1 Efficiency at Ui nom and Io nom.
2 If the output voltages are increased above Uo nom via R-input control, option P setting, remote sensing or option T, the output currents
should be reduced accordingly so that
Po nom is not exceeded.
3 Series connection of output 1 and 2.
4 Second output semi-regulated.
5 Option V for LS 1001 types only.
If the output circuit of an AC-DC converter is operator-ac-
cessible according to the IEC 950 related safety standards,
it shall be an SELV circuit (Safety Extra Low Voltage circuit,
i.e. a circuit, separated from mains by at least basic insula-
tion, that is so designed and protected that under normal
and single fault conditions, the voltage between any two
conductors and between any conductor and earth does not
exceed 60 V DC).
In the following section an interpretation is provided of the
IEC 950 safety standard with respect to the safety status of
the output circuit. However, it is the sole responsibility of the
installer or user to assure the compliance with the relevant
and applicable safety standards:
Safety and Installation Instructions
Safety:
For safety reasons, the power supplies should be wired
via the female connector H15 (according to DIN 41612,
see "Accessories") in order to meet national and interna-
tional safety requirements
If the AC-DC converter is installed acoording to the relevant
safety regulations, its output is considered to be an SELV
circuit up to a nominal output voltage of 36 V.
The converters correspond to safety class I equipment and
comply with IEC 950, EN 60950, VDE 0805 Part 100 (in-
cluding manufacturing surveillance), UL 1950, CSA/C22.2
No. 950-95 and are VDE approved.
The connector has a leading earth connection pin which
ensures earth connection prior to any other.
The UL 1950 recognition limits the ambient operational
temperature range of the standard modules (-7) to
–25...50
°C. In applications where the full operational tem-
perature range of –25...71
°C under UL condition is re-
quired, forced cooling should be provided. The European
approval boards have in contrast accepted the converters
to be operated up to
T A max without any further precautions.
