BL6522B Belling three-phase metering chip smart meter IC

It is a high-precision three-phase multi-function electronic energy metering chip, suitable for three-phase, three-wire and four-wire multi-function electric energy meter applications, with extremely high cost performance.
It integrates high-precision, reference voltage circuitry. Able to measure the total (fundamental and harmonic) active power and energy, reactive power and energy, apparent power and energy of each phase and the combined phase of the three phases, as well as the fundamental active power and energy, reactive power and energy and each phase Parameters such as current, voltage effective value, power factor, etc. have current flow monitoring, current and voltage peak monitoring, zero-crossing monitoring and other power quality management, which can fully meet the needs of three-phase multi-function energy meters.
, integrates an interface to facilitate the transfer of measurement parameters and calibration meters to the outside.
, integrated on-chip temperature sensor, the accuracy can reach ℃
, supports input gain adjustment in the full digital domain, active phase can be calibrated (adjustable gain adjustment of each channel, active power, reactive power, apparent power calibration, Effective value calibration, etc.
, can be directly output in the form of pulses, (can also be configured as) signals, directly connected to the standard meter for active and reactive power (or apparent power) error correction.
, It has a low-power battery mode, which can be powered by the battery in the case of total loss of voltage, and ensures continuous accumulation of energy.
It uses data flow calculation method internally to process various signals, and has good performance under external interference. Reliability. The internal voltage monitoring circuit can ensure normal operation when powering on and off.
