6-1. Input voltage
Input voltage range is single-phase 85 - 265VAC (47 - 63Hz).
The maximum power is different for the input voltage range 85 - 132VAC (47 - 63Hz) and 170 –
265VAC (47 - 63Hz), and the protection function threshold switches depending on the input voltage.
When switching the input voltage from the 100V line to the 200V line, or from the 200V line to the
100V line, first cut off the input and wait 60 seconds before switching.
Applying input voltage outside of specifications may damage the power supply.
The safety standard certified input voltage range is 100 - 120VAC/200 - 240VAC (50 - 60Hz).
6-2. Input inrush current
The switch method is used for limiting the inrush current. Higher current might flow when input turn
on interval is short.
First inrush current and second inrush current flow. Select input switch and external fuse carefully.
6-3. Variable output voltage (variable constant voltage output setting value)
In the initial state, the output voltage of the power supply is set to the nominal output voltage value.
The output voltage can be set using the built-in output voltage adjustment trimmer or external signals
(communication function, CV terminal external voltage application, CV terminal external current
application).
When using the product at a voltage exceeding the rated voltage, it is necessary to derate the output
current so as not to exceed the maximum output power.
6-3-1. Variable with built-in output voltage adjustment trimmer
The built-in output voltage adjustment trimmer allows you to change the constant voltage output value
setting.
Turning the output voltage adjustment trimmer clockwise, the output voltage will be increased.
For the output voltage variable range refer to specifications (A291-01-01_).
