Fully Automatic Over/Under Voltage Delay Protection Device

Self-resetting Fully Automatic Overvoltage and Undervoltage Delay Protector (JCOUV-LED-S1-D63) The Self Resetting Automatic Voltage Delay Protector is a sophisticated device engineered to safeguard electrical equipment against voltage anomalies while minimizing operational interruptions. This protector continuously monitors input voltage for both single‑phase (AC230V) and three‑phase (AC380V) systems, and upon detecting overvoltage or undervoltage conditions, it promptly disconnects the load to prevent damage. Once the voltage returns to the normal range, the built‑in self‑reset function automatically reconnects power after a user‑configurable delay (adjustable up to 30 seconds), eliminating the need for manual intervention and significantly reducing system downtime. LED indicators provide clear visual status signals for quick fault diagnosis, while optional temperature protection (trigger at ≥80°C, recovery at ≤50°C) adds an extra layer of safety in harsh thermal environments.
