1） The maximum applied voltage to CNT terminal is 35V,
2） ON/OFF control can be controlled by the device
― Caution ―
If –Vin is not connected, or improperly connected, internal
circuit of power module could be damaged when input is
applied. For example, CNT terminal could blow out when
current flows through an abnormal path such as +V
CNT created by improper connection.
To avoid such a damage, ensure all the terminals are
connected before input is applied.
 PARALLEL OPERATION (PC TERMINAL)
Only F type power modules provide PC terminal. By con-
necting PC terminal of each module, up to 11 units of
same model (same output voltage and current) can be con-
nected in parallel, and the output current is equally shared
among each power module.
Note that maximum output power of each module should
not exceed specifications.
By setting accuracy of output voltage of each power mod-
ule in parallel operation within ±1%, the maximum load
current can be used up to 95% of nominal output current
value.
2 units of PH300F48-5 are to be used in parallel operation.
The total nominal output current is 120A,
then
120×0.95＝114 （ A）
will be calculated as the maximum load current.
For details of parallel connection and redundant operation,
refer to Application Note “Parallel Operation.”

and the reversed voltage is -0.7V maximum. Source
current of CNT terminal is approximately 0.5mA. If the
wire would be long, attach 0.1 μ F capacitor between
CNT terminal and SG terminal.

insulated by relay or photocoupler.
＊When using photocoupler, connect CNT and SG ter-

 SERIES OPERATION
Series operation is available for all PH series models.
Contact us for maximum allowable units that can be used
in series operation.
In series operation for high output voltage configurations,
attach a by-pass diode to avoid to applying reverse volt-
age.

(Schottky barrier type)
No diode is necessary if + side load and - side load are
completely separated.
 I.O.G. SIGNAL (IOG TERMINAL)
I.O.G. signal is provided in the F type power module. By
using IOG terminal, good/no good operation can be moni-
tored.
This monitoring signal output is in the secondary (output)
side and is an open collector output.
At good inverter operation, IOG monitors LOW (maximum
sink current = 5mA; maximum applied voltage = 35V).
