Energy measurement products

The foundation for more accurate measurement

Bring together the sensing, calculation, calibration, and monitoring capabilities your power application demands.

High Dynamic Range Measurement
Measure accurately across a 4000:1 dynamic range, maintaining dependable performance from low-level signals through higher-load conditions.
Scalable Measurement Channels
Choose the channel count that fits your design, with two, three, or four 24-bit ADCs for flexible voltage and current measurement.
Flexible Current Sensor Support
Connect shunt resistors, current transformers, or Rogowski coils to match your sensing architecture and simplify system integration.

On-Chip Power Calculations
Calculate RMS voltage and current, active, reactive, and apparent power, power factor, line frequency, and instantaneous values on-chip.
Fast On-Chip Calibration
Speed development with fast on-chip calibration that helps you tune system accuracy across sensors and operating conditions.
Power-Quality and Fault Monitoring
Detect overcurrent, voltage sag, and voltage swell to help monitor power conditions across demanding measurement applications.
