HS-50 Frequency Changers
(KGS products can only be shipped to U.S. address only.)
(DAI Part# HS50)
The HS and HB series are lightweight frequency changers. These models utilize the latest state of the art, solid state circuitry to convert a 115/200VAC, three-phase, 400 Hz input to either a 115VAC, 60 Hz or 230VAC, 50 Hz sine wave output.

Design features include a crystal controlled oscillator for output frequency stability and a pulse-width-modulated square to sine wave power conversion scheme for reliable and quiet operation. The model HS and HB series frequency changers are designed to operate television sets, video cassette recorders (VCR), stereo entertainment systems, computers, coffee makers, microwave ovens and EMS equipment.
