Fully Automatic Over/Under Voltage Delay Protection Device

Self-resetting Fully Automatic Overvoltage and Undervoltage Delay Protector (JCOUV-LED-S1-D63)   Advantages   This protector delivers reliable voltage stability and automatic recovery, effectively shielding electrical equipment from damage caused by overvoltage or undervoltage anomalies. Its self-resetting function eliminates manual intervention after voltage normalization, minimizing downtime and ensuring continuous, safe power supply for critical systems.   Detailed Features   Designed for both single-phase (AC230V) and three-phase (AC380V) systems, it offers precise overvoltage and undervoltage protection with adjustable thresholds. LED indicators clearly signal fault status for quick troubleshooting. Key features include optional temperature protection (triggers at ≥80°C, recovers at ≤50°C), a 30-second self-reset delay, and low power consumption (<1W for single-phase, <2W for three-phase). The compact design supports standard 35mm DIN-rail mounting, enabling easy integratio…
