APC Step-Down Transformer RM 2U 208V IN 120V OUT w/L5-20 Receptacles

The APC AP9627 is a rack-mountable step-down transformer that converts a 208-volt power feed to a steady 120-volt output, making it simple to run standard equipment in facilities that distribute higher-voltage power. It occupies only 2U of rack space, so it slides neatly into existing server racks without forcing a shuffle of other gear.

With a 5000 VA load capacity and 90 percent efficiency, the transformer delivers enough headroom to support servers, networking switches, storage arrays, or lab instruments that rely on 120 volt input. Four NEMA L5-20R receptacles are positioned on the rear panel, giving you direct, high-quality connections for multiple devices. A factory-installed 2-foot cable with a NEMA L6-30P plug ties the unit into a 208 volt branch circuit in moments, which helps keep installation time short during maintenance windows.

APC includes an integrated circuit breaker that guards connected equipment against overloads. The transformer carries UL 1778 and CSA certifications, so you can deploy it with confidence in sites that require documented safety compliance. It operates in environments ranging from 32 to 104 degrees Fahrenheit and up to 95 percent humidity, a range wide enough for typical data centers, network closets, and industrial control rooms.

IT managers often choose the AP9627 when they need to add standard 120 volt gear into a rack that is already wired for 208 volt distribution. It is equally useful for temporary test setups where engineers may swap equipment in and out, or for colocation cabinets where different clients run varied hardware. At 95.2 pounds, the chassis has the heft expected from a transformer of this rating, yet it ships with mounting brackets that simplify secure installation.

Whether you are expanding a midsize data center, equipping a disaster-recovery site, or setting up a branch office lab, this transformer offers a practical path to consistent 120 volt power without re-wiring the entire electrical infrastructure.
