HT Instruments PQA820 Power analyzer, power analyzer

Three-phase data logger for network and power analysis. The PQA820 is a power quality analyzer designed for easy and comprehensive analysis of the key parameters of the electrical system, including power consumption and energy usage. Measurements are taken via 4 current transformers and 4 voltage inputs.

Online analysis. Thanks to its innovative design, the PQA820 can be connected to smartphones, tablets, and PDAs (iOS and/or Android), allowing users to receive precise real-time information on all consumption values of the system being measured. All electrical parameters are displayed in both numerical and graphical modes, including waveforms and histograms.

Storage. The large built-in memory allows for a recording duration of over 30 days with, for example, 383 selected measurement parameters and a measurement interval of 10 minutes. The PQA820 automatically stores all 383 parameters, thus avoiding potential configuration errors. Only the network type (single-phase, 3-phase with N, or 3-phase without N) needs to be selected by the user.

Interfaces. The PQA820 is powered by an internal lithium-ion battery and an integrated power supply via the L-N or L-L connection. The Wi-Fi and USB interfaces provide easy connectivity to smartphones, tablets, PDAs, and PCs for device configuration, starting and stopping measurements, downloading data, and online analysis.

Housing. The PQA820, classified with an IP65 protection rating (waterproof), is suitable for outdoor use in harsh environmental conditions.
