>>Overview

 

N-8000 series digital display controller is an intelligent digital display controller with auto-tuning function developed by our company. This series of instrument adopts the advanced techniques and crafts of the single chip, SMT surface paste mounting, switch power supply, dual-channel PID auto-tuning algorithm, electromagnetism compatible design, etc.

 

>>Features 

Adopting large display screen, the insert depth of the instrument is 105 mm and the size of
surface panel meets the criterion of IEC.Adopting the forward-insert assemble structure manufactured by high elasticity, metal
shrapnel, replacing instrument is convenient.Adopt SMT technology, switch power supply, dual-channel PID auto-tuning algorithm,
electromagnetism compatible design with the combination of hardware and software. Acquire the title of "National Major-Product in year 2000" gloriously
