Some of the withstand voltage tester may generate
high voltage at the matching with monolithic ceramic
capacitor and may cause the unit damage.
So, please check the waveform of test voltage.
Output Peak power
This product must be use to satisfy (a) and (b).
Allowable peak output operating time is less than 5sec.
When the product operate peak power for more than 5 sec,
the delay shut down function operates and the output will
shut down.
Peak output power and average output power use less
than specifi cation.
Peak output power is limited depending on Duty. The
details see at (b).
The product might be damage to use beyond the limits of
(a) and (b).
When using pulse load, a noise may be heard from power
supply unit. Please evaluate and check before using.
(a) Expression of relations
A formula about Duty
A formula about average output power
Wp ： Peak output power ( W )
Wav ： Rated average output power( W )
( Average output power of Specifi cation )
Wm ： Average output power ( W )
τ
： Pulse width of peak output power ( sec )
( Operating time at peak output )
T ： Period ( sec )
(b) Peak output power VS Peak Duty
