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.

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.
