Ferro - Resonant Type

Ferro - Resonant Type



  •  With very good voltage stabilization, nearly 0% of error operationprobability. (Because there is no control circuit inside, only with two individual components comprising)
  •  Output overload or short circuit will automatically limit the current. (One-hour will not result in any damage to the product.)
  •  Output waveform will not be influenced by the input waveform. (When the input waveform is seriously terrible, it will only influence its efficiency to decrease a little, but the output waveform will still be sinusoidal wave.)
  •  Input and output are completely isolative. With good resistance to static electricity, ground lightning, noise and high voltage pulse (more than 60db).
  •  Input voltage can apply neither 110V nor 220V, and output voltage can simultaneously apply 110V and 220V.
  •  With good reactivity to SURGE: when the input voltage suddenly increases to 170V, the output voltage will remain 110V± 2.5%.
  •  With good reactivity to SAG: when the input voltage suddenly decreases to 65V and the load is less than 60%, the output voltage will remain 110V± 2.5%.
