Output Current Limitation
The G series modules have a current limitation allowing
free choice of load distribution between all outputs, up to a
total current:

In overload all output voltages are simultaneously reduced.
Output Overvoltage Protection
The outputs of the unit are protected against overvoltages
by a second fully independent control loop which disables
the unit. The unit tries to restart after a short time (5 ms).
The main purpose of this second control loop is to protect
against possible overvoltages which could occur due to a
failure in the normal feedback control loop. The second con-
trol loop does not protect the unit against externally applied
overvoltages.
