Uninterruptible power supply CYBERPOWER OLS6KERT5U Double-conversion (Online) 6 kVA / 6000 W, 9 AC outlets, Tower, Black

CYBERPOWER OLS6KERT5U is a double-conversion (online) uninterruptible power supply (UPS) delivering Pure Sine Wave output with 6 kVA / 6000 W capacity. Designed for continuous protection of mission-critical equipment such as servers, NAS, DVRs and surveillance systems, the UPS fits tower or rack/room environments and provides nine AC outlets. The unit uses sealed lead‑acid (VRLA) batteries and offers typical runtime of approximately 5.6 minutes at full load and about 17.7 minutes at half load.

Advantages

The UPS employs online double-conversion topology to provide stable, high-quality power for sensitive IT and infrastructure loads. A high output power factor delivers more usable power in a compact footprint, helping to save rack space. Units can be paralleled to increase capacity and achieve power redundancy. A pre-installed maintenance bypass PDU enables safe service without interrupting power. Integrated remote monitoring via a cloud card and a tiltable color LCD with graphical interface simplify configuration and status monitoring. Battery charging current is adjustable through the LCD to reduce recharge time, and a relay-type dry contact port provides event notifications for integration with monitoring systems.

Suitable for

• Server rooms and data centers
• Network equipment and NAS
• DVRs and surveillance systems
• Infrastructure and transportation control systems
• Emergency and mission-critical systems

How to use

Install the UPS in a stable, ventilated location suitable for a tower unit or within a rack/room placement. Connect critical devices to the AC outlets according to their power requirements and ensure the total load does not exceed the rated 6000 W. Use the tiltable color LCD to view operating status and adjust settings, including battery charging current. Configure remote monitoring by installing and registering the supplied Remote Cloud Card to enable web-portal and mobile app access. If multiple units are used, follow manufacturer instructions to connect UPS units in parallel for increased capacity and redundancy. For maintenance, use the pre-installed Maintenance Bypass PDU to isolate the UPS without interrupting power to connected equipment.

Recommendations

Place the UPS in a temperature-controlled environment, maintain clear airflow around the unit, and follow the manufacturer’s service intervals for battery inspection and replacement. Verify outlet types and ensure connected equipment cabling matches the UPS outlet configuration. When paralleling units, perform configuration and verification steps per CyberPower documentation to ensure correct load sharing and redundancy.
