1 Over Voltage Protection (OVP)
ZWS5 - ZWS30：
These models are provided by zener-clamp method. If the
output voltage is shutdown by the overvoltage protection
(between 140 - 210 % of output voltage) , the zener diode
must be replaced in order for the output to recover.
ZWS50：
This model is provided with a built-in, handy reset OVP
circuit of output shutdown method. The output will be
down when the output voltage is up to 115 - 135% of the
rated. Once OVP circuit shut the output down, the output
can only be recovered by turning o󱐯 the input line and re-
input the power after interval time . The value of OVP is
xed.
2 Over Current Protection (OCP)
ZWS Series are provided with a built-in primary side OCP
circuit with automatic recovery. OCP is workable when the
load is over 125% of the rated. The power supply will auto-
matically recover when the overload or short conditions are
cleared. Please do not let the unit work under overload or
short conditions over 30 seconds, or the power supply is
feared to be damaged.

3 Ripple
The rated maximum ripple value is the test result measur-
ing by the instructed ripple measuring circuit, using JEITA
probe or other equavalent. If the load cable is too long,
please connect a capacitor (electrolytic, lm, etc) to the
load terminals to reduce the ripple on the load terminal.
4 In-Rush Current
ZWS Series are provided with a built-in inrush current pro-
tecting circuit. ZWS5-ZWS50 are limited by method using
Power Thermistor. The limit current changes depending
on the temperature, it is large at high temperature or while
re-input after period of operation. Be care to select the
switch and the outside fuse.
5 Output Voltage Range
V.ADJ trimmer on PCB can adjust the output volume.
Output voltage range is within ±10 % of nominal output
voltage. To turn the trimmer clockwise, the output voltage
will be increased. Note that over voltage protection (OVP)
function may trigger if the output voltage is increased ex-
cessively.
6 Peak Output Current
Output current can cope with peak current loads. Speci-
ed maximum output current and peak output current must
satisfy formulas below.
Allowable peak output operating duration is less than 10
sec. Cycle should be more than 10ms and duty should be
≦ 0.35.

󱫒 Withstand Voltage Test
ZWS series are designed to be able to withstand 3KVAC
(20mA) 1minute between input-output, 2KVAC (20mA)
1minute between input-FG, and 500VAC (100mA) 1 min-
ute between output-FG.
Please set the limit current value of the withstand voltage
tester as mentioned above before doing test.
Please elevate the applying voltage gradually, and lower it
gradually, too, when shutdown.
Please do not use a timer in the test. Because when the
test voltage is supplied or shut down, an impulse high volt-
age may be generated which will break the power supply
unit.

・All specifications are subject to change without notice.
1 Input Voltage Range
Input voltage range is single phase 85-265VAC （47-63Hz）
or 120-370VDC. Input voltage which is out of specication
may cause unit damage. For cases where conformance to
various safety specs （UL, CSA, EN） are required, input volt-
age range will be 100-240VAC （50/60Hz）.
2 Output Voltage Range
V.ADJ trimmer（VR51）near output connector can adjust the
output voltage within the range. Output voltage range is
within ±10％ of nominal output voltage. To turn the trim-
mer clockwise, the output voltage will be increased. Note
over voltage protection（OVP）function may trigger if the
output voltage is increased excessively.
3 Inrush Current
This series has used Power Thermistor to protect the
circuit from inrush current. Please carefully select input
switch and fuse in cases of the high temperature and re-
input the power.
4 Over Voltage Protection （OVP）
The OVP function （inverter shut down method, manual
reset type）is provided. OVP function operates within
115-135％（5V type: 115-140％）of nominal output volt-
age. When OVP triggers, the output will be shut down. The
input shall be removed for a few minutes, and then re-input
for recovery of the output. OVP setting shall be xed and
not to be adjusted externally.
5 Over Current Protection （OCP）
Constant current limiting, automatic recovery. OCP func-
tion operates when the output current exceeds 125％
（5V type: 105％）of maximum output current of specica-
tion. The output will be automatically recovered when the
overload condition is canceled. Do not operate overload
or dead short conditions for more than 30 seconds, which
could result in damage.
6 Output Ripple & Noise
The standard specification for maximum ripple value is
measured according to measurement circuit specified
by JEITA-RC9131. When load lines are longer, ripple
becomes larger. In this case, electrolytic capacitor, film
capacitor, etc., might be necessary to use across the load
terminal. The output ripple cannot be measured accurately
if the probe ground lead of oscilloscope is too long.

2 Output Voltage Range
V.ADJ trimmer on PCB can adjust the output volume. Out-
put voltage range is within ±10% of nominal output volt-
age. Note that over voltage protection (OVP) function may
trigger if the output voltage is increased excessively.
3 Over Voltage Protection (OVP)
This model is provided with a built-in, handy reset OVP cir-
cuit of output shutdown method. The output will be down
when the output voltage is up to 115 - 135% of the rated.
Once OVP circuit shut the output down, the output can
only be recovered by turning o󱐯 the input line and re-input
the power after interval time.
The value of OVP is xed.
4 Over Current Protection (OCP)
ZWS300 is provided with a built-in primary side OCP cir-
cuit with automatic recovery.
OCP is workable when the load is over 120% of the rated.
The power supply will automatically recover when the
overload or short conditions are cleared.
Please do not let the unit work under overload or short
conditions over 30 seconds, or the power supply is feared
to be damaged.
5 Ripple
The rated maximum ripple value is the test result measur-
ing by the instructed ripple measuring circuit, using JEITA
probe or other equivalent .
If the load cable is too long, please connect a capacitor
(electrolytic lm, etc.) to the load terminals to reduce the
ripple on the load terminal.
