Output Voltage Regulation of Double Output Modules
Output 1 is under normal conditions regulated to
Uo1 nom,
independent of the output currents.
Uo2 is dependent upon the load distribution. If both outputs
are loaded with more than 10% of
Io nom, the deviation of Uo2
remains within
±5% of the value of U
o1. The following 3
gures 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 U
o1 pro-
vided that a total load of more than 10% of
Io nom is applied.
Two outputs of a single K 5000 module connected in paral-
lel will behave like the output of a K 4000 module; the paral-
leled output is fully regulated. No precautions are neces-
sary in using the R-input and the test sockets.
