With pure sine wave output, the Commander Rackmount Tower guarantees compatibility for all kinds of loads. It’s perfect power protection for versatile applications such as networking, telecom and other mission-critical applications. The ECO mode function allows cost-effective operation of UPS Systems as high as 98%. In this operation mode, load is supplied by the mains.
