Rated operational power
Mode of Operation
Connected to the 3 phases
(and neutral) DPB71 oper-
ates when all 3 phases are
present at the same time, the
phase sequence is correct
and the phase-phase (or
phase-neutral) voltage levels
are within set limits.
If one or more phase-phase
or
exceeds the upper set level
or drops below the lower set
level, the red LED starts
flashing 2 Hz and the output
relay releases after the set
time period. If the phase
sequence is wrong or one
phase is lost, the output
relay releases immediately.
Only 200 ms delay occurs.
The failure is indicated by the
red LED flashing 5 Hz during
the alarm condition.

Example 1
(mains network monitoring)
The relay monitors over and
under voltage, phase loss
and correct phase sequence.
Example 2
(load monitoring)
The relay releases in case of
interruption of one or more
phases, when one or more
voltages drop below the low-
er set level or exceed the
upper set level.
