HT Instruments PQA 820S
Data logger for power & network analysis up to 1000AC
Technically like PQA820, but without current transformer (see accessories)
- 4 channels for current 0.1A to 1000A AC TRMS
- Channels for voltage 10V to 460V AC TRMS
- Apparent, active and reactive power measurement
- Apparent, active and reactive energy measurement
- Measurement of cos and power factor (PF)
- Measurement of frequency
- Calculation of THD for voltage and current
Thanks to the innovative concept, the PQA820 can be connected to smartphones, tablets and PDAs (iOS and / or Android), providing the user with precise real-time information on all consumption values of the system to be measured. All electrical parameters are displayed in numerical or graphical mode including waveforms and histograms.
The large integrated memory allows for a recording period of over 30 days with e.g. 383 selected measuring parameters and a measuring interval of 10min. The PQA820 saves all 383 parameters as standard and thus avoids possible setting errors. Only the mains form (single-phase, 3-phase with N or 3-phase without N) must be selected by the user.
The PQA820 is powered by an internal Li-ion battery and an integrated mains supply via the L-N or L-L connector. The Wi-Fi and USB interfaces provide easy connection to smartphones, tablets, PDAs and PCs for instrument configuration, starting and stopping measurements, downloading data and online analysis.
The IP65-rated PQA820 (waterproof) enables outdoor use in harsh environments.
