2. Product introduction

PIS is multi-function integrated power supply,is able to realize power management and control.PIS-O outdoor type is of following functions:oil engine monitor,ATS power supply switch,choose 2 from 3 phase,non-contact stablizer,ACDB distribution unit,SPD protection,GSM control and alarm,fire alarm.PIS control adopt multi-processor,which are dependently and in connection.128*64 LCD screen is able to display kinds of PIS parameter,it is highly integrated and light. temp_PIS_2

4. Working principle

PIS is 3 way power supply integrated management system( 1 way commercial electricity,2 ways oil engine).If commercial electricity is normal,ATS could choose commericial electricity firstly.phase selector could choose 2 qualified power suply,then provide power to load after AVR stablizing.Even there is phase lacking,it could also make sure the output of AVR.If commerical electricity is cut off,PIS could test voltage of storage battery.
Oil engine monitor system start up oil engine 1and ATS choose running oil engine to supply power if storage battery is unable to meet requirements of load.Then oil engine 1 stop running as per regulated time,oil engine 2 begine to run.If one oil engine goes bad,it will stop running,and the other one begin to work.Two engines work by turns.Once commerical electricity becomes normal,oil engines could switch to commercial electricity.
PIS Protection: anti-lighting,SPD protect,overvoltage protect,undervoltage protect,overload protect,short circuit protect,high frequency protect,low oil pressure protect,low oil position protect,low speed protect,fire protect,guardance protect,and temperature protect.
GSM alarm function could inform manager by GSM message if there is fault,administer could act according to GSM.
