Variac Autotransformer with 30 Amp Max Output
Bench Top, Lab or Industrial Grade Variac Autotransformer with 30 Amp Max Output
Compares extremely favorably with much more expensive name brand Variac models at a fraction of the price.
This high powered, bench top Variac is one of the best and most versatile ways to precisely control AC voltage for both laboratory and industrial applications. The TDGC2-3KVA uses a typical AC input voltage of 110 volts and can adjust the output voltage to anything between 0 and 130 volts. With its high output of 30 amps, this Variac can be used for a wide array of industrial, labratory and professional applications like quality control testing, equipment testing for low and high voltage, and precise control over heat, speed, and output. This model features high effiency windings for high output and low waveform distortion, robust front panel 5-way binding terminals for output and can be used in any experiments or testing where it's required to simulate various voltage and line conditions.
While this high output 30 amp Variac is ideally suited for lab or indistrial conditions, this model is also suitable for the casual hobbyist where the uses of a Variac are surprisingly diverse. For example, auto transformers are very popular among home coffee roasting enthusiasts as it allows fine control of the temperature of the roasting of coffee beans by precicely regulating the roaster's input voltage. Vintage stereo and music equipment collectors, or collectors of any vintage electronics use an auto-transformer to feed their old, foreign or delicate equipment the exact input voltage required for proper operation when the power from the incoming 120 volt line voltage might damage it. The variable nature of the Variac allows power to be fed gradually to old or delicate electronics. In any situation where precise control of input voltage is required, the TDGC2-3KVA Variac is invaluable. This model is also extremely robust and even features replaceable brushes:
Variac Autotransformer 30 Amp Features:
One important note: the Variac does not convert AC to DC. It requires AC input and the output is AC. Also, the unit will not affect the cycle rate from the input source. If your power system is providing 60Hz, the Variac auto transformer will not change that, the ouput will be an undistorted 60Hz at the selected voltage, which can be monitored via the front panel mounted volt meter. This unit is rated up to 30 amps or 3KVA peak (at 100VAC) or (25A Continous)..
Note: Out Variacs are not compatible with most GFI (Ground Fault Interrupter) wall outlets. We have found that the inductive load that the Variac represents is not compatible with most GFI circuits and they will trip the breaker.
Note: This Variac is rated at 30 amps and most household outlets are only rated at 15 amps. Be sure to verify that the power supply you are using can deliver enough current to operate this unit.
This Variac features user replaceable brushes that can be ordered here.
For lower power or hobby uses, we also sell a 20 amp version of this Variac.
