Module Description
The MicroNet expansion chassis may use either single or redundant power supplies. A motherboard
located on the back of the chassis allows the two power supplies to form a redundant power system
providing two separately regulated, 24 Vdc, 12 A outputs; two separately regulated, 5 Vdc, 20 A outputs;
and two separately regulated, 5 Vdc precharge outputs to the control. Power output regulation, including
line, load, and temperature effects, is less than ±5%.
POWER SUPPLY FAULT LED
—This red LED turns on when one of the supply’s three power converters
has shut down or one or more of the supply levels is below internally specified levels.
If this LED is on,check for a short circuit on external devices connected to the control’s power supply.
When redundant power supplies are running, current sharing circuitry balances the load to reduce heat
and improve the reliability of the power supplies.
