Uninterruptible Power Supply CYBERPOWER OLS1000EA, Online double-conversion, 1 kVA/900 W, 3× IEC C13 outlets, pure sine, LCD, tower

The CyberPower OLS1000EA is a 1 kVA online double-conversion UPS that delivers pure sine wave output and 900 W continuous power for critical equipment. Housed in a black metal tower enclosure, it includes a sealed lead-acid battery and three IEC 320 AC outlets. Typical backup time is about 4 minutes at full load and 11 minutes at half load. The unit is generator-compatible, CE- and RoHS-compliant, and intended for use in back offices, server rooms and data centers to protect NAS, servers, DVRs/surveillance systems, transportation and infrastructure devices, and emergency systems.

Advantages

The OLS1000EA uses online double-conversion topology to provide uninterrupted pure sine wave power and tight voltage regulation. A color LCD panel offers real-time monitoring and simple configuration. Built-in ECO mode reduces power consumption when conditions allow, and compatibility with generators expands deployment options. An Emergency Power Off (EPO) input enables immediate shutdown in critical situations, while variable-speed fans manage thermal conditions and lower audible noise.

Suitable for

• Small server rooms and data centers
• NAS and enterprise storage devices
• DVRs and surveillance systems
• Transportation and infrastructure equipment
• Emergency power systems

How to use

Install the UPS in a ventilated area on a stable surface and connect critical devices to the IEC 320 outlets. Use the color LCD panel to view input/output voltages, load level and battery status, and to configure operation modes including ECO mode. If a generator is used, confirm generator compatibility before switching sources. Connect the Emergency Power Off (EPO) switch according to the supplied wiring diagram to enable remote shutdown when needed.

Recommendations

For reliable operation, perform periodic battery tests and replace the sealed lead-acid battery according to the maintenance schedule. Keep the unit free of dust, allow sufficient airflow around the enclosure, and avoid placing the UPS in environments with extreme temperatures or high humidity.
