V ACFAIL Signal (VME)
Available only for models with V
This option defines an undervoltage monitoring circuit for
the input and main output voltage. It generates the ACFAIL
signal (V signal) according to the VME standard.

The low state level of the ACFAIL signal is specified at a
sink current of I
output of an NPN transistor). The pull-up resistor feeding
the open-collector output should be placed on the VME
backplane.
