Shanghai Belling Multi-Circuit Calibration-Free Power Metering Chip BL0910

Description:

BL0910 is a multi-circuit, calibration-free power meter with built-in clock for up to 10-phase AC/DC energy measurement.

Measurement. It is suitable for 5G base station DC detection module, data center PDU, 5G base station macro unit multi-circuit meter, power distribution cabinet, multi-circuit fault detection and other applications.

The BL0910 is suitable for applications such as 5G base station DC detection module, data center PDU, 5G base station macro unit multi-circuit meter, power distribution cabinet, multi-circuit fault detection and so on. 

BL0910 integrates 11 channels of high-precision Sigma-Delta ADC, which can simultaneously measure 11 signals (current or voltage).  

The BL0910 is capable of measuring parameters such as current, RMS voltage, active power, active energy, etc. It can output a fast current effective value (for leakage monitoring, fault detection, etc.).

RMS value (for leakage monitoring, overcurrent protection and other fault detection), as well as temperature detection, waveform output and other functions, through the UART or high-speed SPI interface output data.

BL0910 can output data through UART or high-speed SPI interface, which can fully meet the needs of IOT big data acquisition. 

BL0910 can also obtain full wave, fundamental wave or DC RMS and power by selecting different filters for the input waveform.

power. 

The BL0910 is factory calibrated to <1% channel gain error. Without calibrating the whole unit, the external high precision sampling resistors can be used to minimize the overall measurement error.

The overall measurement error can be less than 2% without calibration. If high precision measurements are required (<0.3% error of the whole unit), the whole unit needs to be calibrated.

calibration is required if high precision measurement is required (<0.3% error).
