JFET
V ACFAIL Signal (VME)
Available for converters with V
undervoltage monitoring circuit for the input or the input and
main output voltage equivalent to option D and generates the
ACFAIL signal (V signal), which conforms to the VME
standard. The low state level of the ACFAIL signal is specified
at a sink current of I
