Variac Transformer Home                          Resources and information on variac transformers are listed. Learn about the different applications and what a variac transformer can do.

3 Phase Variac Transformer                         A 3 phase variac transformer will have 3 windings that are connected in a sequence that will match the incoming power. This will transform the power companies voltage to the level that is needed. 

Variac Transformer Amps                                   is also called current as it is the amount of electric energy that is flowing through the variac transformer. The amps is the amount of electricity that is pulled from the voltage in the line.

Variable Voltage                Learn how to adjust output voltage from 0 to 117 percent of the units input voltage. A variac transformer would be the way to go. 

Variac Wiring                     The inductor on a variac transformer is shaped like a doughnut with wire that is wrapped through the center hole. Due to the resistance of the winding wire, heating can sometimes be present.  
 

Single Phase Variac Transformer                       This type of variac transformer is mainly used on lighting and heating loads. They can either be air cooled or oil cooled.
 

Isolation/Variac Combination                     An isolation/variac combination type of transformer will isolate sensitive equipment from electrical noise and interference from the AC power line. It is used quite often in testing functions.  

Variac Auto Transformer                       This type of transformer will either act like a step-up or a step-down transformer. A variac auto transformer will not provide isolation from any line current.

TEMCo Variac Transformers

TEMCo variac transformers are the best selling in America. TEMCo variac transformers are state of the art  and are offered at very reasonable prices. TEMCo carries a wide range of models and brands of variac transformers.

TEMCo variac transformers are used to provide an adjustable voltage in many different applications throughout the industry. TEMCo variac transformers are available in different types like the bench model and the open frame model. The bench model of a TEMCo variac transformer will contain a winding in a ventilated metal shield and will usually have a control knob either on the top of the side of the device. The bench model TEMCo variac transformer will have a plug in cord and sometimes they will have a current or voltage meter installed on them. The TEMCo variac transformer that comes in the open frame model are intended to be panel mounted in equipment racks.  Sometimes the TEMCo variac transformer becomes part of larger equipment. The TEMCo variac transformers are intended to work for a specific input voltage and frequency and only the output will become variable.

TEMCo variac transformers are made from the highest quality materials available. All of the wiring on the variac is insulated which is better for transferring heat.  TEMCo variac transformers work as a tapped inductor. The inductor of a variac is the core of the transformer that is shaped like a doughnut. The insulated wiring is wrapped tightly around the core and through the center hold of it. The wires on the TEMCo variac transformers are not only insulated but are layered with enamel covered magnet. Each end of the wire is fastened securely to the winding of the core. The TEMCo variac transformers will have a slider arm or brush that is equipped with a carbon contact that will rotate around a track that is located through the hole of the core. When the TEMCo variac transformer wire touches the contact arm or brush, the enamel insulation is removed at that time. This contact will form a circuit through part of the windings. Almost all of the power that is consumed when using a TEMCo variac transformer, will be delivered to the load that is connected to the output.

Many years of experience go into the TEMCo variac transformers. This company has been in business since 1968 and they are a manufacturer and supplier that you can trust.
