Digital Monitoring Relay for Automatic Phase Sequence Correction
1 / 2
Manufacturer catalogue image
Product Description
RoHS CompliantLifecycle Status:Successor:
This digital monitoring relay is specifically designed to handle the complexities of 3-phase voltage systems. It features automatic correction of phase sequences, ensuring that your system remains stable even during phase failures. The relay operates within a voltage range of 90 to 400 V at frequencies of 50 to 60 Hz. It also includes undervoltage and overvoltage protection with a hysteresis of 1-20 V, switch-off delay of 0-20 s, and asymmetry of up to 20%. The relay is equipped with screw terminals for easy installation.
The relay also includes two current outputs (CO), one for phase correction and another for line supply faults. This allows for efficient management of your power system, ensuring that any faults are quickly identified and rectified. With its robust design and advanced features, this digital monitoring relay is an essential component for maintaining the reliability and efficiency of your 3-phase voltage systems.
