Signals
HPU1K5
AC OK/Power Fail
AC OK is an isolated signal providing a minimum of 3 ms warning of loss of
output regulation. The signal is fully isolated and the collector and emitter must
be connected externally.
Maximum sink current 2 mA, maximum voltage 20 V.
DC OK
DC OK is an isolated signal providing warning that the output voltage has fallen
below 90% of nominal. The signal is fully isolated and the collector and emitter
must be connected externally.
Maximum sink current 2 mA, maximum voltage 20 V.

Current Share
Connecting pins 5 or 6 and 3 or 4 of like voltage units (8 maximum) will force the
current to share between the outputs. Units share current within 10% of each
other at full load. Derate output to 90% of total combined load.
