3.6.5.10. Dual Diode Assembly (94-100004)
The purpose of these dual diode assemblies is to provide polarity protection for the DC voltage input.
They are very heavy-duty diodes and they prevent any reverse current from flowing back to their
source.
3.6.5.11.
DC/DC Converter, 24V in, 12V 5A out (96-200024)
This unit it is an O.E.M high power device with a 5 amp @ 12V (60Watts) output capability used to
derive a 12V fixed voltage power supply rail from a 24V supply. In the event of failure this unit should
not be repaired, only replaced.
