CROWN CLIP Series Sockets (Continued)
CROWN CLIP Sockets II Connector Electrical Performance
The graphs below show the electrical performance of
CROWN CLIP II sockets in terms of temperature rise and
voltage drop at currents from 150 Amps to 350 Amps. The
set up used for the test had samples of six CROWN CLIP
sockets mounted on a .25" x 1.75" x 6.0" bus bar, mating
with 1.0" long by .125" thick nickel plated blades con-
nected in series using 1/0 AWG wire.
Dual pole, float-mount
socket design delivers
300 Amp current capability
plus current interruption.
Float-mount design
provides alignment for
blind-mating of rack-
mounted power supply
units. The dual pole con-
tact design allows mating
to a two pole laminated
bus bar or double sided
PCB tab, adding design
flexibility by providing feed
and return using a single
socket. Current interruption
ratings are 100 A at 48 V
and 200 A at 42 V, both
using a gold plated,
solid tab.
