●Basic Connection
Input Fuse
No internal fuse is provided in power module. To ensure
safety operation and to acquire safety standard approvals,
attach an external fuse. The external fuse must be fast
blow type and shall be attached to each power module in-
dividually.
Furthermore, attach the fuse at +V
minal is at -V
at +V
When the in-rush current causes some trouble at low im-
pedance, use in-rush limiting circuit if necessary.
C1 ：C1a/C1b
Attach capacitor(s) either between +V
terminal or before L1.
As shown in Table1-3, location of the capacitor will be ei-
ther C1a or C1b depending on each input voltage.

Because the ripple current flows in the capacitor, confirm
the allowance of the ripple current prior to selection of the
component.
In addition, attaching a film capacitor C1b (severalμF)
which can withstand large ripple currents is very effective
in reducing the ripple current for 110V and 280V input
models.
The following low ESR type Nippon Chemi-con capacitors,
or equivalent are recommended:
For 24V input, use LXY Series
For 48V input, use LXV Series
For 110V and 280V input, use KMG Series
L1 ：
To reduce ripple current at C1 and output spike noise, at-
tach common mode choke coil(s) in each power module
individually.
Note: Depending on input filter construction, noise level might
To avoid mis-operation and spike noise problem, use an in-
ductance which has a few tens μH of normal component.
C2 ：4700pF
To improve the noise characteristics, use a ceramic capac-
itor which has high withstand voltage when safety standard
is necessary to acquire.
24VDC Input: more than 2kVAC
48VDC Input: more than 3kVAC
110VDC Input: more than 3kVAC
280VDC Input: more than 3kVAC
During withstand voltage test, test voltage is applied
across this capacitor. Therefore, select components with
above recommended withstand voltage.
C2 shall be connected in between -Vin and baseplate as
short as possible.
C3 ：
To avoid the effects of the output line impedance to the
power module, attach a capacitor between +V terminal
and -V terminal. Equivalent series resistance and equiva-
lent series impedance of the electrolytic capacitor wiring
may have some influence at the output during shutdown,
or at the output ripple. The output ripple voltage may vary
depending on the wiring method of printed circuit board.
See the table shown at the end of this section. (Reference
table for C3 Value.)
C4 ：
In case switch and connectors are used between the
input power source and input terminals of the PH series,
transient surge voltage may occur when switch is turned
on/off, or during hot swap at active input line. Therefore,
attach a capacitor C4 as shown in Figure1-4.
Recommended Impedance Values:
exceed noise specification and mis-operation might occur
due to resonance of the filter.
