Product Description
DWB02 and PWB02 are
precise TRMS active power
monitoring relays for 3-
phase balanced systems.
They can be used for moni-
toring the actual load of
asynchronous motors and
other symmetrical loads, as
well as the power consump-
tion by of system.
Start/stop input allows to use
a manual switch to start and
stop the system, without the
need of an auxiliary device.
The advantage of using the
latch function is that the alarm
status can be kept even after
the end of the alarm condi-
tion. Inhibit function can be
used to avoid relay operation
when not desired (mainte-
nance, transitions).
The LED's indicate the state of
the alarm and the output relay.
