Product Description
Ordering key
DWB 01 C M48 10A
DWB01 and PWB01 are precise TRMS power factor monitoring relays for 3- phase balanced systems. They can be used for moni- toring the actual load of asynchronous motors and other symmetrical loads, where the power factor is almost proportional to the load.
The relay measures the power factor (cos ϕ), that is the ratio between the active and the apparent power of a motor.
Start/stop input allows to use a manual switch to start and stop the motor, without the need of an auxiliary device.
The advantage of using the latch function is that the relay can be kept energized even after the end of the alarm condition. Inhibit func- tion can be used to avoid relay operation when not desired (maintenance, tran- sients).
The LED's indicate the state of the alarm and the output relay.
