RM series RackMount UPS systems are designed with the best space saving form factor in mind while not sacrificing any key performance of a modern UPS system. In such a small size the RM33 and RM11 series maximized the power rating up to 25kVA/kW 3phase (RM33), 10kVA 1phase (RM11). The intuitive user interface is also inherit from the MOD series for the best user experience and ease of monitor and control. All the interfacing ports are also retained for all kinds of connection needs, i.e. Network card slot, USB & RS485 ports, auxiliary volt-free contacts...etc..
