CyberPower OLS1500ERT2UA uninterruptible power supply (UPS) Double-conversion (Online) 1.5 kVA 1350 W 8 AC outlet(s)

CyberPower OLS1500ERT2UA is an online double-conversion UPS with 1.5 kVA (1350 W) output capacity designed to supply continuous Pure Sine Wave power to mission-critical equipment. Intended for rackmount or tower installation in server rooms, back offices and data centers, the unit includes a 48 V battery, eight AC outlets and a metal enclosure. Runtime is approximately 5.3 minutes at full load and 15.3 minutes at half load, and the UPS meets CE and RoHS standards.

Advantages

The UPS provides continuous, regulated output using double-conversion topology to protect sensitive devices such as NAS, servers, DVRs and infrastructure equipment from power disturbances. A color LCD panel enables clear monitoring and easy configuration, while relay-type dry contacts allow local management integration. Extended Battery Module (EBM) auto-detection estimates available runtime when additional modules are connected. Variable-speed fans adjust thermal management according to load to reduce noise and improve operational comfort.

Suitable for

• Server rooms and data centers
• Network-attached storage (NAS) and rack servers
• Surveillance systems and DVRs
• Transportation, infrastructure and emergency systems
• Back-office equipment requiring uninterrupted Pure Sine Wave power

How to use

Install the UPS in a suitably ventilated rack or stand it as a tower on a stable surface. Connect critical equipment to the eight AC outlets and ensure the input mains supply meets the UPS rated specifications. Use the color LCD panel to view status information and configure operational settings; connect relay dry contacts if local control or alarm integration is required. If additional Extended Battery Modules are added, the unit will auto-detect them and update estimated runtime accordingly.

Recommendations

Locate the UPS in a temperature-controlled environment with sufficient airflow; avoid obstructing ventilation and keep the unit away from moisture and dust. Regularly test battery performance and replace batteries according to manufacturer guidelines to ensure dependable backup. For higher runtime requirements, use compatible Extended Battery Modules and confirm compatibility with CyberPower documentation.
