19.3.3.10. 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.
19.3.3.11. DC/DC Converter 96-200047
96-200047 is an O.E.M. high power device with a wide input range and 12.5 amp @ 12V (150Watts)
output capability used to derive a 12V fixed voltage power supply rail from a higher voltage supply, in
this case 12V. In the event of failure this unit should not be repaired, only replaced.
