4.10.5.10. Dual Diode Assembly (94-100004)
The purpose of these dual diode assemblies is to allow two DC voltage sources to be combined, so
that the main DC rail within the equipment can be sourced from either a mains driven PSU, or
externally through an XLR connector or from dual mains driven PSUs . They are very heavy-duty
diodes and they prevent any reverse current from flowing back to their source or the alternative
supply rail. Combining diodes such as these will also be used if the equipment is to be powered from
external back-up batteries.
4.10.5.11. 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.
