BL0921 Datasheet Single Phase Energy Meter

Manufacturer: BELLING

Overview: BL0921 Single Phase Energy Meter IC with Integrated Oscillator.

Datasheet Details

The BL0921 is a low cost, high accuracy, high stability, simple peripheral circuit electrical energy meter IC.

The meter based on the BL0921 is intended for using in single-phase, two-wire distribution systems.

It can exactly measure the real power in the positive orientation and negative orientation and calculate the energy in the same orientation.

High accuracy, less than 0.1% error over a dynamic range of 500: 1 On-chip oscillator as clock source Exactly measure the real power in the positive orientation and negative orientation, calculate the energy in the same orientation Two current monitors continuously monitor the phase and neutral currents in two-wire distribution systems. Uses the larger of two currents to bill, even during a Fault condition A PGA in the current channel allows using small value shunt and burden resistance The low.
