Ac Fail Alarm; Series Operation - TDK-Lambda GH10-100 User Manual

2.9.7

AC Fail Alarm

The AC Fail alarm indicates whether the AC input has been shut down or AC input is incorrect.
When any of these faults occur, the display shows AC FAULT, Output power is disabled, and the
alarm RED LED blinks 1/2 Hz frequency.
Safe start mode: The power supply stays off after AC power returns. The display shows OUT OFF.
Auto-restart mode: The power supply recovers to its last setting automatically when the AC power
returns.

Series Operation

Power supplies of the same model (up to two units) can be connected in series to obtain increased
output voltage.
When power supplies are connected in series, and the load or one of the output terminals is
grounded, no point may be at a greater potential according to the following definition:
For 10 ~ 100VDC rated output: No point may be at a greater potential of +/- 200VDC from ground.
For 150 ~ 600VDC rated output: No point may be at a greater potential of +/- 600VDC from
ground.
Wenn Stromversorgungen in Reihe geschaltet werden und die Last oder eine der
Ausgangsklemmen geerdet ist, darf kein Anschluss ein größeres Spannungspotential gemäß der
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.
When power supplies are connected in series, and the output terminals are floating (including
load terminals), no point may be at a greater potential according to the following definition:
For 10 ~ 100VDC rated output: No point may be at a greater potential of +/- 200VDC from ground.
For 150 ~ 600VDC rated output: No point may be at a greater potential of +/- 600VDC from
ground.
i.e. 600VDC output power supplies can be connected in series, as long as the maximum voltage
on any output terminal (plus or minus) does not exceed +/- 600VDC to ground.
