¡For
a receiving inspection, such as Hi-Pot test, increase (de-
crease) the voltage gradually for a start (shut down). Avoid using
Hi-Pot tester with timer because it may generate voltage a few
times higher than the applied voltage, at ON/OFF of a timer.
¡In
the case of use in locations exposed to constant voltage be-
tween primary and secondary is applied, please contact us.
2.4 Remote ON/OFF(MG6, MG10)

2.5 Output Voltage Adjustment Range
¿
-Y2 (Excluding MGW1R5/MGW3/
MGFW1R5/MGFW3/MGXW1R5)
¡The
output voltage is adjustable through an external potentiome-
ter. Adjust only within the range of +10%, -5% of the rated voltage.
¡To
increase the output voltage, turn the potentiometer so that the
resistance value between 2 and 3 becomes small.
¡Please
use a wire as short as possible to connect to the potenti-
ometer and connect it from the pin on the power supply side. Tem-
perature coefficient deteriorates when some types of resistors and
potentiometers are used. Please use the following types.
Resistor
Metal Film Type, Temperature Coefficient of
±100ppm/C or below
Potentiometer Cermet Type, Temperature Coefficient of
±300ppm/C or below
¡In
the case of dual output, ±voltages are adjusted simultaneously.
¡When
the output voltage adjustment is used, note that the output
may be stopped when output voltage is set too high.
3 Wiring to Input/Output

3.1 Wiring Input Pin
(1) External fuse
¡Fuse
is not built-in on input side. In order to protect the unit, install
the normal-blow type fuse on input side.
¡When
the input voltage from a front end unit is supplied to multiple
units, install the normal-blow type fuse in each unit.

(2) External capacitor on the input side
¡Basically,
MG series does not need any external capacitor.
Adding a capacitor Ci near the input pin terminal and reduce re-
flected input noise from a converter.
Please connect the capacitor as needed.
¡When
you use a capacitor Ci, please use the one with high fre-
quency and good temperature characteristics.
¡If
the power supply is to be turned ON/OFF directly with a switch,
inductance from the input line will induce a surge voltage several
times that of the input voltage and it may damage the power sup-
ply. Make sure that the surge is absorbed, for example, by con-
necting an electrolytic capacitor between the input pins.
¡If
an external filter containing L (inductance) is added to the input
line, or a wire from the input source to the DC-DC converter is
long, not only the reflected input noise becomes large, but also
the output of the converter may become unstable. In such case,
connecting Ci to the input pin terminal is recommended.
¡If
you use an aluminum electrolytic capacitor, please pay attention
to its ripple current rating.
