A UPS is a device that acts as a defensive barrier between electronic equipment and incoming power problems. It conditions, regulates, and filters out power disturbances to ensure a clean power source for IT equipment. A UPS also provides battery backup if there is a power failure.

In today’s high availability server environments, unplanned power outages or line quality irregularities can have a considerable financial impact on all sized businesses. The typical utility power is 99.9% available, but that means that there can be almost 9 hours of downtime a year, not to mention brownouts and other power quality problems. 

Uninterruptible power system (UPS) protects your sensitive electronic equipment from the most common power problems, including power outages, voltage sags, impulsive transients, line noise, and long-term under and over voltage conditions.

Power outages can occur when you least expect it and power quality can be erratic. These power problems have the potential to corrupt critical data, destroy unsaved work sessions, and damage hardware - causing hours of lost productivity and expensive repairs.

Selecting the right UPS can help protect against these potentially costly incidents.

The RT1.5kVA and RT3kVA 2U Rack or Tower UPS-G2 units are most effective against power failures, power sags, power surges, under-voltage, and over-voltage.

The RT1.5kVA and RT3kVA 2U Rack or Tower UPS-G2 models offer the following features:

• High-efficiency protection for more real power (Watts) in a compact tower or 2U rack design, which lowers power and cooling consumption
• A graphical Liquid Crystal Display (LCD) that provides intuitive configuration, management, and monitoring capabilities in the following languages to reduce management complexity:
  • Chinese
  • English
  • French
  • German
  • Italian
  • Japanese
  • Portuguese
  • Spanish
  • Russian
• Hot-swappable batteries for maximum uptime, availability, and ease of maintenance
• Subscription based Intelligent Power Manager (IPM) Software seamlessly integrates with leading virtualization environments and cloud orchestration tools. IPM provides effective local or remote power monitoring and management for servers and virtual machines and allows for graceful remote system shutdown
• ABM technology that significantly extends battery service life by up to 50% and optimizes recharge time
• Load segments for individual control of receptacle groups to manage sequential shut downs and start ups and reserve battery run time for the most critical equipment
• Optional Extended Battery Module-G2 (EBM-G2) that provide extra run time to critical systems during a prolonged power outage
• An optional NMC for enhanced UPS monitoring and control over-the-network through a standard web browser
• An optional EMP for thermal management requirements (temperature and humidity)
• Dual channel communication through the USB or RS-232 port and an optional NMC at the same time to maximize communications flexibility
• The USB port supports HID (Human Interface Device) Power Device Class which means that the UPS can be directly managed by operating systems that support such USB classes.
• Remote flash upgradeable firmware for the UPS and NMC, which makes it an ideal solution for remote locations
• An ROO/RPO port to control power of the UPS unit through a wired remote switch
