4cx10,000D/8171
chaRacteRistics
The 4CX10,000D/8171 is identical to the
4CX5000A/8170 except for its rated plate dissipa-
tion. Its increased capability, resulting in a larger
cooler, is most useful in linear applications where
plate dissipation is generally the limiting factor.
The larger cooler also allows the 4CX10,000D/8171
to be used in place of the 4CX5000A/8170 with
cooler operation at any given air flow rate.
