Winsted now offers a number of UPS systems that deliver reliable protection from electrical problems for any application. The Winsted PRO-E Series UPS are amazingly compact. A built-in double-boost and single-buck automatic voltage regulator (AVR) function compensates for broader range of low ac-voltage situations as well as high ac-voltage, saving internal batter power for blackouts and extending battery life. These units are available in 500, 700, 1100 and 1500-VA versions. The Winsted SmartSine UPS series offers True Sinewave UPS and line-interactive topology with rich features and a compact design all at an affordable price.
