Option -9: Extended Temperature Range
Option -9 extends the operational ambient temperature range
from –25 to 71 °C to –40 to 71 °C. The power supplies provide
full nominal output power with convection cooling. Option -9
excludes inrush current limitation by NTC.
Option E: Inrush Current Limiter
CS/DS/ES/FS/LS types may be supplemented by an electronic
circuit (option E, replacing the standard built-in NTC) to achieve
an enhanced inrush current limiting function.
Option E is
mandatory for -9 models.
CS models fitted with option E and option D6 (input voltage
monitoring) meet the standard ETS 300132-2 for 48 VDC supply
voltage. Option D6 (externally adjustable via potentiometer from
36.0 to 40.5 V) is necessary to disable the converter at low input
voltages, avoiding an excessive input current. Option D6
threshold level should be adjusted to 44.0 - 50.0 V for 60 V
nominal supply systems (refer to the description of option D). The
D output can be connected directly to the inhibit input.
Note: Subsequent switch-on cycles at startup are limited to max.
10 cycles during the first 20 seconds (cold model) and then to
max. 1 cycle every 8 seconds.
