APC SRT5KRMTF Rack-Mount Step-Down Transformer

The APC SRT5KRMTF Rack-Mount Step-Down Transformer is a rack-mount power transformer that converts high-voltage UPS output from APC Smart-UPS SRT systems to 120V for connected equipment, delivering 5000 VA (5 kVA) in a 3U enclosure. It accepts 208V or 240V AC input via a hardwired connection and provides 120V AC at the output through multiple NEMA 5-20R outlets, making it suitable for data centers, enterprise server rooms, and IT infrastructure cabinets that require voltage conversion for mixed-voltage devices. Designed to work with APC Smart-UPS SRT 5kVA models, the unit uses passive cooling with internal thermal protection to maintain safe operation under load. Common replacements include SURT003 Smart-UPS RT Step-Down Transformer as part of APC's Smart-UPS SRT accessories lineup.
