Audio transformers are involved in the transmission of voice or sound signals. They often require wide frequency bandwidth with low distortion and noise suppression.
Electronics assembly service companies based on providing contract design, manufacturing, and related product support services on behalf of electronics OEMs.
Instrument transformers are used to step-down current or voltage to measurable values. They provide standardized, useable levels of current or voltage in a variety of power monitoring and measurement applications.
Voltage transformers and potential transformers are used to measure voltage in electric circuits. Their main role is to condition (step down) the voltage to be measured to levels suitable for the measuring instrument.
