Voltage and frequency converter » EAC-F-1 & EAC-F-3
On the output side, the frequency converters are available in 1-phase, 3-phase or switchable from 1-phase to 3-phase operation and supply a pure sinewave voltage. Frequency converters are used to supply loads that require a different frequency than the available grid supplies, e.g. 400Hz at a voltage of 120/208V. The converters (EAC-F) are constructed with a power rectifier and an inverter. The power rectifier is designed for the grid supply and the inverter provides the required output frequency and voltage 1- or 3-phase.
