FunctionalCharacteristics

Intelligent measuring and control systemThe sampling system of current and voltage adopts 32-bitbuilt-in MCU made by Corex-M4, able to collect the signalsquickly, it can realize the high accuracy of measuring three-phase current,voltages,active power,reactive power,transparent power and etc system parameters, calculatingand analysis of harmonic waves

Human and machine exchange systemDisplaying monitor adopts LCD panel,Chinese menu,display the inner temperature,current,voltage andharmonic parameters at real time, push keys to seek theparameters and running status,also able to set overvoltage, under-voltage,under-current, over-temperature.over/under compensation data,can be saved in case ofpower failure.

eIntelligent connecting with systemRs485 comm port, buit-in MODBUS-RTU protocol, able torealize remotely monitoring and controlling. When severalproducts are connected with system in parallel, they willautomatically produce one master machine,the othersbecome the slave machines,forming areactive powercompensation system; if one of machine is out of service itdoes notinfluence on others operating,if the mastermachine exit the working,the system will auto produce anew master machine, highly intelligent operation.eIntelligent switching systemReally switching through zero current, auxiliary transistorcircuit is not needed,this system adopts the independentCPU to control the switching operation at passing zero,switching at zero,no surging current,no arcing,fastresponse,improve the reliability and service life of theequipment.

Power capacitorsCooperated with high performance power capacitors, goodradiation, small size, long service life, consequently it canensure the complete-set equipment with high safety andreliability
