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.
