Features:
General Compatibility & Easy Installation: Designed with a standard modular structure and guide rail installation, this voltage monitor isuniversally compatible with ultra-wide voltage ranges, making it best for various industrial and commercial applications.
Comprehensive Three-Phase Protection: Specifically built for three-phase four-wire systems, it provides real-time monitoring of overvoltage, undervoltage, voltage imbalance, phase errors, and phase loss,guaranteeoptimal electrical safety.
Smart LCD Display & Adjustable Settings: The clear LCD screen shows voltage values, fault status, and setting parameters. Customize protection thresholds (over/under voltage, unbalance) and delay times for tailored performance.
Dual Reset Modes & Advanced Functions: Choose between automatic or manual reset options. Additional features include power-on delay, output testing, and fault record storage for easy troubleshooting.
Self-Powered & Reliable Output: No auxiliary power needed—operates directly from the monitored supply. Includes 1 changeover + 1 normally closed contact for flexible integration into control systems.
