APC Smart-UPS SRT Tower Isolation/Step-Down Transformer

The APC SRT5KTF is an isolation and step-down transformer that pairs with a Smart-UPS or another compatible UPS to deliver clean, usable power while eliminating the inrush current and saturation issues that can trip breakers or force you into oversizing your power chain.

Because it accepts 208 to 240 volt input and can provide 120 to 240 volt output, the unit is a practical choice when you need to run mixed-voltage equipment from the same power path. Server rooms, network closets, industrial control panels, and engineering labs all benefit from the flexibility to support both higher-voltage devices and standard 120 volt appliances.

Twelve built-in outlets make connection straightforward. Eight NEMA 5-20R receptacles handle everyday IT or office hardware, while two L6-20R, one L6-30R, and one L14-30R support gear that draws more current. A three-foot line cord fitted with a NEMA L6-30P twist-lock plug lets you position the transformer close to the UPS without extra cabling.

The tower enclosure sits comfortably next to a rack or under a desk. At 125 pounds it remains stable, and its 32 to 104 degree Fahrenheit operating window covers most spaces that are climate controlled or light industrial. With a 5000 ampere peak current rating, the transformer withstands demanding startup loads and round-the-clock operation.

Use the APC SRT5KTF when you need a reliable bridge between a high-voltage UPS and a variety of downstream devices. It is a straightforward way to protect sensitive electronics, simplify power distribution, and keep your infrastructure running smoothly.
