Máy phân tích chất lượng điện KDZW-35D

1, safe and reliable The voltage input adopts high voltage isolation module (2000V., thời gian đáp ứng < 2μS), and the current input adopts alternating current clamp (0 ~ 50KHz,0 ~ 5Arms) to isolate the input signal from the measurement system. This not only makes KDZW-35D safe, reliable and convenient in use, but also greatly improves the anti-interference ability of KDZW-35D.

2, easy to use Portable structure, kích thước nhỏ, trọng lượng nhẹ, one person can carry the instrument to the field test; The built-in high-performance lithium battery can work continuously for ten hours without external power supply, and can also carry out high-precision measurement under charging.

3, high precision Data acquisition channel adopts single channel single A/D design, each channel has A 16-bit parallel A/D, all channels are completely synchronous sampling, higher precision, faster, and any A/D damage will not affect the normal data acquisition of other channels.

4. Strong software function Using DSP+ARM+CPLD kernel, the processing speed is fast, the software functions are rich, so that KDZW-35D is suitable for complex test work and data processing work, greatly improving the test efficiency and level. The panel of the device is equipped with a large screen color display to graphically display real-time data of main power quality monitoring indicators.

5. Communication interface The tester provides USB interface to facilitate data storage and communication with the computer for data transmission.

6. Many test parameters 1) Basic measurement Grid frequency; Effective value of voltage and current; Total active power, reactive power, power factor. 2) Basic monitoring indicators a) three-phase fundamental voltage, current RMS, fundamental power, power factor, phase, vân vân.; b) voltage deviation; c) Frequency deviation; d) three-phase voltage unbalance, three-phase current unbalance, negative sequence voltage, hiện hành; e) Harmonics (2 ~ 63 lần). Including voltage, current total harmonic distortion rate, each harmonic content rate, amplitude, phase; Active and reactive power of each harmonic; 3) Advanced monitoring indicators a) Voltage fluctuation, flicker;

7. Large capacity storage Harmonics tester built-in 32MB memory, users can configure different save time steps, 5 giây, 15 giây, 30 giây, 1 phút, 2 phút, 5 phút, 15 phút, 30 minutes and so on.
