 ON/OFF Control (CNT Terminal)
Without turning the input on and off, the output can be en-
abled and disabled by CNT function. The control circuit is
at input (primary) side, and CNT terminal pin is used. Use
-Vin terminal as ground of CNT terminal.
If this function is unnecessary, shorten between CNT ter-
minal and -Vin terminal.
1） Maximum applied voltage to CNT terminal is 35V, and
2） CNT terminal can be managed by opening and closing
－ Caution －
Inside of power module could be damaged at applying in-
put without or improper contact of -V connection. For an
example, the current flows in abnormal path such as +Vin
to CNT terminal leads CNT terminal blow out
To avoid such a damage, ensure all the terminals are con-
nected before input is applied.
 CS Signal (CS)
Negative voltage based on -Vo is generated for CS termi-
nal. Using this signal, it is possible to operate in parallel by
attaching parallel operating control circuit externally.
Refer to “Parallel Operation” Application Note in the in-
struction manual for details.

the maximum reversed voltage is -0.7V. Also, the cur-

 Series Operation
Series operation is available for all models of PH300S,
600S series.
Contact us for details of the maximum unit number of pos-
sible connections.
 I.O.G. Signal (IOG Terminal)
Using IOG (Inverter Output Good Signal) terminal, it is pos-
sible to monitoring good/not good operation in the power
module. This monitoring signal is located at secondary
(output) side and is the open collector output.
At normal inverter operation, the IOG shows LOW (maximum
sink current 5mA and maximum applied voltage 35V).
Ground of IOG terminal is -S terminal.
Be aware IOG signal could be unstable in the following
cases.
● Active OCP
● Low load in parallel operation
● Sudden change of load
Contact us for the details.
 Operating Temperature
Installation direction is freely chosen, but consider air con-
vection not to shut heat up in power module. Decide instal-
lation direction of printed circuit board and dispositions of
components for better air convection in both forced air or
convection cooling.
To keep the baselate temperature below 100 ℃ in actual
