The MicroNet Plus Expansion Chassis may use either single or redundant power supplies.

Each power supply module produces three regulated outputs: 

24 V @ 12 A (max), 5 V @ 32 A (max, derated above

55 degree C external ambient temperature), and 5 V Precharge @ 3 A (max).

A motherboard located on the back of the chassis provides the 

interconnection of the three outputs from each power supply module

into three corresponding power busses: 24 V bus, 5 V bus, and 5 V precharge bus.

The 24 V and 5 V busses are load shared between the two power supply modules.

The 5 V precharge bus is not load shared.

Power output regulation at the motherboard, including line, load, and temperature effects,

is less than ±10% for the 24 V bus, +/-5% for the 5 V bus, 

and +/-10% for the 5 V Precharge bus.

The 5 V and 5 V Precharge busses are not for external use.

The 24 V bus is accessible from the motherboard for

external use (protected by 5 A fuses on the source and return lines).

When redundant power supplies are running, current sharing circuitry balances the load to reduce heat

and improve the reliability of the power supplies.
