1 Overview 
 SPA-96BDE electronic energy meter is used in the electricity sector, factories, businesses, commerce, agriculture, power, lighting equipment, active energy measurement. Used to measure the frequency of 50Hz AC three-phase active energy and power LCD, intuitive readings for meter reading, the instrument can be extended to the RS485 communication function, advanced and reliable measurement tools for three-phase power measurement. 
 Measurement module used in the SPA-96BDE electronic energy meter can accurately measure the three-phase positive and negative bi-directional active energy. The electronic energy meter with accurate measurement, stable and reliable, has good resistance to electromagnetic disturbance, low power, high accuracy, wide range, long life characteristics. 
 2.SPA-96BDE electronic energy meter works 
 This power meter uses three-phase power supply, and can work in any single-phase power supply case. 
 Work when the power meter, voltage, current through the sampling circuit were sampled and sent to large-scale ASIC buffer amplifier, and then converted into digital signals by the 16-bit A / D converter, convert and electricity by the digital multipliers operator, size is proportional to the pulse driver counter indicator of energy accumulation and the driving pulse and output pulses for measuring.
