CyberPower OLS4KERT4UA-IEC is a highly efficient UPS in online double conversion Topology that provides 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 at lower footprint, providing more usable power and saving rack space. The intuitive, tiltable color LCD display allows the user to easily monitor and configure settings. This product is able to automatically detect the number of external battery expansion modules (EBM) connected to calculate the UPS running time. In addition, the battery charging current is adjustable via the LCD setting to shorten the charging time. It is also equipped with a relay contact port that supports specific UPS event notifications for easy management to building systems. In addition, the PowerPanel Business energy management software offers real-time monitoring and configuration. Features
