PowerWalker VI 2200-3000 RLE is a compact line-interactive series with rack design. The unit provides Pure Sine Wave output with voltage regulation, offering optimal protection for small motor-based loads and servers with APFC power supplies. The USB port features HID support, which allows native communication with nearly all common operating systems - removing the need for installing additional software. Improved internal heat dissipation makes sure the UPS runs silently during standard operation. A comprehensive LCD panel provides all the necessary information and will auto-dim after a few seconds. These features make the UPS series an attractive solution for home use as well.
