Know before you buy
Double conversion topology continuously converts incoming AC power to DC and back to clean, regulated AC power. This process ensures that your mission-critical equipment receives a pure sine wave output with zero transfer time during a power failure, providing the highest level of protection against voltage fluctuations.
Yes, this unit features hot-swappable batteries, allowing you to replace them while the UPS continues to provide power to your connected equipment. This design is essential for maintaining uptime in enterprise environments where constant availability is required.
At full load (1200W), you can expect approximately 4.7 minutes of runtime. If you are running at half load (600W), the runtime increases to about 13.5 minutes, giving you enough time to safely save work or initiate a graceful shutdown.
Yes, it uses a standard NEMA 5-15P plug and provides eight NEMA 5-15R outlets, making it compatible with standard 120V wall receptacles found in most offices and server rooms.
Yes, it includes SNMP and HTTP remote monitoring capabilities. This allows IT administrators to manage and monitor the UPS status over a network, providing better visibility into power health and battery status.
ECO mode is an energy-saving feature that improves efficiency to over 96% by bypassing the double-conversion process when utility power is stable. It helps reduce electricity consumption and heat output during normal operating conditions.
