I have a refurbished UPS (uninterrupted power supply) battery backup for sale. This is a refurbished unit with brand new batteries installed. This is a true online double conversion power supply. Meaning it converts line power to DC then back to clean AC, therefore truly isolating your electronic components from wall power. This is the best protection type available. Therefore it is more expensive than other UPS you see on the market (those that SWITCH to battery quickly when power goes out).
