FAQs

What is the purpose of the OUVR-2 Self-recovery Overvoltage and Undervoltage Protector?

It safeguards equipment by disconnecting power during unsafe voltage conditions (over or under) and automatically restoring it once the voltage stabilizes, ensuring continuous and safe operation.

Where is the OUVR-2 typically used?

It’s ideal for household distribution boxes, small commercial systems, or industrial control panels requiring stable power supply and unattended recovery.

How does the LED indication system work?

The green LED signals normal voltage, while the red LED lights up during overvoltage or undervoltage events, providing a quick status overview.

How long does it take to recover after a voltage fault?

The device reconnects automatically after 30 ±10 seconds once the voltage returns to the safe range (196V–253V).

What makes the OUVR-2 reliable?

Its inverse time-lag operation (<1s), 50,000-cycle lifespan, and 4kV surge withstand capability make it a durable, low-maintenance choice for reliable power protection.
