  • Voltage output waveform (Max Luminance)

  • Current output waveform(Max Luminance)

  • NOTES:
  • A.Current of the lamp must use a high frequency current meter,There have a four amperes fuse in the inverter
  • B. Do not attach a conducting tape to lamp connecting wire, if the lamp wire attach to conductive tape, TFT-LCD module have a low luminance and the inverter has abnormal action because leakage current occurs between lamp wire and conducting tape. If the display arrangement is less friendly such as the asymmetrical wiring forces unequal losses and the lamps receive imbalanced current. Even with identical lamps, illumination may not be balance.
  • C. For Safety Issue, please keep 4.0mm at least from the metal parts of the system to the inverter. Or put a suitable insulator between the inverter and the metal parts to avoid the situation of breakdown or arcing etc.
  • D. Don’t twist , deform , drop or knock the inverter during assembly
  • E. Guarantee to offer ESD shield bag to protect the product from electrostatic or magnetic interference during delivery. Due to the inverter is usually designed without the enclosure. please take care about ESD at anytime .
  • F. The products are not intended for use in systems in which failures of product could result in personal injury
