PAH
1 Input Voltage Range
Input voltage Range for PAH200H48 Series is indicated
below.
Basically, ripple voltage (Vrpl) which results from rectifica-
tion and filtering of commercial AC line is included within
the input voltage as shown in Fig.1-1.
Ripple voltage must be limited within the voltage described
below.
When this value is exceeded, the output ripple voltage be-
comes large.
Note that abrupt input voltage change may cause the out-
put voltage to fluctuate transitionally.
Also, input voltage waveform peak value must not exceed
above input voltage range.
(Standard Model: Negative Logic type for ON/OFF Control)
Input Fuse
PAH200H48 Series module is not internally fused. To en-
sure safe operation and to receive each Safety Standard
approval, please connect an external fuse (fast-blow type)
as shown in Fig.1-2.
Fuse must be connected to the +Vin side if –Vin side is
used as a ground, or fuse must be connected to –Vin side
if +Vin side is used as a ground.
C1: 1μF, C2: 10μF
To reduce spike noise voltage at the output, connect 1μF
ceramic capacitor and 10µF electrolytic capacitor or tan-
talum capacitor between +V and –V within 50mm distance
from the output terminals.
Also, take note that output spike noise voltage could vary
according to PCB wiring design.

Maximum capacitance of electrolytic capacitor that can
be connected between +V and –V, is total 10,000µF.
C3:
Input capacitor C3 is recommended to stabilize to mod-
ule when the module is powered from a high impedance
source.
Select the electrolytic capacitor with low ESR and suffi-
cient allowable ripple current.
Verify actual ripple current value by actual measurement.
Note) 1. Use low impedance electrolytic capacitor with excellent
C4:
When switches or connectors are used between input
source and PAH200H48 Series input terminals, impulse
surge voltage is generated due to input throw-in by switch
on/off or due to inserting/removing of power module from
the active line. For this case, connect an additional elec-
trolytic capacitor C4 as shown in fig.1-3 and fig.1-4.
Also, in-rush current flows at line throw-in.
Therefore, be sure to verify capability of switch or fuse to
withstand I
Reverse input connections
Reverse input polarity would cause module damage.
