Low Cost Benchtop Variac Auto Transformer, 5 Amp Max Output
A Handy item for any bench, this Variac auto transformer is extremely efficienct and imparts no waveform distortion. Rated at 110V input with an output voltage between 0 and 130 volts. Maximum output current is 5A with a capacity (KVA) of 0.5. This Variac- auto transformer is used to either raise or lower the AC voltage that enters it. The output is also AC and it does not affect the cycles. So if you had a 130 volt AC input at 60 Hz, you could plug in this auto transformer and change the AC from 130 volts to anything between 0 and 130 volts (depending on your requirements). The 60Hz cycle would not be affected.
This auto transformer is VERY popular for home coffee roasting. It allows much greater control of the temperature of the roasting of coffee beans. They can also be used in science lab, audiophile (Great for old tube amplifiers), science lab, hobby, film or video lighting applications.
Please note that Variacs are not compatible with most GFI (Ground Fault Interrupter) wall outlets. Because the load is very inductive, the Variac represents a fault and is not compatible with most GFI circuits or outlets.
This Variac does not convert AC current to DC current. It requires an AC input and provides an AC output. Also, as mentioned above, this model will not affect the cycle rate from the power company. If your power system is providing 60Hz, the Variac auto transformer will not change that, the ouput will be an undistorted 60Hz. This unit is rated up to 5 Amps or 0.5KVA.
Note the output of this Variac is only 5 Amps. For more power intensive applications we have 20 and 30 amp models.
