  The power system incorporates a number of main elements, including a 16 section Sequential Switching Shunt Regulator, hot redundant Battery Discharge Regulators, hot redundant Battery Charge Regulators and Power Distribution Module.  A fully redundant and majority voted Main Error Amplifier provides a centralised control to the system and regulation of the 50V bus. 

With slight modification, this system can acheive >100A at 50V.

The system is compatible with lithium ion/polymer battery technology.

Track record: GIOVE-A (GSTB-V2/A)*.
