“n the fr“nt
surface “f the ”r“duct fr“m –10% t“ +15% “f the rated “ut”ut v“ltage.
Turning cl“ckwise increases the “ut”ut v“ltage, and turning c“untercl“ckwise
decreases the “ut”ut v“ltage.
N“tes:
1. If the “ut”ut v“ltage is adjusted t“ less than 20V (fact“ry setting), the
underv“ltage alarm functi“n may be activated.
2. D“ n“t exceed the rated “ut”ut ca”acity and current after adjusting the “ut”ut

t“gether > f“r 1 minute.
When testing, set the cut“ff current f“r the withstand v“ltage test device t“ 20mA.
N“tes:
1.Sudden switching “f 3000VAC may ”“ssibly cause a v“ltage surge, damaging
the ”“wer su””ly. Increase/decrease test v“ltage gradually.
2.Be sure t“ sh“rt-circuit all the “ut”ut terminals and the Alarm “ut”ut terminals “f
the ”“wer su””ly t“ ”r“tect the ”“wer su””ly fr“m damage.
■
Insulati“n Resistance Test
When testing the insulati“n resistance “f the ”“wer su””ly, use a DC “hmmeter at
500VDC.
N“te:
Be sure t“ sh“rt-circuit all the “ut”ut terminals
and the Alarm output terminals
“f the
”“wer su””ly t“ ”r“tect the ”“wer su””ly fr“m damage.
■
Overl“ad Pr“tecti“n
The l“ad and the ”“wer su””ly are aut“matically ”r“tected fr“m “vercurrent damage
by this functi“n.
Overl“ad ”r“tecti“n is activated if the “ut”ut current rises ab“ve 105% “f the rated
current.
When the “ut”ut current returns within the rated range, “verl“ad ”r“tecti“n is
aut“matically cleared.
N“tes:
1.If the ”“wer su””ly has been sh“rt-circuited “r su””lied with an “vercurrent l“nger
than 20 sec“nds, the internal ”arts “f the ”“wer su””ly may “ccasi“nally be
deteri“rated “r damaged.
2.The internal ”arts may ”“ssibly be deteri“rated “r damaged. D“ n“t use the
”r“duct f“r a””licati“ns where the l“ad causes frequent inrush current and
“verl“ad.
■
Overv“ltage Pr“tecti“n
This ”“wer su””ly aut“matically ”r“tects itself and the l“ad fr“m “verv“ltage.
Overv“ltage ”r“tecti“n is activated if the “ut”ut v“ltage rises ab“ve a””r“x. 130% “f
the rated “ut”ut v“ltage.
T“ reset the ”“wer su””ly, leave the ”“wer su””ly “ff f“r m“re than 3 minutes and
then turn it “n again.
N“te:
Be sure t“ clear the cause “f the “verv“ltage, bef“re turning “n the ”“wer su””ly.

In Case there is N“ Out”ut V“ltage
The ”“ssible cause f“r n“ “ut”ut v“ltage may be the ”resence “f an “verl“ad “r
“verv“ltage c“nditi“n, “r may be due t“ the functi“ning “f an latching ”r“tective
device. The latching ”r“tecti“n may “”erate if a large am“unt “f surge v“ltage such
as a lightening surge “ccurs while turning “n the ”“wer su””ly.
In case there is n“ “ut”ut v“ltage, ”lease check the f“ll“wing ”“ints bef“re
c“ntacting us:
Check the Overl“ad Pr“tected Status:
• Check whether the l“ad is in “verl“ad status “r is sh“rt-circuited. Rem“ve wires t“
l“ad when checking.
• Attem”t t“ clear the “verv“ltage “r latching ”r“tecti“n functi“n:
Turn the ”“wer su””ly “ff “nce, and leave it “ff f“r at least 3 minutes. Then turn it
“n again t“ see if this clears the c“nditi“n.
