Applications

Used in telecommunications and industrial test environments for voltage regulation during equipment diagnostics and power supply validation. Variac-type transformers serve as general-purpose AC power sources for component testing, circuit characterization, and fault simulation on three-phase and single-phase systems. Commonly deployed in manufacturing test floors and service centers for conditioning incoming power to test setups.

Condition: Used
This General Radio Variac Type 10B (Type M2) variable autotransformer in its TFX-5297 test board enclosure has been inspected and is in good used condition. It was pulled from a working environment where it was in active use. The blue front panel shows surface scuffing and paint wear consistent with lab use, and the gray enclosure has scattered paint chips and light surface oxidation on the sheet metal. The internal toroidal autotransformer core and wiper assembly are intact and visible through the open base. The front panel test points, banana jacks, rotary Vari-Set knobs, and indicator components all appear complete. A Burny M55302/4-03 mil-spec connector and wiring harnesses are included as shown. The CALIBRATION NOT REQUIRED label is affixed to the panel. Please view our photo set and contact us if you have any questions.
