EATON UPS 9E 2000i Rack 2U

The EATON UPS 9E 2000i protects servers and network infrastructure. It uses online double-conversion topology, which continuously regenerates the supply voltage and delivers a pure sine wave regardless of the input grid's condition. This online UPS achieves a high efficiency of up to 98%, thereby actively reducing operating costs and waste heat production. The compact 2U rack design (438 × 86.5 × 608mm, 29.9kg) allows for easy installation in cabinets and offers advanced battery management, plus the option to extend backup time with external modules. An integrated LCD display provides an instant overview of the unit's status and current load. The low operating noise level of under 45dB contributes to a quieter server room.

Performance and efficiency of the online topology

This UPS operates with online double-conversion topology, which continuously regenerates the input voltage and delivers a pure sine wave to the output. This completely isolates connected devices from all anomalies in the power grid. The nominal apparent power is 2000VA, while the actual available power for the load is 1800W. The very high operating efficiency in online mode, which is 98% at full load, limits energy losses and reduces cooling requirements in the server room. At half load, the unit maintains an efficiency of 97%. An internal bypass automatically switches the load to the mains in case of a UPS fault.

Battery system of the EATON UPS 9E 2000i Rack 2U

Six maintenance-free lead-acid batteries (12V / 7Ah) provide backup power. This internal system delivers a backup time of 8.5 minutes at a full load of 1800W and 23 minutes at a half load of 900W. For critical applications requiring longer autonomy, the system allows the connection of external battery modules (EBMs). Advanced battery management includes temperature-compensated charging, automatic testing, and deep discharge protection, which extends their operational lifespan. It connects to the mains via a standard IEC C14 input connector. For powering protected devices, it offers six IEC C13 output sockets, facilitating the direct connection of servers and network components.

Management, communication, and software

The unit includes RS-232 and USB ports for local and remote management. The USB port supports the HID protocol for basic control without driver installation in the operating system. It also features a mini terminal block for the remote power off (RPO) function. An expansion slot enables the installation of an optional communication card, for example, for network management via SNMP or for connecting to industrial buses. The Eaton Intelligent Power Manager and Eaton Intelligent Power Protector software provide centralised monitoring and automated, safe system shutdown.
