Power transformers convert power-level voltages from one level or phase configuration to another.

Transformer Test Equipment consists of specialized test modules or systems used to test and/or monitor electrical and mechanical parameters of transformers and other related devices

Toroidal transformers typically consist of copper wire wrapped around a cylindrical core.

Linear variable differential transformer (LVDT) and rotary variable differential transformer (RVDT) signal conditioners are devices that translate the linear or rotary movement of a ferromagnetic armature into an AC voltage that is proportional to the armature position

Power quality analyzers measure and monitor electrical power parameters to avoid disturbances, track steady-state variations, and ensure the reliability of power distribution systems

Voltage converters and voltage inverters accept voltage input and provide a scaled voltage output.

Audio analyzers measure the noise and audio spectrum of output from an amplifier or a stereo.
