4P20 1
GENERAL
DESCRIPTION
The 4P20 is a Power-Over -Ethernet power supply that allows remote operation of
low power PC/104-PLUS stacks. The 4P20 provides a feed-through POE tap so that the
remote system can get power and Ethernet communication from a single CAT5 cable up
to 100 meters long. The 4P20 supplies 5V and limited amounts of +- 12V power to the
stack. +-12 Volt outputs can be disabled if not required.
An auxiliary power input can be used if POE is not available, or for battery backup
/ failover type applications. Output power is isolated from POE and AUX power. Power
connectors compatible with pluggable screw terminals are provided for the AUX and +5V
power. +5V and +- 12V are wired to the PC/104 and PC/104 PCI connectors.
