Precision Power Testing: ZX1030 Single-Phase Programmable Source
Introduction
For technicians and engineers working in electrical metrology and calibration, the ability to generate highly stable and accurate AC signals is essential. The ZX1030 Precise Single-Phase Programmable Testing Source represents a significant advancement in portable precision power sources. It combines programmability, metrology-grade performance, and robust construction, making it an ideal tool for calibrating a wide range of electrical instruments.
Key Features and Technological Advantages
At its core, the ZX1030 utilizes a combination of FPGA, high-speed high-resolution D/A conversion, and Direct Digital Synthesis (DDS) technology. This architecture allows for precise independent control of output voltage, current, frequency, and phase. Unlike many conventional sources that rely on analog circuitry, the digital PID control and analog closed-loop feedback ensure the output automatically tracks the set parameters with exceptional stability over extended periods.
A standout feature is its integrated high-accuracy standards for voltage, current, power, and energy. This effectively combines the functions of a standard power source, an indicating meter, and an energy meter into a single, portable unit. Its high-power operational amplifier ensures high-fidelity output signals with strong anti-interference and load stability.
Performance Analysis: Precision and Flexibility
The technical specifications of the ZX1030 place it at a high performance level:
Voltage Output: 0-720V with multiple rated ranges (25V-600V), adjustable from 0-120% with a resolution of 0.005%. Its accuracy is ≤±0.06%(Rd) ±0.04% (fs) for 0.1 class.
Current Output: 0-24A with standard ranges (0.1A-20A), offering the same high accuracy and a resolution of 0.005%.
Frequency & Phase: Output frequency ranges from 45Hz to 65Hz with a resolution of 0.001Hz and an error of just 0.01Hz. Phase adjustment from 0° to 359.99° with an error of 0.1°.
Harmonic Synthesis: A valuable feature for testing advanced meters, it can add 2nd to 32nd harmonics with amplitude up to 20% of the fundamental.
Power & Energy Accuracy: Power output accuracy matches that of voltage/current (0.1 class). Energy (watt-hour) integration error is an impressive 0.1% or 0.05% of full scale.
Comparative Perspective
Compared to older generation test sets or general-purpose AC sources, the ZX1030 offers distinct advantages:
Integrated Calibration Standard: Many traditional setups require a separate precision calibrator, a standard meter, and a power amplifier. The ZX1030 integrates all these into one device, simplifying the workflow and reducing potential error sources.
Digital Control vs. Analog: Traditional analog sources can drift with temperature and time. The digital PID control in the ZX1030 ensures superior long-term stability and automatic compensation for load variations.
Portability: Housed in a protective aluminum alloy case (18kg), it is significantly more portable than rack-mounted systems of comparable capability, making it perfect for both lab and field use.
Functionality: The addition of harmonic synthesis is a feature often found only in more specialized and expensive equipment, giving the ZX1030 greater versatility for testing modern, sophisticated devices.
Application and Data Management
The device is designed for calibrating various instruments, including power meters, energy meters (kWh), transformers, and transducers. Its PC connectivity allows for the automation of calibration procedures and centralized management of test data, enhancing productivity and ensuring traceability.
Conclusion
The ZX1030 Precise Single-Phase Programmable Testing Source is a powerful, accurate, and remarkably versatile instrument. For technicians seeking a reliable, all-in-one solution that outperforms traditional test equipment in accuracy, stability, and functionality, the ZX1030 represents an excellent choice for high-precision electrical testing and calibration tasks.
