208V to 120V Isolation Transformer Converts High-Voltage Input to Low-Voltage Output
This 3kVA 3kW SmartOnline® isolation transformer converts your UPS, utility or generator’s 208V high-voltage input to 120V low-voltage output. It features 12 NEMA 5-15/20R outlets for connecting equipment with common NEMA 5-15P and NEMA 5-20P plugs. Four resettable 20A circuit breakers protect your 120V equipment against overload conditions. One NEMA L6-20R outlet provides 208V output. 

Versatile Options for 2U Rack or Tower Installation in Your Data Center
Hardware is included for mounting this 208V to 120V isolation transformer in 2U of space in an EIA-standard 19-inch 4-post rack with a maximum depth requirement of 20.75 inches. Use the optional 2POSTRMKITWM for 2-post rack mounting or the optional 2-9USTAND for mounting in an upright tower position (both accessories sold separately). A 10-foot cord with L6-20P input plug connects to any compatible 208V 60 Hz wall outlet, UPS system or generator.
