OUVR-1 Self-recovery Overvoltage and Undervoltage Protector

The OUVR-1 Self-recovery Overvoltage and Undervoltage Protector provides intelligent automatic protection for low-voltage circuits. Designed for AC 230/400 V, 50 Hz systems up to 80 A, it instantly disconnects power during abnormal voltage fluctuations and automatically restores it when voltage returns to normal. With LED status indication, a wide protection range (0 – 450 V), and 4 kV impulse withstand voltage, the OUVR-1 ensures safe, stable, and unattended operation for household and commercial power systems.

FAQs

What is the main function of the OUVR-1 protector?

It automatically disconnects the power supply during overvoltage or undervoltage conditions and restores it once voltage returns to the normal range, protecting equipment from damage.

Where is the OUVR-1 typically used?

It is designed for residential and commercial distribution boxes and other AC 230/400 V applications up to 80 A.

What happens after a fault is cleared?

The device automatically reconnects the circuit after a delay of 30 ± 10 seconds, ensuring safe system recovery without manual reset.

How does the LED indicator assist operation?

The green LED indicates normal voltage, while the red LED signals either an overvoltage or undervoltage event, making status monitoring simple and clear.

What safety and durability features does the OUVR-1 offer?

It features a 4 kV impulse withstand voltage, 50 000+ mechanical operations, and a wide 0–450 V protection range, ensuring long-term safety and reliability even under severe voltage conditions.
