The meter based on the BL6503E is intended for using in single-phase, two-wire distribution systems. The BL6503E adopts the oversample technology and digital signal processing technology. It can exactly measure the real power in the positive orientation and negative orientation and calculate the energy in the same orientation. Moreover, BL6503E supplies the negative orientation indication on Pin20 (REVP). Therefore, the meter using the BL6503E has great capability to avoid fault condition. The BL6503E supplies average real power information on the low frequency outputs F1 (Pin23) and F2 (Pin24). These logic outputs may be used to directly drive an electromechanical counter and twophase stepper motors. The CF (Pin22) logic output gives instantaneous real power information. This output is intended to be used for calibration purposes or interface to an MCU. The BL6503E adopts the...
