Emerson HRS1150-9000 Telecom DC power system (rectifier shelf) Power Supply

The Emerson HRS1150-9000 is a 48V DC rectifier module rated at 1150W, designed for plug-in installation in telecom DC power system shelves. It accepts an AC input of approximately 200 to 240V at up to 7A and converts it to a regulated 48V DC output of up to 20A, feeding the DC busbar that powers connected telecom and networking equipment. Rectifier modules of this type are commonly deployed in mixed-vendor power rooms and cabinets, including sites built around Huawei access, transmission and switching platforms that share a common -48V DC power plant. As a hot-swappable module, the HRS1150-9000 can typically be replaced without powering down the rest of the rectifier shelf, making it a common item for maintaining N+1 redundancy in existing DC power systems. This is a legacy rectifier component, used to maintain, repair or expand existing DC power installations. Tech-Star (UK-based, shipped worldwide) stocks legacy rectifier hardware including this module. Get in touch with your power shelf and site details to confirm compatibility before ordering.
