SYSTEMS CARD FILES -LSCF POWER INTERFACES

General
The left system card file (LSCF) has two power supplies. Each power supply has these two cards:
*
Preregulator

*
linear monitor.

Preregulator Cards
Each preregulator card supplies power to both linear monitor cards. Both linear monitor cards use the power from the preregulator 2 card. Preregulator 1 supplies backup power.
Linear Monitor Cards
Each linear monitor card sends power to seven linear regulators. The linear regulators are isolated from each other and send power to each member system card. The APU and left fire and overheat detection cards (FODC) receive two power inputs each.
The linear output monitor/control monitors the input and output power of the linear monitor. It sends power supply status to the ARINC signal gateway cards (ASG) on an ARINC 429 bus.
The linear output monitor/control also receives inputs from the power control switches. These switch inputs cause the linear regulators to be on or off.
