SurgeX UPS+ Isolation Transformers: 

Providing surge protection and battery backup, the UPS + Isolation Transformers are built with line interactive technologies, and they couple a continuous power supply solution with power conditioning to create a complete power management solution. Available in three models — UPS-1440-Li-ISO, UPS-2200-Li-ISO, and UPS-3000-Li-ISO — the compact solutions bring all the benefits of a large-format UPS (uninterruptible power supply) to the rack-level, containing low-impedance isolation transformers that constantly filter and condition power to create a stable power environment.
