Series Connection For Increased Output Voltage; Series Connection For Positive And Negative Output Voltage - TDK-Lambda GH10-100 User Manual

Wenn Stromversorgungen in Reihe geschaltet sind und die Ausgangsklemmen potentialfrei sind
(einschließlich den Lastklemmen),
folgenden Definition aufweisen:
Bei den Ausgangsmodellen von 10 ~ 100VDC: An den Anschlüssen darf kein größeres Potential
von bis zu +/- 200VDC gegen Erde haben.
Bei den Ausgangsmodellen 150 ~ 600VDC: An den Anschlüssen darf kein größeres Potential von
bis zu +/- 600VDC gegen Erde haben.
d.h. 600VDC Ausgangsspannungen können in Reihe geschaltet werden, um 1200VDC zu erzeugen,
solange die maximale Spannung an jeder Ausgangsklemme (plus oder minus) +/- 600VDC gegen Erde
nicht überschreitet.

Series Connection for Increased Output Voltage

Two units are connected so that their outputs are summed. Set the current limit of each power
supply to the maximum that the load can handle without damage. It is recommended that diodes be
connected in parallel with each unit output to prevent reverse voltage during start up sequence or
in case one of the units shuts down. Each diode should be rated to at least the power supply rated
output voltage and output current. Refer to Figure 2–5 for series operation with local and remote
sensing.

Series Connection for Positive and Negative Output Voltage

In this mode, two units are configured as positive and negative output.
Set the current limit of each power supply to the maximum that the load can handle without
damage. It is recommended that diodes be connected in parallel with each unit output to prevent
reverse voltage during start-up or in case one of the units shuts down. Each diode should be rated
to at least the power supply rated output voltage and output current. Refer to Figure 2–6 for this
operating mode.
