PH
When OCP is operating, IOG signal becomes unstable.
Ground of IOG terminal is -S terminal.
In parallel operation as shown as Figure13-1, the minimum
load current shall be more than 10% of the total nominal
output current. Note that If load is less than 10%, IOG sig-
nal may be unstable.
In a parallel application where diode is used at the output
of the power module, required minimum load current is not
specified.
(Sensing point is at anode side of the diode.)
2 units of PH300F48-5 are to be used in parallel opera-
tion. The total nominal output current is 120A,
then
120×0.1＝12（A）
will be calculated as the minimum load current.
 AUXILIARY POWER SUPPLY FOR
AUX terminal is provided inside the F type power module.
The output voltage of AUX terminal is in the range of 7 - 10
VDC, and the maximum output current is 10mA.
When using this terminal in parallel connection with other
AUX terminal in DC/DC power modules, a diode must be
attached. See Fig13-1 for connection example. Even for
this case, maximum output current should be 10mA.
Avoid connecting AUX terminal directly with other termi-
nals of the module because this may damage the power
module.
Ground of AUX terminal is -S terminal.
 OPERATING TEMPERATURE
By maintaining baseplate temperature below 85℃ at actual
operating conditions, operation is possible. For details of
thermal design, refer to Application Note “Thermal Design.”
 OPERATING HUMIDITY
Note that dew condensations may cause abnormal opera-

tion and damage to power module.
 STORAGE TEMPERATURE
Note that abrupt temperature changes may cause conden-
sation and bad effects on soldering.
 STORAGE HUMIDITY
Storing power modules in high temperature and high hu-
midity creates oxidation on each terminals and causes sol-
dering problems.
 COOLING METHOD
Because the operating temperature range is prescribed by
baseplate temperature, several cooling methods are pos-
sible.
For details of thermal design, refer to Application Note
 BASEPLATE TEMPERATURE VS.
Baseplate temperature vs. output regulation is defined as
the output voltage deviation ratio when operating baseplate
temperature is changed.
 WITHSTAND VOLTAGE
This PH series is designed to withstand 2.5kVAC between
input and baspelate, and 3kVAC between input and output
for 1 minute each. (For 24VDC input model, it is designed
to withstand 2kVAC between input and baseplate, and
2kVAC between input and output for 1 minute). When
withstand voltage test would be carried out at incoming
inspection etc., the limit value of the tester shall be set at
20mA.
