Uninterruptible Power Supply CYBERPOWER OLS2000ERT2UA-B 2000VA/1800W On-Line Tower/2U with LCD, USB and RS232

The CYBERPOWER OLS2000ERT2UA-B is an on-line uninterruptible power supply with 2000VA/1800W capacity, designed for tower or 2U rack installation. It uses continuous double-conversion topology to deliver regulated AC output and battery backup for servers, network hardware and sensitive electronic equipment. The unit includes a front-panel LCD for real-time status and basic configuration, USB and RS232 ports for monitoring and integration with shutdown software, and provides steady power conditioning to protect connected devices from outages, voltage fluctuations and frequency variations.

Advantages

This on-line UPS offers continuous double-conversion protection that isolates loads from utility power disturbances, supplying a consistent sine-wave output and uninterrupted operation during mains failures. The front LCD presents operational information and settings in a clear format, while USB and RS232 communication interfaces enable monitoring, logging and orderly shutdown of connected systems. The tower/2U form factor supports flexible deployment in both small rack environments and standalone locations.

Suitable for

• Small to medium IT racks hosting servers and network switches
• Workstations and sensitive electronics requiring clean, continuous power
• Environments where remote monitoring and graceful shutdown are needed
• Telecom closets and point-of-sale systems that need battery backup

Key specifications

• Topology: On-line double-conversion UPS providing continuous AC regulation
• Rated capacity: 2000VA / 1800W
• Form factor: Tower or 2U rack-mountable
• User interface: Front-panel LCD for status and configuration
• Communications: USB and RS232 ports for monitoring and control
• Output waveform: Regulated sine-wave suitable for sensitive equipment

How to use

Install the unit in a stable, ventilated location as a tower or mount it in a 2U rack shelf according to rack installation guidelines. Connect critical equipment to the UPS output outlets and use the front LCD to check status and configure basic settings. Attach the USB or RS232 cable to a host computer to enable monitoring software and configure automatic shutdown procedures to occur on extended mains failure. Ensure the UPS batteries are charged by leaving the unit connected to AC mains prior to reliance on battery backup.

Recommendations

Place the UPS away from direct heat sources and moisture; allow clear airflow around the chassis. Regularly verify battery status from the LCD or monitoring software and schedule battery replacement according to runtime needs and load profile. Use the provided communication interfaces to integrate the UPS with server management or shutdown tools for reliable, unattended operation.
