Emerson 3500W ultra-high-efficiency eSure rectifier (model R48-3500E4) is designed with next-generation gallium nitride (GaN) technology to optimize energy efficiency and lower operating cost, while delivering the proven reliability you've come to expect from the eSure portfolio. GaN technology enables a combination of superior efficiency and world-class density. This eSure rectifier offers a flat efficiency curve to optimize energy savings at any load condition. When upgrading your network to 98% efficiency, one important factor to consider is the shape of the efficiency curve. Emerson R48-3500E4 delivers superb efficiency from 20 to 100% load. In order to maximize efficiency and energy savings, the system should operate at a load point that coincides with peak efficiency. To lower investment and optimize energy savings even further, Vertiv offers ECO mode functionality in the NetSure control unit. ECO mode enables you to put lower efficiency rectifiers in stand-by mode when load conditions are normal. When more powers are needed during peak load, battery recharge and some other reason, the controllers activate as many rectifiers as necessary. Mixing standard and high-efficiency rectifiers help balance the cost of upgrades. Whether you're upgrading a core site with large power needs or multiple access sites that require less power, upgrading your infrastructure to 98% efficiency can make a big impact on the environment and your bottom line.
