■ Outline

■ Characteristics

• It has great inverter efficiency with the high efficiency inverter method.
  
• Low distortion: By using the multi-inverter method this device has a lower waveform signal-versus-noise ratio than the conventional PWM inverter method.
  
• High stability: The output stability is high for variations in input-voltage and load.
  
• The input and output are of a complete isolation type.
  
• Since it uses a semiconductor for the variable frequency and voltage, the response speed is much faster than the conventional Slidac method and has no damping (Slidac method: about 1 second, semiconductor method: 0.1 second or below).
  

■ Application

* For the alternating rotator test or exclusive power supply facility * For the inspection of environmental test facility
* For the reliability-test and inspection of electrical devices in exporting or importing * For the monitor inspection
* For the inspection of power transformer * Lab power source
* For the inspection of lighting devices (electric or electronic stabilizer) * Display source and inspection (PDP, LCD, and etc.)
