5 Volt Adapter Kit               

(Digital) Power to the masses!

The 5 Volt Adapter Kit is a simple kit that provided 5 volts for racks that
do nut have 5 volts available. It plugs into one socket on the power
distribution board, and as a bonus provides 2 new sockets to make up
for the one used by the adapter. The unit takes +12 volts and using a
switching regulator generates 5 volts with high efficiency.

This is an easy skill level kit. It has no tricky soldering.
