Features

• Integrated Oscillator: Eliminates the need for an external crystal, simplifying design and reducing overall cost.
• High Accuracy: Provides an active energy measurement accuracy of 0.1% across a dynamic range of 500:1.
• Low Power Consumption: Efficient power usage for energy-efficient designs.
• Digital Calibration: Supports digital calibration of the meter, removing the need for manual adjustments.
• Direct Drive for Mechanical Counters: Capable of directly driving electromechanical counters and 2-phase stepper motors.
• Current Sensor Compatibility: Works with both shunt resistors and current transformers (CT) for flexible current measurement.
• Low Component Count: Requires minimal external components, reducing PCB size and simplifying design.
• Frequency Output: Pulse output frequency is proportional to the active power, making it simple to interface with microcontrollers or other systems.
