general information

Enhanced Series - ES-C 550VA

The OPTI-UPS Enhanced Series ES550C UPS is the perfect solution for your battery backup and surge protection needs. It features three surge-protected outlets, three battery power supplied outlets, and surge-protected RJ11 / RJ45 ports. It provides pure, reliable AC power to loads such as PCs, peripherals, and electronic equipment, while protecting these loads from utility power blackout, swells, sags, surges and interferences.

Under normal power conditions, the line-interactive (AVR) design enables the UPS to adjust and filter power fluctuations continuously and automatically. In the event of power failure, it provides immediate back-up power from the built-in battery source, preventing data loss, damages and downtime. The rechargeable battery is easy to replace.
