Output Waveform
This unit’s output waveform
is referred to as ”square
wave“ of ”modified sine
wave“. It is a stepped
waveform designed to have
characteristics similar to the
sine wave shape of utility
power. A waveform of this
nature is suitable for most
AC loads (including linear
and switching power suppliers
used in electronic equipment,
transformers and motors).
