21.3.2.10. DC/DC Converter 13-003412
13-003412 is based upon an O.E.M. DC/DC Converter module with a wide input range and and is
used to derive a 12V fixed voltage power supply rail from a higher voltage supply, in this case 24V. In
the event of failure this unit should not be repaired, only replaced.
