PL3223

FXXC Function Feature ® IC FOR MULTI-FUNCTION THREE-PHASE ELECTRIC AL ENERGY METERS PL3223 voltage detecting, it has interrupt output. Current channel embeds Programmable Gain Amplifier (PGA). Support digital phase correction and linear compensation of small current segment Built-in digital temperature sensor, support segment compensation of temperature Constant of electrical energy meter and starting current can be calibrated by digit. SPI interface, which facilitate control of external microprocessor. AD waveform data of real time voltage and current of all phases Temperature standard of industry class, QFP44 pin packaging. It is compatible with both three-phase three-wire and three-phase four-wire. High accuracy electrical energy measurement. It matches IEC678/6103¡¢ GB/T 1721 and IEC1268¡¢ GB/T 17882. The error of active electrical energy measurement is less than 0.1% in the dynamic area 1000:1. The error of reactive electrical energy measurement is less than 0.2% in the dynamic area 1000:1. It can accurately measure the reactive electrical energy of up to 21st harmonic. Active/reactive calibration meter pulse output Measuring instantaneous active/reactive, line voltage frequency and RMS value of voltage/current. Simultaneously supply split phase and mergence phase active/reactive and symbolic indication It can select energy accumulation mode of merge nce phase (algebra summation/absolute value summation) Two stepping motor drive output, which can simultaneously outpu...
