The Episode® Power UPS (EP-400-UPS-8PS-825) and surge protection product line was specified and designed with the installer in mind. Whether your working on a home theater or a whole house system, this model has the features most requested in the industry. We took a commercial UPS product and stuffed it with the essentials for an audio, video, and whole house system integration installation. For example, this unit comes with automatic voltage regulation, a stronger battery than the commercial grade, and AC outlets, spaced for transformer plugs, that can handle 825VAC. We've added keyhole mounting slots and enlarged the LCD display for easy visibility behind equipment and entertainment centers. Plus the assurance of 1030 Joules of surge/lightning protection, backed with our protection guarantee. Keep equipment operating safely with a UPS power strip with AVR. This unit will automatically provide battery back-up power if the line voltage drops below 90 volts and will decrease output voltage if the line voltage exceeds 140 volts.
