## Long description

CyberPower OLS3000ERT2UA is a 3 kVA / 2700 W online double-conversion UPS designed to provide continuous pure sine wave power for mission-critical equipment such as NAS and servers, DVRs and surveillance systems, transportation and infrastructure devices, and emergency systems. The unit is intended for use in back offices, server rooms and data center environments. It includes a color LCD for power monitoring and configuration, relay-type dry contact for local management, and supports automatic detection of connected Extended Battery Modules (EBM) to estimate runtime. The chassis is metal and the product comes in black.
Advantages
The UPS delivers consistent pure sine wave output through online double-conversion topology, ensuring stable power for sensitive electronics. A color LCD panel simplifies monitoring and configuration, while relay dry contacts enable local control and integration with external systems. Automatic EBM detection facilitates runtime expansion without manual configuration. Variable-speed fans adjust cooling based on load to reduce noise and improve thermal efficiency. The unit features 10 AC outlets (C13 and C19) and a sealed 9 Ah lead-acid battery, providing a balance of connectivity and battery-backed runtime.
Suitable for
Server rooms and data centers
NAS devices and small to medium servers
DVRs and surveillance systems
Transportation and infrastructure control equipment
Emergency power systems and critical back-office equipment

How to use
Install the UPS in a stable, ventilated location within the recommended equipment room or rack area. Connect critical devices to the AC outlets (observe the mix of C13 and C19 connectors). Power on the UPS and use the color LCD to view input/output status and configure settings. For increased runtime, connect compatible Extended Battery Modules; the UPS will automatically detect the number of EBMs and adjust the runtime estimate. Use the relay dry contact for local alarms or integration with building management systems.
Usage recommendations
Place the unit in an environment with moderate temperature and good airflow, avoid direct sunlight and moisture. Periodically check battery status via the LCD and schedule battery replacement according to load and the manufacturer’s guidelines.
