SEYAS 500W AUTO STEP UP & STEP DOWN VOLTAGE TRANSFORMER CONVERTER

Automatic Voltage Conversion Technology In the past, you have to select the input voltage (by the selector) manually. If the transformer not properly set,it could cause damage the transformer itself and the device trying to power off. SEYAS Automatic Voltage Conversion Technology makes the transformer safer and easily use,it can detect the input voltage and convert to the corresponding you need (U.S.Patent No.US9225259 B2.) 100% Full Load Capacity This latest high level voltage transformer can be used in 110 volt countries and 220 volt countries,It will convert from 220-240 volt to 110-120 volt AND from 110-120 volt to 220-240 volt 50 60 Hz, The Universal 220v Output Socket will accept all types of plugs except the Big South African plug. Provided 100% FULL Load Capacity. Make sure the total starting power does not exceed the maximum capacity of the converter. 7x24hrs Continous Run High efficiency toroidal transformer with stable output and low consumption. With Temperature Rise Test and IEC test report. NOTE: This converter is designed only for European/Asian 220V (Single Phase), and will not Work with American 220/240V (Dual Phase). WARNING: We recommend 3X efficiency factor for high wattage heat producing items such as Air Condition, Welding Equipment etc.
