The SF8RM is designed to protect equipment against power surges & electrical noise whilst providing a convenient combination of power outlets to suit most applications. A unique mounting system allows mounting in many different modes to suit crowded racks. Even if no rack space exists, the units may be mounted externally on the front or rear of the rack. For horizontal mounting, the units require a single 1RU rack space for installation. The unit may also be flush mounted to either side of a rack or cabinet.
