Figure 2-15. Functional Block Diagram of DNR-POWER-DC Module
As shown in Figure 2-15, the DNR-POWER-DC Module operates as follows:
A 9-36 VDC voltage input (Vin) from an external source is connected to the
board through a replaceable slow-blow fuse. The board monitors the input
current and passes Vin to the DNR bus as Vout.
Vout also is connected to DC/DC converters that produce 24 VDC, 3.3 VDC and
1.5 VDC output voltages, which are also placed on the DNR bus. Both 3.3 and
1.5 VDC voltages are connected to low dropout regulators that, in turn, generate
the 2.5 VDC and 1.2 VDC output voltages on the bus. The 24 VDC source is fed
to a low dropout regulator that produces 8 VDC to drive the cooling fans (through
fan controller chips).
