Product details

The CyberPower OLS4KERT4UA-IEC is a highly efficient UPS in an online double-conversion topology, providing seamless pure sine wave power for mission-critical devices such as NAS and servers, DVRs/surveillance systems, infrastructure, and emergency systems. It is typically integrated into server room and small data center applications.

The UPS offers a high output power factor with a smaller footprint, allowing for more usable power and saving rack space. The intuitive, tiltable LCD color display enables the user to easily monitor and configure settings. This product can automatically detect the number of connected external battery extension modules (EBM) to calculate the UPS runtime. Additionally, the battery charging current can be adjusted via the LCD settings to reduce charging time. It is also equipped with a relay contact connection that supports specific UPS event notifications for easy management with building systems. Furthermore, the PowerPanel Business energy management software provides real-time monitoring and configuration.
