Smart Multichannel Vector Power Analyzer

The SMVect-PA is an Industrial grade, high accuracy, Electrical 3 Phase Power Analyzer and Multichannel Smart Meter that provides fundamental, harmonic and total active, reactive and apparent power and energy on each phase and of the overall system. It also measures Power Factor, Frequency and RMS values of Voltages and Currents. The PA incorporates line voltage period measurement, and angles between phase voltages and currents.

It incorporates power quality measurements such as short duration high/low voltage and current events etc. Under special configuration it can provide raw sampled waveforms of Voltages and currents of all 3 phases and neutral current as well.

As a Smart Power Meter, it is compatible in measurements in 3-phase, 3 or 4 wire (Delta or Wye) and other 3-phase services.

The SMVect-PA is built around a Mixed Signal, 32bit, Floating Point Digital Signal Controller, and ASICs, carrying out strict real time precision measurements and signal processing. The system provides multiple additional channels of current measurements, thus creating vectors of Active, Reactive and Apparent, Power and Energy per channel. This precisely measures power and energy distribution over multiple channels and thus stock of quantities on a per channel basis. The same input analog channels can also be used for diverse industrial analog sensors and a mix/combination of sensor inputs. This enables realization of complex power/energy measurement systems.

The analog interfaces are DC Current Transformers (DC-CT) Compatible. With Isolated precision DC Voltage Measurement Addon, sampled at high rate in real time, the PA can also measure bidirectional DC Power, Energy, Voltage and Current, their main components and the harmonic content.

Additionally precise isolated digital inputs for counting, pulse width and pulse/sec measurements provided industrial measurements. Additional 4-20ma compatible interfaces are also provided for sensor measurements.

Communication interfaces include isolated RS 485, isolated CAN, isolated USB2 Slave and optional Ethernet. I2C and SPI connectors are available for additional compatible addon boards for capability extension.
