XITRON 2503AH Sitron Three-Phase Power Analyzer (Ballast Test)

The 2503AH series provides state-of-the-art power analysis capabilities for applications such as lighting, power conversion, and equipment testing and development. Each analyzer can measure power, voltage, current, and frequencies up to 500kHz at the highest accuracy. Measurement parameters include voltage, current, watts, power factor, crest factor, K factor, third harmonic distortion, harmonics, phase, VA, VAR, W. Hr, Triplens, impedance, inrush current peak, efficiency loss, and more.
Xitron power analyzers have established a practical standard for production testing in many industries. Independent channel control and high-speed measurement make the 2503 the instrument of choice for three-phase power analysis.
The 2503AH-1CH / 2CH provides a low-cost, high-performance test solution for single-phase applications such as power supply and equipment testing. Standalone IEC-1000-3 testing is also a unique feature of Xitron.

Motor Testing
The 2503AH provides multiple real-time measurements, such as single-phase, two-phase, and three-phase power, inrush current, power factor, harmonics, and limit testing. High-speed sampling and FFT technology deliver excellent test results for frequencies up to 500KHz. This technology is especially suitable for variable-speed disk drives. Input voltage can be as high as 3000V peak, and the built-in Hall-effect CT supports up to 40ARMS. Synchronous sampling analog input channels allow direct efficiency testing. Users can configure up to 50 parameters for display, providing simple production setup. Multiple test configurations can also be stored and accessed, and computer remote control is possible via RS-232 or IEEE-488 interfaces.

Lighting Applications
Xitron instruments have set a new standard for speed and accuracy in electronic ballast testing. The high-speed FFT processor can reduce ballast test time by up to 75%. Test parameters include efficiency, power factor, distortion, and individual harmonic content. The 2503AH series fully supports IEC-555 compliance testing and is widely adopted by advanced test laboratories, test system manufacturers, and the world's three largest lighting product manufacturers.
Uninterruptible Power Supply / Power Supply Testing
The 2503AH series enables power supply testing, measuring efficiency, power factor, distortion, harmonics, spectral content, and inrush current. It acquires test results faster than other power analyzers on the market and with higher accuracy. The 3000V and 500A peak load capability protects the instrument from damage caused by transients during testing.

Equipment Testing
Test power loss, peak load, and power factor, quickly perform production testing using stored settings, and print test results in user-defined formats on any printer. For quality programs based on statistical process control, users can implement automated testing using an inexpensive PC controller, and the test system will collect the required statistical data.

Application-Specific Configurations
The 2503AH power analyzer comes preconfigured with the procedures required for electronic ballast testing, several three-phase setups, and motor testing. Users can configure the 2503AH as three independent analyzers or as one state-of-the-art three-phase analyzer. In electronic ballast testing, when one channel is set to measure line input data, the other two channels measure high-frequency signals, which directly yields efficiency measurements. To ensure maximum flexibility, users can store up to 65,000 application-specific configurations in the instrument. High-accuracy calibration with total error below 0.05% is also suitable for most work requirements, such as wattmeter testing.

Harmonic and Spectrum Analysis
In terms of signal analysis capability, the greatest feature of the 2503AH series is speed and precision. Each channel is independently synchronized and has two digital signal processor chips. While one chip performs all synchronization and sampling operations, the other performs a fast Fourier transform on the sampled current and voltage signals with true 18-bit resolution. Current and voltage have separate but fully synchronized A/D waveform capture sections. In the dual digital signal processor architecture per channel, the result is ultra-fast harmonic analysis. Harmonic analysis can be produced in as little as 10 milliseconds, or measurements can be integrated over more than a day. Users can set any measurement interval, perform synchronous harmonic averaging, and conduct full-spectrum analysis to detect non-harmonic signal content. The system's main microprocessor controls all display, data storage, and I/O functions, allowing each channel to perform analysis at the highest speed.

IEC1000-3 Compliance Testing
High resolution and fast processing enable Xitron power analyzers to perform complete IEC1000-3 testing. Users can select a simple pass/fail display or record the individual content of all harmonics according to the IEC-3-2 standard. The 2503AH meets all detailed requirements of IEC1000-3, including voltage drops and fluctuations across the instrument with a maximum 0.15 peak, and the gapless/non-overlapping 16-cycle requirement for harmonic measurement. IEC1000-3-3 flicker analysis is a powerful feature; while testing is in progress, it can display system structures such as Ut, Pst, Plt, dt, and dmax, enabling Xitron power analyzers to perform half-cycle-by-half-cycle measurements and Laplace transforms.

Data Display and Interface Flexibility
The 2503AH series allows users to configure the desired display and copy ranges. Users can define individual ranges, scroll up and down the display, or print the range to a standard PC-compatible printer. Other copy options include harmonics and their fundamental parameters. Simple computer control is available via IEEE-488 or RS-232 ports. Because all channels perform inherent processing and the main processor manages I/O, the power analyzer can provide non-parallel interface speed. 12 analog and 16 digital outputs can be configured to track and alarm specific parameter ranges.
