Application of Embedded Industrial Android All-in-One Devices in Three-phase Programmable Power Sources

Industry Demand

The fundamental requirement for the power industry towards three-phase programmable power sources is the precise and effective detection, adjustment, and modification of voltage, current, phase, and power. Stability in handling input and output currents, coupled with software calibration, ensures high-precision output of AC/DC voltage, current, phase, and power, thereby addressing market issues such as "virtual power" metering.

Solution Objective

In response to the input and output challenges faced by three-phase programmable power sources regarding electrical energy, Stark introduces a tailored solution. It offers automatic or manual verification of electrical equipment while saving multiple experimental scenarios. It generates complete sine wave signals with precise control over distortion and enables independent regulation of current, voltage, and phase in any phase for actual AC power generation during performance tests or metering. Equipped with various protective functions like current limiting, overheat, voltage short-circuit, and current open-circuit protection, it ensures high stability, fast, and accurate detection and compensation.

System Composition

The three-phase programmable power source is a high-precision testing instrument that integrates electricity meter verification, electrical parameter testing, and detection of power quality issues like waveform distortion, voltage fluctuations, and three-phase imbalance in power grids. Primarily used for testing and verification of power electrical digital meters, electrical sensors, transducers, and distribution automation terminals, it boasts an intelligent host connected to a computer for operation and a large LCD display.
