Product Description
KDCX1-20-8000 arrester monitor has three counters,It can collect different waveforms, When 2㎳ square wave ≤600A or other waveform, the first counter counts; When the square wave is 600A~1500A, the second counter counts; When the square wave is ≥1500A, the third counter counts. It also has RS485 remote transmission function, which can transmit impulse current waveform information, full current information, and operation frequency information to the background, and waveform information rising edge and bandwidth error is less than 5%, amplitude error is less than 5%; It can recognize impulse current signals with pulse widths up to 20㎳, and built-in high-precision clock chip, in the case of no time, the one-year clock error is less than 3s.
