-9 Extended Temperature Range
Option -9 extends the operational ambient temperature
range from –25...71
°C (standard) to –40...71°C. The
power supplies provide full nominal output power with con-
vection cooling. Option -9 excludes inrush current limitation
by NTC.
E Inrush Current Limitation
CS/DS/ES types may be supplemented by an electronic
circuit (option E, replacing the standard built-in NTC) to
achieve an enhanced inrush current limiting function (not
available with AS and BS types).
If fitted with option E (inrush current limitation) together with
option D6, input voltage monitoring, the CS units meet the
CEPT/ETSI standards for 48 V DC supply voltages accord-
ing to prETS 300132-2, version 4.2, date 9312. Option D6,
externally adjustable via potentiometer, is necessary to dis-
able the converter at input voltages below actual service
voltage ranges, avoiding an excessive input current when
the
input
voltage
is
raised
slowly
according
to
prETS 300132-2. Option D6 threshold level should be ad-
justed to 36.0...40.5 V for 48 V nominal supply systems or
44.0...50.0 V for 60 V nominal supply systems (refer also to
description of option D). The D output should be connected
to the inhibit input. Please contact Power-One if applica-
tions do not permit potentiometer setting.
