ZW8233C Power Monitoring InstrumentDetailed product description：

ZW8233C power monitoring instrument is an intelligent comprehensive instrument that uses microcontroller technology to directly sample, analyze, and process three-phase AC signals. It has many advantages such as complete functionality, economic practicality, high reliability, and strong anti-interference ability. It can replace various conventional instruments such as transmitters, pointer instruments, frequency meters, power factor meters, etc.

ZW8233C power monitoring instrument can measure parameters such as three-phase voltage, three-phase current, three-phase power, total power, power factor, frequency, harmonics, unbalance, and cumulative electrical energy. It also has functions such as waveform display and waveform recording.

Characteristics of ZW8233C Power Monitoring Instrument:
1. The measured signal value is the true effective value;
The 2.320x240 large screen LCD display window allows for simultaneous observation of multiple parameters. The button operation is simple and practical;
3. The same applies to signals with waveform distortion;
4. One instrument can measure multiple parameters;
5. Easy to connect with computers and achieve intelligence;

Purpose:
The ZW8233C power monitoring instrument measures AC signals at 45-65Hz and is mainly used for measuring three-phase power frequency signals. It can be measured using wiring methods such as three-phase four wire, three-phase three wire, 3V3A, single-phase, etc.
ZW8233C power monitoring instrument can be widely used in substations, distribution rooms, power plants, switchgear, and various power automation systems. It can be used independently or as a basic component in large-scale power management networks.
