0.5%±10W
※
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 300kHz.
※
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.
