Dual Overvoltage and Undervoltage Protector

Dual Overvoltage and Undervoltage Protector (JCOUV-SEG-S11-D63) Suzhou Jiangchao Electrical Technology Co., Ltd. is proud to introduce the Dual Display Over Under Voltage Protection Relay, a state-of-the-art device designed to safeguard sensitive electrical equipment from voltage anomalies and current surges. This intelligent protector belongs to the Single-phase/Three-phase Over/Under Voltage Series, offering comprehensive protection against overvoltage, undervoltage, and overload conditions with user‑adjustable thresholds for maximum flexibility. Equipped with two digital tube displays, it simultaneously presents input voltage and current values, enabling operators to monitor system status at a glance and detect potential faults proactively. The device features a built‑in temperature protection function (trigger at ≥80°C, recover at ≤50°C, optional) and programmable delays: a power‑on delay adjustable from 1 to 300 seconds (factory default 5 seconds) and an auto‑recovery delay from…
