Counts various surge occurrences on AC power lines of 100 to 320V at 50Hz/60Hz! AC power surge counter!

The J2S-320C is a surge counter for AC power supplies. - It counts the number of various surges occurring on power lines of AC 100-320V 50Hz/60Hz. - Counting can be done simply by connecting it in parallel with the AC power supply. - It supports lightning surge (LFS), power switch surge (PSS), inrush current (SIC), electromagnetic pulse (EMP), and continuous spark surge (SSS). - It counts up when it detects surge voltages from 400V to 10kV. - The counting range is from 0 to 99,999,999. - It is powered by a built-in battery, allowing for flexible installation (the built-in battery can be used for about 5 years). - Impulse resistance is 1.25/50μS: 6kV and 8/20μS: 3kA. - It can be directly fixed with screws or mounted on a DIN rail using the included DIN rail adapter. - The continuity of the AC power supply can be easily checked with the LED on the top.

Applications/Examples of results

By installing the J2S-320C alone or together with a SEAT-type surge protector on the AC power line where you want to count surges, you can count the number of various surges. Please connect the white wire of the J2S-320C to the N (Neutral) of the AC power supply and the black wire to the L (Live). If a voltage of 100V or more is present on the AC power line, the green LED on the surface of the J2S-320C will light up.
