Product Overview

The CyberPower OL8K10KRT3UTF rack/tower step-down isolation transformer converts 208V input voltage originating from utility power, a UPS, or a generator to 120V output. A 10-foot cord (NEMA L6-30P plug) connects the OL8K10KRT3UTF to input power. Over temperature protection safeguards the transformer from damage if the internal heat exceeds safe operating parameters.

The OL8K10KRT3UTF has a capacity of 5,000 Watts. It features twelve (12) NEMA 5-20R receptacles that can support output to NEMA 5-15P and 5-20P plug power cords. In addition it also has two (2) NEMA L6-20R and two (2) NEMA L6-30R outlets to power additional 208V equipment.

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