Product overview

ANPA4000(F) Series is a multi-channel, high-precision power analyzer that supports simultaneous measurement on 1 to 8 channels and can be flexibly configured for single-phase, three-phase, and other modes.

It features FPGA+ARM dual-core processing with 16‑bit high‑speed AD converters, achieving a basic accuracy of 0.03% of reading + 0.05% of range.

The instrument offers a wide frequency band (DC, 0.5 Hz to 1 MHz), multi‑channel harmonic analysis (up to the 500th order), motor measurement, efficiency calculation, energy accumulation, and other comprehensive functions. Standard current input is 30 A, with optional 5 A and external sensor inputs available.

It provides a full touchscreen experience and supports custom data storage and export. The series is widely used in photovoltaic inverters, electric vehicles, charging stations, motor test benches, and switching power supplies.
