L
et’s clear up some confusion surrounding tactical power supplies PP-6224C/U,
NSN 6130-01-571-2142, and PP-2953D/U, NSN 6130-01-522-3494.
Some units think the PP-2953D/U is strictly
a replacement for the PP-6224C/U. Other units
have received PP-2953D/Us but don’t know what
they’re used with. Unaware they need these power
supplies, units have turned them in.
Here’s the straight story on the two power
supplies:
The
PP-6224C/U
is the most recent power
supply under LIN P40750. The
PP-2953D/U is the
exact same power supply
with the same uses.
To sum up, the PP-6224C/U and the PP-2953D/U are manufactured on the same
assembly line. The only difference is the NSN plate put on them as they come off
the conveyor belt. Otherwise, the PP-6224C/U and the PP-2953D/U are identical in
looks and use.
What’s in a Name?
The PP-6224C/U is a major
item requiring authorization.
The PP-2953D/U is a secondary
item ordered through a funded
requisition. As stated earlier,
each has its own NSN.
Here’s the main reason: The
power supply is a high demand
item with many uses. It provides
power to operations centers,
command posts, radios, sensors
and other electronics. Having a
power supply with two NSNs
gives the Army more Fexibility
in procuring it.
PP-2953D/U
and
PP-6224C/U
are the

Actually,
there’s
another
slight
difference
between the
two power
supplies…
What’s the
difference
between the
PP-6224C/U and
PP-2953D/U?
Why
does the
Army have a
major NSN and
a secondary NSN
for the
same
item?
PP-6224C/U and PP-2953D/U
can substitute for the
following power supplies:
if you said
“they have
different
NSNs”
you
were right!
there’s
one major difFerence
between these two power supplies.

find it?
