KGZW-30B Power Harmonic Tester

ลักษณะผลิตภัณฑ์
1, ปลอดภัยและเชื่อถือได้
The voltage input adopts a high voltage isolation module (2000วี, response time ≤2μS), and the current input adopts a AC current clamp (0 ~ 50 กิโลเฮิรตซ์,0 ~ 5Arms) to isolate the input signal from the measurement system. This not only makes KGZW-30B safe, reliable and convenient in use, but also greatly improves the anti-interference ability.
