SMG3000 портативті қол фазалық вольтамперметрі

Өнімге кіріспе

The Three-Phase Phase Voltmeter is designed for measuring three-phase electrical parameters. It enables high-precision measurement of voltage, current, phase angle, frequency, power, power factor, and other electrical parameters in three-phase systems.

The instrument features a high-speed Cortex M3 processor combined with a 24-bit high-speed ADC for accurate measurement and calculation of electrical parameters. It is equipped with a fully graphical user interface and a true-color display with a resolution of 320×240.

Өнім сипаттамалары

1. High Measurement Accuracy: Voltage and current accuracy up to Class 0.3; phase accuracy up to ±0.3°.

2. Multiple Measurement Modes: Supports single-phase, two-phase, and three-phase measurement modes, as well as three-phase four-wire and three-phase three-wire configurations.

3. Harmonic Analysis: Measures harmonics up to the 21st order for both voltage and current.

4. Automatic Real-Time Measurement: Operators only need to complete the wiring, and the instrument automatically measures and updates data in real time, facilitating on-site analysis.

5. Complete Isolation Technology: Adopts full isolation technology to prevent safety accidents.

6. Comprehensive Power Measurement: Measures active power, reactive power, apparent power, three-phase power, and power factor.
