ACS71020 - Allegro

ACS71020 AC Power Monitoring

The Allegro ACS71020 power monitoring IC greatly simplifies the addition of power monitoring to many AC powered systems. The sensor may be powered from the same supply as the system’s MCU, eliminating the need for multiple power supplies and expensive digital isolation ICs. The device’s construction includes a copper conduction path that generates a magnetic.

Features

• Accurate power monitoring for AC applications
• UL certification for reinforced isolation up to 517 VRMS in a single package
• Accurate measurements of active, reactive, and apparent power, as well as power factor
• Separate RMS and instantaneous measurements for both voltage and current channels
• 0.85 mΩ primary conductor resistance for low power loss and high inrush current withstand capability
• Dedicated voltage zero crossing pin
• Overcurrent fault output pin
• Hall-effect-based current measurement with common- mode stray field rejection
• User-programmable undervoltage and overvoltage.
