DETAILED DESCRIPTION

DWB03.. & PWB03..

TRMS active power monitoring relay for 3-phase balanced systems.
They can be used for the current load of asynchronous motors and other symmetrical loads, as well as to see if the power flows in the correct direction.
The start / stop input allows to use and manual switch to start and stop the system, without the need of an auxiliary device.
The advantage of using the latch function is that alarm status can be kept even after the end of the alarm condition.
The LEDs indicate the state of the alarm and the output relay.
