Power Analyzer PA4000 Datasheet Applications Power Conversion Power Generation Inverters Motor Drives Electrical Propulsion UPS Frequency Converters Tektronix PA4000 Power Analyzers deliver highly accurate, multi-channel power, energy, and efficiency measurements. Precisely-matched inputs, unique Spiral ShuntTM technology, and advanced signal processing deliver high accuracy even with highly modulated waveforms and crest factors as high as 10. The versatile PA4000 offers comprehensive power measurements. Dual current shunts provide optimal resolution from microwatts to kilowatts. Harmonics analysis up to the 100th harmonic, and motor analysis with torque and speed inputs are included in the standard instrument. Every PA4000 comes with multiple PC interfaces, PC software, and USB flash drive support to help you collect and analyze data. Key features 1 to 4 Input Modules allows several configurations to match your application High measurement accuracy of 0.04% (basic voltage & current accuracy) for demanding test requirements Dual internal current shunts for each module maximize accuracy for high- and low-current measurements Unique Spiral ShuntTM design maintains stability over variations in current, temperature, etc. (patent applied for) Electric and Hybrid Vehicle High-Efficiency Lighting Consumer Electronics Standby Power Flexible voltage and current input choices to fit your application The PA4000 is the only instrument of its kind to feature both high- and lowrange internal current shunts in each input module. The 30-Amp shunt is perfect for many applications and can accept up to 200 A peak; but for measuring low-current devices the 1 A shunt provides increased resolution and accuracy for measurements down into the microamp range. For measuring currents over 30 Amps, a selection of matching external current transducers are available in several styles, including high-accuracy transducers up to 1000 A. The PA4000's voltage inputs can accept up to 1000 Vrms, 2000 Vpeak, continuous. Proprietary frequency detection algorithms ensure rock-solid frequency tracking even on noisy waveforms Application-specific test modes simplify instrument setup and reduce the likelihood of user error Easy data export to USB flash drive or remote PC software, for reporting and/or remote control Many standard features such as comm ports and harmonic analysis eliminate costly upgrade options PA4000 Rear Panel - Input Modules Datasheet Unique Spiral ShuntTM technology (patent applied for) The PA4000 employs an innovative Spiral Shunt design that ensures stable, linear response over a wide range of input current levels, ambient temperatures, crest factors, and other variables. This new design is superior to other shunt technologies and contributes to the instrument's reliable accuracy and repeatability over a wide range of signal conditions common in today's power conversion technologies. The spiral construction not only minimizes stray inductance (for optimum high frequency performance) but also provides for high overload capability and improved thermal stability. Application-Specific test modes Some applications require special instrument settings to ensure proper measurements. The PA4000 simplifies setup for these applications by automatically choosing instrument settings and parameters that are optimized for each type of measurement application, resulting in more reliable measurement results with less opportunity for user setup error. Selection of application-specific test modes. PWM motor drive mode PWM motor mode is designed to overcome the difficulties associated with making measurements on the complex waveforms commonly found on the motor drives. High frequency sampling is combined with digital filtering to reject the carrier frequency and extract the motor frequency while still using prefiltered data for power parameters Spiral Shunt for 30 A input Standby power mode Driven by consumer demand and energy efficiency regulations (such as ENERGY STAR), there is an ever-increasing need to measure power consumption of products while they are in standby mode. One of the most widely used standards for measurement is IEC 62301. Part of this standard requires the measurement of power over a prolonged period of time without missing any short duration power events. The PA4000 standby power mode provides continuous sampling of voltage and current to produce an accurate Watts measurement over the user specified period. Spiral Shunt for 1 A input 2 www.tektronix.com PA4000 Power Analyzer Ballast mode Standard communication ports Ballast mode synchronizes measurements for highly modulated electronic ballast waveforms. In modern electronic lighting ballasts, it is often difficult to make accurate measurements because the output signals are high frequency waveforms that are heavily modulated by the power frequency. Ballast mode provides a way of locking the measurement period to the power frequency. The PA4000 comes standard with USB, Ethernet, and RS-232 communication ports, plus a front-mounted USB port for data export to a flash drive. GPIB is available as a factory-installed option. Integrator mode Integrator mode is used to provide measurements for determining energy consumption (Watt-hours, Ampere-hours, etc.). In addition, for certain parameters, average values are also available. Standard harmonics analysis The PA4000 features harmonics analysis to the 100th harmonic as a standard feature. Harmonics, THD, and related measurements can all be analyzed simultaneously with other power parameters. Accurate measurement of harmonic amplitude, phase, and harmonic power are included, which are critical to the analysis of losses in rotating machinery.
