-9 Extended Temperature Range
Option -9 extends the operational ambient temperature
range from –25 to 71 °C (standard) to – 40 to 71 °C. The
power supplies provide full nominal output power with
convection cooling. Option -9 excludes inrush current
limitation by NTC.
E Inrush Current Limitation
The converters may be supplemented by an electronic
circuit replacing the standard built-in NTC to achieve an
enhanced inrush current limiting function.
Note: Subsequent switch-on cycles at start-up are limited to
max. 10 cycles during the first 20 seconds (cold converter) and
then to max. 1 cycle every 8 s.
will not honor any warranty claims resulting from electric
strength field tests.
Safety of Operator-Accessible Output Circuits
If the output circuit of a converter is operator-accessible, it
shall be an SELV circuit according to IEC/EN 60950.
The table below shows a possible installation configuration,
compliance with which causes the output circuit of a K Series
AC-DC converter to be a SELV circuit according to IEC/EN
60950 up to a configured output voltage of 36 V (sum of
nominal voltages connected in series) .
However, it is the sole responsibility of the installer to
ensure compliance with the applicable safety regulations.
