C5: 0.1μF
To reduce spike noise voltage at the output, connect a ce-
ramic 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.
C6:
When switches or connectors are used between input
source and PAH300, 350S48 Series input terminals, im-
pulse 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
electrolytic capacitor C6 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
line throw-in.
Reverse input connection
Reverse input polarity would cause module damage. For
cases where reverse connections are possible, connect a
protective diode and fuse. Use protective diode with higher
voltage rating than the input voltage, and with higher surge
current rating than the fuse.

2 Output Voltage Adjustment Range
Output voltage could be adjusted within the range de-
scribed below by external resister or variable resistor.
However, take note that OVP might trigger when output
voltage adjustment exceeds the ranges indicated below.
When increasing the output voltage, reduce the output
current accordingly so as not to exceed the maximum out-
put power.
Take note that input voltage range is limited as shown in
fig.2-1 when output voltage is increased.
Remote sensing is possible even when output voltage is
varied. For details on remote sensing function, please refer
to “9. Remote Sensing” .

with the above recommended filter at Densei-Lambda
measuring conditions. However, there are cases
where above limits might not be satisfied due to in-
put and output wiring method, as well as, peripheral
circuits. When selecting input filter, be sure to verify
actual EMI characteristics (CE and RE) before finaliz-
ing the filter. Refer to PAH300, 350S48-＊ Evaluation
Data for details.
