NOTES
※
5
：
Fluctuation when the source voltage is changed by ±10% in the range from
AC100V to 240V.
※
6
：
Fluctuation when
the load is changed from the rated load into no load (open
circuit) at the rated output voltage.
※
7
：
Measured at the frequency up to 20 MHz.
※
8
：
Measured at the frequency up to 1 MHz.
※
9
：
Response time till the output voltage is restored to the range within 0.1% +
10 mV of the rated output voltage when the output current is changed from
50% to 100% of the maximum output current at the rated output voltage.
※
10
：
Value with a fixed load.
Time until the output voltage increases up to 10% to 90% of the rated output
voltage.
※
11
：
Value with a fixed load.
Time until the output voltage decreases down to 90% to 10% of the rated
output voltage.
※
12
：
Value after 30 minutes of warming up (excluding external control).
※
13
：
Fluctuation when the load is changed from the rated load into no load (short
circuit) at the rated output current.
