Product Features
Technical Overview
This line-interactive UPS features buck/boost AVR technology that corrects under-voltage and over-voltage conditions without switching to battery, extending battery life and reducing wear. The pure sine wave output ensures compatibility with active PFC power supplies found in modern servers, networking gear, and storage devices.
Communication and control are facilitated through an integrated LCD display, USB HID-compliant port, network RJ-45 interface, and EPO (Emergency Power Off) port. The unit supports up to six external battery cabinets, enabling runtime extensions up to 2.57 hours at full load and 5.83 hours at half load when expanded.
This section brings together practical product details such as AVR, Plug/Connector Type, Receptacle Type, Load Capacity (VA), so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
