4. Functionality
The MDV5105 operates as a precision AC-to-DC converter that measures the true RMS value of an AC input signal and outputs a corresponding DC voltage. Unlike average-responding converters, the True RMS measurement capability ensures accurate readings even for non-sinusoidal waveforms, including those with harmonic distortion or irregular shapes.
Working Principle:
1. The input AC signal (±20 V) is fed into an RMS-to-DC conversion circuit.
2. The circuit computes the square of the instantaneous voltage, averages it over time, and then takes the square root to determine the RMS value.
3. The resulting RMS voltage is scaled linearly to produce a 0–5 V DC output proportional to the input amplitude.
4. The output can be directly connected to analog inputs of PLCs, controllers, or monitoring systems.
Use Cases and Applications:
- Industrial process monitoring and control systems
- Power quality analysis and instrumentation
- Measurement of AC voltage signals from sensors or transducers
