4. Functionality
The VMDV50011 functions as a precision AC-to-DC converter that measures the true RMS value of an AC input signal and outputs a proportional DC voltage. Unlike average-responding converters, it accurately represents the effective power of the signal, regardless of waveform distortion or harmonic content.
Operating Principle:
1. The input AC signal (±10 mV) is fed into the RMS conversion circuitry.
2. The internal analog computation circuit squares the instantaneous input voltage, averages it over time, and then takes the square root to derive the RMS value.
3. The resulting RMS value is converted into a proportional DC voltage output (0–5 V).
4. The output can be directly connected to analog input channels of PLCs, controllers, or monitoring systems.
Use Cases and Applications:
- Industrial process monitoring and control systems
- Power quality measurement and instrumentation
- Sensor signal conditioning for vibration, current, or voltage sensors
- Laboratory test benches and calibration setups
