Bronson WTI Series is designed to be an extremely robust and versatile voltage converter for both Step Up and Step Down AC voltage conversion applications. Converting European AC 230V to 110V American grid power in the Step Down mode and 110V AC American grid power to European 230V in the Step up mode. The WTI series provides pure sine wave power conversion from 3kW up to 10kW maximum continuous rating, achieving 98% by utilizing a high efficiency silicon steel toroidal core.

The Bronson WTI Series provides current overload protection on both 110V and 230V inputs as well as on each output socket. Inputs & Outputs can be easily wired using the terminal connections and additional output sockets are available for EU Schuko, UK, and grounded USA Nema plugs. Multiple AC power appliances may be connected to the 110V or 220V sockets using a power strip so long as the total combined wattage ratings of all connected appliances do not exceed 16A rating of the sockets, the bolt terminals will support continuous loads corresponding to the maximum watt rating of the converter. The Bronson WTI series features a mounting bracket that allows it to be vertically wall mounted or horizontally fixed down for motion sensitive installations like RV’s

Please note that WTI Series voltage converters will convert only the AC voltage and not convert the AC frequency (Hz) between 50Hz and 60Hz and so may not be suitable for all applications. Please check with the maker of your load devices to ensure compatibility with both 50Hz and 60Hz power supply.
