Three display Overvoltage and Undervoltage Protector

Three-display Overvoltage and Undervoltage Protector (JCOUV-SEG-S2-D63) The Digital Three Display Voltage Protection Relay is a state‑of‑the‑art device that integrates overvoltage, undervoltage, and overload protection with real‑time energy monitoring, all presented through an intuitive triple‑display interface. This all‑in‑one protector simultaneously shows input voltage, load current, and cumulative energy consumption (resolution 0.1 kWh) on three digital tubes, providing operators with instant visibility into system status. Adjustable protection thresholds allow users to tailor trip points for voltage and current, while flexible timing settings—including power‑on delay from 1 to 500 seconds and auto‑recovery delay from 1 to 30 seconds—ensure seamless coordination with downstream equipment. Optional temperature protection triggers at ≥80°C and recovers at ≤50°C, safeguarding the unit and connected loads in high‑temperature environments. With low power consumption under 2W and a comp…
