3000 Watts maximum capacity Converts 110/120 V to 220/240 V OR converts 220/240 V to 110/120 V (switch is on back of unit) This can also be used just as a power regulator with Input of 220 Volt and output of 220 Volt and vice versa Compatible with 50Hz/60Hz. This stabilizer can regulate big range fluctuating voltage into general voltage output. Input Voltage AC 75V-130V or 180V-260V. Output Voltage: AC 110V+-4% or AC220V+-4%. On/Off switch with indicator lamp Analog meter on front of unit shows exact output voltage Voltage stabilizer good for countries with unstable voltage supply 4 outlets on front of unit Two universal outlets for 220V accept plugs from any country except the big S.Africa plug Two 110V outlets accept 3 or 2 prong US plugs and 2 prong Euro/Asian plugs. There is a input selection switch at the rear of the unit. Regardless of what input voltage is selected, you will get regulated 110V/120V power coming out of 110V outlets and regulated 220V/240V power coming out of 220V outlets. Connect the devices that require 220V to 220V outlets and 110V devices should be connected to 110V outlets. Insulated power cord is hard wired with a European Shucko plug also good for Asian outlets (grounded 3 prong US adapter also available - Item No. VP 13) Heavy-duty metal casing and durable design Comes with round and flat pin plugs for use in USA, Canada, and Mexico Fuse protected with Built in Circuit Breaker CE Certified
