Under the umbrella of advanced power solutions, the Liebert PSI5-1000RM1201U 1000VA/900W Sinewave 1U Rackmount UPS stands out as a compact, line-interactive system with Automatic Voltage Regulation (AVR). This system is meticulously designed to cater to IT applications, including network closets and small data centers. The Liebert PSI5 UPS delivers advanced pure sine wave output on battery, ensuring the safety of critical IT equipment and business electronics. It offers steadfast power protection for servers, critical nodes, network workstations, large network peripherals, network routers, bridges, and other electronic devices. Available in three different form-factors, the Liebert PSI5 is engineered to guarantee power continuity for a diverse range of applications. It is ideally suited for servers, network closets, safety and security systems, network workstations, large network peripherals, storage, VoIP, media closet equipment, and POS systems. The compact 1U Rack Mount design is perfect for applications with limited rack space. It comes with rack mounting hardware included and Liebert Intellislot SNMP/Webcards for remote power management and environmental sensor support. The Liebert PSI5 UPS incorporates an innovative advanced line-interactive design with buck/boost Automatic Voltage Regulation (AVR) technology. This feature protects against utility voltage fluctuation by adjusting utility power to the level required by the connected equipment. It also extends battery life by maximizing its time on utility power before switching to battery. With high efficiency and 0.9 power factor operation, the Liebert PSI5 meets your critical application needs. It offers more usable power, enabling more connected loads, saving space and costs. The wider input voltage window prolongs battery life by allowing the UPS to maximize the use of utility power before transferring to battery when input exceeds specified limits (76 to 146 VAC @120V). The Liebert PSI5 UPS includes an automatic and manual self-diagnostic test feature for comprehensive battery condition analysis. It offers multiple audible and visual alarms to alert you to input voltage fluctuation (buck/boost), output overload, low battery, or replace battery condition. With up to seven battery-backed outlets, the Liebert PSI5 offers flexibility in accommodating additional equipment. The configurable input voltage window allows the UPS to be properly matched to the incoming utility power. It also features a programmable outlet group for power cycling connected equipment and load shedding on battery to extend run time. USB Communications power management functions provide monitoring of UPS status and manage the automatic orderly shutdown of the computer if a power outage ever exceeds the UPS battery capacity. The Liebert PSI5 UPS also allows for remote emergency power off during an emergency. For continuous uptime, even during scheduled UPS maintenance, the optional Liebert MicroPod Output Distribution and Maintenance Bypass Module allows you to manually transfer connected equipment to utility power. This ensures scheduled service or UPS replacement without the need to shut down connected equipment. In summary, the Liebert PSI5-1000RM1201U 1000VA/900W Sinewave 1U Rackmount UPS is a reliable, efficient, and flexible power solution for your business.
