The CyberPower Smart App Online OL10KSTF rack/tower step-down isolation transformer converts 200 V to 240 V input voltage originating from utility power, a UPS, or a generator to 120 V output.

The OL10KSTF has a capacity of 10,000 VA / 10,000 Watts. It features six (6) NEMA 5-20R receptacles that can support output to NEMA 5-15P and 5-20P plug power cords. A hardwire output terminal block provides a means to connect to an electrical subpanel.

The included 3-foot power cable kit (6AWGHW3FT) connects the OL10KSTF to input power. Over temperature protection safeguards your OL10KSTF from damage if the internal heat exceeds safe operating parameters.

A Three-Year Warranty ensures that this step-down transformer has passed our highest quality standards in design, assembly, material or workmanship.
