The BL0930E is a low cost, high accuracy, high stability, simple peripheral circuit electrical energy meter IC. The meter based on the BL0930E is intended for using in single-phase, two-wire distribution systems.
Features
- High accuracy, less than 0.1% error over a dynamic range of 3000 : 1
- Exactly measure the real power in the positive orientation and negative orientation, calculate the energy in the same orientation
- A PGA in the current channel allows using small value shunt and burden resistance
- The low frequency outputs F1 and F2 can directly drive electromechanical counters and two phase stepper motors and the high frequency output CF, supplies instantaneous real power, is intended for calibration and communications
- The logic outputs REVP can be used to indicate a potential orientation
- Low static power (typical value of 15mW). The technology of SLiM (Smart–Low–current– Management ) is used.
- On-Chip power supply detector
- On-Chip anti-creep protection
- On-Chip oscillator
- On-Chip voltage reference of 2.42V +- 8% (typical temperature coefficient of 30ppm ), with external overdrive capability
- Single 5V supply
