1 Depending upon the desired output
configuration the wiring should be
made as shown in:
R-Function for
different output configurations.
2 Same conditions for both outputs.
3 If the control voltages are in-
creased above
Uo nom via R-input
control, option P setting, remote
sensing or option T, the output cur-
rents should be reduced accord-
ingly so that
Po nom is not ex-
ceeded.
4 See: Output voltage regulation of
single output units.
5 Condition for specified output.
Other output loaded with constant
current
Io = Io nom. See: Output volt-
age regulation of double output
modules with output 1 and 2 in
symmetrical configuration.
6 See: Typical dynamic load regula-
tion of Uo1 and Uo2.
7 Negative temperature coefficient
(0....–3 mV/cell and K) available on
request.
8 Measured according to IEC/EN
61204 sub clause 3.10 with a
probe acc. to annex A of the same
standards. (See:
Technical Infor-
mation: Measuring and Testing.)
