DESCRIPTION
The NMV Series offers single or dual output
versions in the same size package as the
popular NMA series. The higher isolation is
particularly useful in control type applications
where the standard 1kV is not sufficient.

i When operated
without
additional external load capacitance, the output voltage of the devices is guaranteed
to be within 95% of its steady state value within 100ms after the input voltage has reached 95% of its steady
state value,
irrespective of the rise time of the input voltage.
ii When operated
with
additional external load capacitance the rise time of the input voltage will determine the
maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the
greater the maximum value of the additional external capacitance for reliable start up.
