Key Features
- All-in-One Power Monitoring: Measures voltage, current, active/reactive/apparent power, and power factor from a single IC - eliminating the need for separate CT clamps and voltage transformers.
- Allegro ACS37800 IC: Industry-grade hall-effect power monitoring IC with on-chip DSP for true RMS calculations and high measurement accuracy.
- Galvanic Isolation: Safely monitor mains-level AC power with isolated current sensing - no direct electrical connection between high-voltage path and your microcontroller.
- Dual Digital Interface: Communicate via SPI or I2C, giving you flexibility to integrate with virtually any microcontroller platform.
- On-Chip EEPROM: Store calibration data and configuration settings directly on the IC for persistent, reliable operation across power cycles.
- Overcurrent & Zero-Crossing Detection: Built-in fault protection and zero-crossing output enable smart load switching and safety shutdown routines.
- AC & DC Compatible: Monitor both AC mains power and DC bus power, making it versatile for solar inverters, battery systems, and appliance metering.
- Compact Breakout Design: Breadboard-friendly header pins and clear silkscreen labelling for rapid prototyping and easy PCB integration.
