Provide a high quality, stable power that static converters cannot.
These converters work effectively when the power of a different frequency than that offered by the commercial power supply is required for testing. (Example: When a 50-Hz power supply is needed in a 60-Hz region, or vice-versa)
These rotary converters provide a quality power supply with minimal waveform distortion, something not obtainable with static converters.
In addition to fixed frequency models, variable frequency output models are also available.
