Picture 3-4: CDN 5500
If a DC source with remote sense is being used to simulate the battery input (i.e. supply power to the DUT) then
the sense inputs can be used to ensure that the voltage at the main source Input is accurate by compensating
for voltage drops in the lines. If a pulse 4/2b amplifier is supplied with the test system then this can also be
used as the battery input for all the other pulses. The mains Input unit is fitted with two 3.15 A / 6.3 A time-lag
fuses. This is intended to protect the internal power bus in the case of an overload condition.
The difference between the CDN 5500 and CDN 5501 is that the CDN 5501 can be upgraded with an additional
S1, S2 and S3 dropout switches. Both contain the CDN needed battery switch for during Pulse 1 testing, and
generally switching the DUT on and off.
