Caution
A.
Do not connect multiple power supplies in series as it may cause damage
or malfunction.
B.
While in parallel connection mode, the output voltage of each power
supplies should be set to equal values. If the setting value of each unit is
not the same, the higher output voltage will feed back to the smaller unit
and damage its internal components.
C.
When the AC input voltage is lower than the full-load voltage which is
100 VAC, the supplies will activate an inner overtemperature protector
and cut off the output in response to the condition. To ensure that the
entire test process can be completed smoothly, confirm that the input AC
