Caracteristicas de producto
1, seguro y confiable
The voltage input adopts high voltage isolation module (2000V, response time < 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, fácil de usar
Portable structure, talla pequeña, peso ligero, 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, alta precisión
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.
