1 Input Voltage Range
Input voltage ranges for PH300S, 600S series are as fol-
low.
Input voltage normally includes ripple voltage (Vrpl) as
shown as Figure1-1. The ripple voltage shall be less than
following values.
Peak of input voltage wave shall not be exceed above in-
put voltage range.
Output voltage would be fluctuated as dynamic line chang-
es.
The output ripple voltage may become bigger if the bottom
of input ripple voltage is below 220V for 280VDC input
model and below 40VDC for 48VDC input model.

Input Fuse
No internal fuse is provided in the power module. To en-
sure the safety operation and to acquire safety standard
approvals, attach an external fuse. The external fuse must
be fast blow type and be attached to each module indi-
vidually.
Furthermore, attach the fuse at +Vin side if the ground is
-Vin side and at -Vin side if the ground is at +Vin side.
Use in-rush current limit circuit when the in-rush current
may make troubles.
C1:
Attach electrolytic capacitor(s) between +Vin and -Vin ter-
minals.
The capacitor shall be lower equivalence series resistance
(ESR). Especially under low ambient temperature, the
voltage of C1 becomes unstable due to ESR at line off.
Hence, be aware the output might be not normal line off.
Confirm the allowance of ripple current because ripple cur-
rent flows in the capacitor, and then choose the capacitor.
Recommended Capacitor Values
L1:
To reduce C1 ripple current and output spike noise volt-
age, attach a normal choke coil to each module.
