Product Overview

The DWB01 series 3-phase load guard Monitoring Relay with precise TRMS power factor for 3-phase balanced systems. It can be used for monitoring 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 function can be used to avoid relay operation when not desired (maintenance, transients). The LEDs indicate the state of the alarm and the output relay.
  • Measuring if the power factor is within set limits
  • Measures own power supply
  • Separately adjustable upper/lower level on absolute scale
  • Programmable latching or inhibit at set level
  • LED indication for relay, alarm and power supply ON
  • Power ON delay 1 to 30 sec knob adjustable
