not shown in the type designation: input and output filter, inhibit,
sense lines, current sharing, Out OK signal, LED indicators, and
test sockets (not 48Q models).
Example: CQ2540-9B1G: DC-DC converter, input voltage
range 33.6 to 75 V, double-output model, each
output providing 15 V/3.3 A, equipped with a heat
sink, operating ambient temperature TA = –40 to
71 °C, RoHS-compliant for all six substances.
Note: 48Q models are designed according to Telecom standards
ETS 300132-2 and EN 41003. Vi min is 38.4 V such limiting the
input current Ii to 150% of Ii nom
.
Note: All models have the following auxiliary functions, which are
