Test Sockets (Main output only )
Test sockets for measuring the output voltage
Uo1 are lo-
cated at the front of the module. The positive test socket is
protected by a series resistor (see:
Functional Description,
block diagrams). The voltage measured at the test sockets
is approximately 30 mV lower than the value measured at
the output terminals.
In case of double output units externally connected in se-
ries for
Uo = 24 V, 30 V or 48 V the monitored output volt-
age is 12 V, 15 V or 24 V respectively.
