SEVENSTAR AR 1500W Voltage Regulator/Stabilizer with Built-in Step Up/Down Voltage Transformer This CE certified 1500-Watt stabilizer/transformer can convert 110/120V to 220/240V or convert 220/240V to 110/120V. Compatible with 50Hz/60Hz It can regulate input voltage from AC 75V-130V or 180V-260V to output voltage: AC 110V+-4-percent or AC 220V + - 4-percent. Meter on front shows exact output voltage This stabilizer can regulate fluctuating voltage into general voltage output. Voltage stabilizer good for countries with unstable voltage supply Two universal outlets for 220V accept plugs from most countries. Three 110V outlets for 2 or 3 pin USA plugs. On/off switch. Indicator lamp Insulated power cord wired with a European shucko plug. Heavy metal casing. Fuse protected with fuse protected with built in circuit breaker
