LIGHTNING STRIKE COUNTER DK-JS7 ANALOG

Lightning Strike Counter DK-JS7 Analog

Lightning strike counter is a universal counter. When the lightning protection circuit system is normal, no current flows on the discharge line, and the lightning strike counter does not count; when lightning current discharge occurs in the line, the lightning protection circuit discharges lightning current to the ground, and there is current on the discharge line. When it flows through, the counter is coupled to the induced voltage, causing the counter to count.

Lightning strike counter is suitable for all SPDs, lightning rods, etc.
It can sense and discharge lightning current,
and the cumulative number of lightning strikes is displayed on the counter.
The product counts accurately and does not
malfunction; it works without power supply, the counting value will not be lost for a long time, and cannot be reset to zero; it has dust-proof, waterproof and other functions.
