SWS
Input voltage range is single phase 85 - 265VAC (47 - 63Hz) or
120 - 350VDC. Input voltage, which is out of specifi cation, may
cause unit damage. Rated input voltage for safety standard
application is 100AC-240VAC (50/60Hz).
Output voltage is set to the rated value at shipment. V.ADJ trim-
mer on the front panel side can be used to adjust the output
voltage within the range specifi ed (refer to specifi cations for
adjustable range).
To turn the trimmer clockwise, the output voltage will be in-
creased. Take note when the output voltage is increased ex-
cessively, over voltage protection (OVP) function may trigger
and output voltage will be shut down.
The OVP function (inverter shutdown method, manual re-
set type) is provided. OVP function operates within
range (refer to specifi cation)
and the output will be shut down when OVP function triggers
(refer to specifi cations for OVP range of each models). To reset
OVP, remove the input of power supply for a few minutes, and
then re-input. Or, use CNT to reset (remote ON/OFF : OFF to
ON). OVP value is fi xed and not to be adjusted externally. Never
apply more than rated output voltage to output terminal, which
may lead to damage. In the case of inductive load, use decou-
pling diode at output line.
The OCP function is provided. OCP characteristic is constant
current limiting, automatic recovery. OCP function operates
when the output current exceeds 105% (24V output model:
101% of peak current) of maximum DC output current speci-
fi cation. The output will be automatically recovered when the
overload condition is cancelled. Never operate the unit under
over current or shorted conditions for more than 30 seconds,
which may lead to damage. OCP setting is fi xed and not to be
adjusted externally.
The OTP function (manual reset type) is provided. When ambi-
ent or internal temperature rises abnormally, OTP function op-
erates and output will be shut down. After shut down, remove
the input and cool it down to reset OTP. Then re-input.
Power failure detection circuit is provided. ALM (Alarm) signal
will turn“High”level to indicate the abnormal status when con-
verter stops. Please take note in parallel or N+1 operation at light
load condition, maybe only one of the power supply operates
and other power supply stops. When the built-in FAN motor of
this power supply unit stops, ALM signal will turn to “High” too.
If the output voltage is decreased to less than 20% of rated
voltage, or decreased rapidly through an external adjustment
mechanism when load is light, the ALM signal may turn “High”.
The ALM signal is isolated from input and output by a photo-
mosfet. It uses the open collector method shown as below.

4. Functions and Precautions
specifi ed
This function compensates voltage drop of wiring from output
terminals to load terminals. Connect “+S” terminal to “+” termi-
nal of load and “-S” terminal to “-” terminal of load with sensing
wires. The total line voltage drop (+ side line and - side line) shall
be less than 0.3V. In case that sensing lines are too long, it is
necessary to put an electrolytic capacitor in following places.
When the function of remote sensing is not used, connect +S
terminal to +Vm terminal, and -S terminal to -Vm terminal by the
attachment connector.
If remote sensing terminals are opened, the stability and the
accuracy of the output deteriorated. Therefore, terminal +S, -S
must be connected.
Remote ON/OFF control is provided.
Using this function, output on/off is allowed to control without
input voltage on/off.
Specifications of remote ON/OFF
CNT2-TOG current or voltage condition:
(1) The maximum input voltage to CNT2 terminal is 12V, and the
(2) A switch and relay or a transistor can be used as ON/OFF switch.
(3) Remote ON/OFF control circuit is isolated from the input
(1) across the load terminal,
(2) between “+S” terminal and “+V” terminal,
(3) between “-S” terminal and “-V” terminal.
