4. Functionality
The MPVA200 operates as a True RMS power measurement device for AC systems. It continuously samples the voltage and current of the connected load, computes the instantaneous power, and derives the True RMS value of apparent power (in VA). The internal signal conditioning circuitry converts this measurement into a proportional DC voltage output (0–5 V).

Working Principle:
1. The module receives AC voltage and current inputs from the monitored circuit.
2. Internal RMS conversion circuitry calculates the real-time power value.
3. The measured value is scaled linearly to a 0–5 V DC output signal.
4. The galvanic isolation barrier ensures that the output signal is electrically separated from the high-voltage measurement side.

Use Cases and Applications:
- Monitoring of AC power consumption in industrial machines and equipment.
- Integration into energy management systems for load analysis.
- Laboratory testing and calibration setups requiring accurate power measurement.
- Building automation systems for monitoring distributed loads.
- Educational and research applications for demonstrating power measurement principles.
- OEM integration into control panels or test benches.

Compatibility:
- Compatible with standard analog input modules (0–5 V range) of PLCs, SCADA systems, and data loggers.
- Can interface with analog-to-digital converters for digital monitoring.
- Suitable for both single-phase AC systems and low-power test circuits.
