Instruction Manual
■Before
using this product
Be sure to take note of precautions and warnings indicated in this manual when using this product. Improper usage may
lead to electric shock or fire. Be sure to read this instruction manual thoroughly before using this product
■Precautions
●
Avoid touching the baseplate and the case of this product because they get hot.
●
There are high voltage and high temperature components within this product. Refrain from disassembling this product
or touching its internal components as this may lead to electric shock or burn.
●
To avoid unexpected accid from placing hands or face near the unit during operation.
●
Verify that connection to input, output ents, refrain and signal terminals are correct as indicated in this instruction
manual.
●
For acquisition of various Safety Standards and safety improvement, be sure to use an external fuse. This product is
designed for installation on electronic equipment.
●
For input terminals of 48 V input models, apply a voltage from a primary source with reinforced or double insulation.
●
Output voltage of this product is considered to have hazardous energy level (voltage of 2V and above with power of
240W and above) and must not have physical contact with operator. Protection must be provided on this module
when installed on equipment to prevent physical contact with service technician himself or accidentally dropped tools
during repair. Before repair, be sure to turn off the input source and confirm that input and output voltage have drop
down to a safe level.
●
Application circuit or component values described in this instruction manual are for reference only. When designing
circuit, be sure to verify actual circuit operation before determining final application circuit or component values.
Contents of this instruction manual are subject to change without notice. When using this product, please refer to latest

Explanations on Specifications:
1. Input Voltage Range
Input voltage range for PAF500½600½700F48 Series
is indicated below.
Input Voltage Range : 36½76VDC
Basically，ripple voltage (Vrpl) which results from
rectification 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.
Allowable input ripple voltage : 4Vp-p
When this value is exceeded, the output ripple
voltage becomes large.
Note that sudden input voltage change may cause
variation of output voltage transitionally.
Also, input voltage waveform peak value must not
exceed above input voltage range.
Input Fuse
This power module has no built-in fuse. Use external
fuse to acquire various Safety Standards and to improve
safety. Also, use fast-blow type for every module.
Furthermore, fuse must be connected to the +Vin
side if –Vin side is used as ground, or fuse must be
connected to –Vin side if +Vin side is used as a ground.
Input Fuse recommended current rating: 30A
(F30AH, 100/250V)
C1 :
To prevent the effect of input line inductance to the
power module, connect electrolytic capacitor or
ceramic capacitor between +Vin and –Vin terminals.
Furthermore, use electrolytic capacitor with small
ESR value. Especially take note that during line turn
off at low ambient temperature, power module output
will not normally shut down due to unstable C1 voltage.
Also, ripple current flows across this capacitor.
Therefore, verify maximum allowable ripple current
this capacitor when selecting component. Verify actual
ripple current value by actual measurement.
Recommended capacitor value
PAF500½600F48: 100μF and above
(voltage rating 100V and above)
PAF700F48: 220μF×2 and above
(voltage rating 100V and above)
Note)
1. Use low impedance electrolytic capacitor
with excellent temperature characteristics.
(Nippon Chemicon LXV Series or equivalent)
2. When input line inductance becomes
excessively high due to insertion of choke
coil, operation of the power module could
become unstable. For this case, increase
C1 value more than the value indicated
above.
3. For PAF500½600F48 series, when ambient
temperature becomes lower than –20℃,
connect two capacitors indicate above in
parallel to reduce ESR.
C2 : 10μF
To reduce spike noise voltage at the output, connect
a ceramic 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.
