About this product

The CyberPower Smart App Online OL6KSTF rack/tower step-down isolation transformer converts 208 V input voltage originating from utility power, a UPS, or a generator to 120 V output. The included 6-foot cord (NEMA L6-30P plug to ROJ) connects the OL6KSTF to input power. Over temperature protection safeguards your OL6KSTF from damage if the internal heat exceeds safe operating parameters. The OL6KSTF has a capacity of 6,000 VA / 6,000 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.

A Three Year Warranty ensures that this device has passed our highest quality standards in design, assembly, material and workmanship.

Step-Down Transformer

The step-down transformer provides IT managers the ability to support both 120 V and 208 V output requirements. With six (6) NEMA 5-20R outlets available, users will have sufficient outlets to connect multiple 120 V devices running at 15 A and/or 20 A. If additional outlets are needed, CyberPower has a number of different Power Distribution Units (PDU) making it easy to address your specific outlet needs.
