UPS CYBERPOWER OLS1000ERT2UA-B On-Line 1000VA/900W 2U Tower/Rack LCD USB RS232

CYBERPOWER OLS1000ERT2UA-B is an On-Line uninterruptible power supply with 1000VA / 900W output capacity designed to provide continuous, double-conversion power protection for critical IT equipment. The unit's 2U chassis supports both tower and 19" rack mounting and includes an integrated LCD for real-time status and configuration. Communication interfaces include USB and RS232 ports to enable monitoring, event logging and controlled shutdown of connected systems. The on-line topology delivers consistent sine-wave output and isolates sensitive devices from input power disturbances.

Advantages

The on-line double-conversion design ensures stable, clean power without transfer time during mains disturbances. Its 2U form factor offers flexible installation options for racks or standalone deployment, while the LCD provides clear operational information at a glance. Built-in communication ports support remote monitoring and safe, orderly shutdown procedures. The unit is suitable for continuous operation in environments where power quality and availability are essential.

How to use

Install the UPS in a 19" rack or place it on a stable surface in tower orientation according to the facility layout. Connect the UPS to a grounded mains outlet that meets the unit's voltage requirements. Attach critical devices to the UPS output sockets, and connect the USB or RS232 cable to a management server or workstation to enable monitoring and shutdown features. Use the front-panel LCD to view real-time status, configure basic settings and review event logs. For battery-backed shutdown, configure the connected management software to perform graceful shutdowns when battery runtime reaches the required threshold.

Recommendations

Locate the UPS in a ventilated environment away from direct heat sources and moisture. Regularly test battery runtime and perform periodic firmware or software updates for monitoring tools. Ensure connected equipment draws within the rated 900W continuous load and plan for additional capacity if powering multiple devices. Maintain a service and battery replacement schedule based on runtime measurements and manufacturer guidelines.
