Import Energy Analyzer — Buy in Bulk from Supplier in China

The PZ96L-3EH energy analyzer from Shanghai Acrel Electric Co., Ltd is a multifunction device designed to measure electrical parameters in three-phase networks, including voltage, current, active and reactive power, energy import/export, and harmonic content up to the 31st order. It operates on AC/DC 85 - 270V supply, supports 1P2W, 3P3W, and 3P4W configurations, and has a measurement accuracy of 0.5 class for most parameters and 1 class for reactive energy. The unit features a liquid crystal display showing waveforms, bar graphs of harmonics, and vector diagrams for voltage and current.

The device complies with EN 61326:2006 and EN 61010-1:2001, and meets RoHS Directive 2002/95/EC. It includes isolation ratings of AC 2kV/1min between power, current, and voltage inputs, and AC 1.5kV/1min between logic inputs and RS485. Typical industry standards for such analyzers include IEC 61000-4-2 to -4-5 for electromagnetic compatibility, all of which this model meets at Level 3. The input range for voltage is 100V or 400V nominal, with overload tolerance up to 600V continuous and 1000V for 30 seconds; current inputs are rated for 1A or 5A, with overload tolerance up to 6A continuous and 50A for 10 seconds.

This analyzer is used by industrial facility managers, energy auditors, and electrical engineers to monitor power quality, detect harmonic distortion, and assess transformer loading via K-factor and THFF metrics. Buyers typically integrate it into switchgear panels or control rooms for real-time diagnostics. It supports communication via RS485 (Modbus-RTU) and an optical interface for firmware updates. Packaging is standard industrial-grade, and the unit weighs 1.5kg with dimensions of 96x96x84mm. Trade terms such as lead time and packaging options must be confirmed directly with the supplier.
