Variable Voltage Transformers
Tempco's Variable Transformers provide a simple rugged method of controlling electrical voltage current and power. They take in utility line voltage and provide continuously adjustable output voltage. A wide range of sizes drives enclosures and controls is offered. Standard fixed ratio transformers have output terminals connected to a particular turn of the coil to provide a given output voltage. Instead of a fixed connection to a particular turn of the coil Tempco's Variable Transformers utilize a brush riding on a commutator formed as part of the transformer turns. The user can select any output turn ratio and thereby vary the output voltage. Because they are autotransformers one winding acts as both the primary and secondary coils of the transformer |

| How To Order | |
| Standard Transformers | Other Transformer Models |
| Choose the Part Number of the Variable Voltage Transformer that matches your requirements for voltage
amperage
and phase.Make certain that the construction type matches your
application needs as some units have an open construction that can only be used in panel
mounting applications--see the pictures above to identify the construction.
Standard lead time is Stock to 10 days. |
Other models are available; consult Tempco. Please contact Tempco for further assistance.
