Sound House's UPS (uninterruptible power supply) corner has a lineup of 5 models ranging from a rectangular wave output model with excellent cost performance to a sine wave output type to build a safer backup environment. The LX and PSII series employ a highly efficient line interactive method and are equipped with an AVR (automatic voltage correction function). The UPS1000RT is a high-level model that uses a constant inverter system that always supplies power at a stable voltage. The included power management software can be set to automatically shut down your equipment when a power failure occurs, and to set up e-mail notification when an event occurs. Be sure to check out the feature page that shows the features, specifications, and selection methods of each model.
