1 INTORDUCTION
PH300S, 600S series are applicable to operate in parallel
with an external circuit using CS signal terminal.
There are 2 different kinds of parallel operation.
It is possible to enhance the output when load current can
not be supplied by only one power module or to improve
the reliability by derating the output power of each module.
For power supply that is required high reliability, it is pos-
sible to achieve the requirement by using N+1 units of
power modules for the load of N units.
In N+1 units of parallel operation, even through one of the
power modules is failed the performance of the system
shall be maintained because the other units cover the fail-
ure module and share the load currents.
2 PRECUATIONS
There are several basic cautions and warnings in parallel
operation of PH300S, 600S series.
● Externally attach a control circuit of parallel operation
● Available to use 11 units maximum of power modules in
● Use specified components followed by explanations of
● Set the accuracy of the output voltage within ±1% to
● Set the maximum load current below 95% of sum of the
● Use same length and size of output load lines between
