Output Voltage Regulation of Single or Double Output
Modules with Outputs 1 and 2 Connected in Series
Output Voltage Regulation of Double Output Modules
with Output 1 and 2 in Symmetrical Configuration
Output 1 is under normal conditions regulated to
Uo1 nom,
independent of the output currents.
Uo2 is dependent upon the load distribution. When both out-
puts are loaded with more than 10% of
Io nom, the deviation
of
Uo2 remains within ±5 % of the value of Uo1. The following
3 figures show the regulation with varying load distribution.
If
Io1 = Io2 or the two outputs are connected in series, the de-
viation of
Uo2 remains within
±1% of the value of Uo1 pro-
vided that a total load of more than 10 % of
Io nom is applied.
Two outputs of a single S 2000 module connected in paral-
lel will behave like the output of a S 1000 module; the paral-
leled output is fully regulated. No precautions are neces-
sary in using the R-input and the test sockets.
