TheLiteFuze is a step up and down voltage converter. It allows you to plug devices from higher voltage standard countries like the UK and EU (usually 220V-240V) to lower voltage standard sockets like the US (110V) and vice versa. Since it can work both ways, it's a great choice when traveling internationally.
PrimaryCurrent = Sum of o/p Volt and o/p Amp divided by Primary Volts x efficiency. The efficiency of small transformers can deviate between 0.8 to 0.§6. A value of 0.87 works extremely well for regular transformers. The appropriate wire size needs to be determined for the winding. . 483 258 359 147 276 295 280 426
