## Long description

CYBERPOWER OLS3000ERT2UA-B is an online double-conversion uninterruptible power supply with a rated capacity of 3 kVA / 2700 W. Designed for continuous protection of servers, networking equipment, NAS, DVR and other mission-critical IT devices, it delivers pure sine wave output with zero transfer time. The unit comes in a convertible rackmount/tower metal housing, includes ten AC outlets (combination of C13 and C19), uses sealed lead‑acid (VRLA) batteries (72 V, 2 units) and provides a color LCD for local monitoring and configuration. The UPS supports generator operation, external extended battery modules for extended runtime, and power management software for remote monitoring.
Advantages
