เครื่องนับกระแสฟ้าผ่าช่วงกว้าง, เครื่องบันทึกเหตุการณ์ LPS รูปคลื่นคู่ 500A-100kA
Wide-range lightning current counter complying with IEC 62561-6, compatible with both 8/20μs induced surges and 10/350μs direct lightning waveforms. Minimum trigger current 500A captures faint switching impulses, while max withstand capacity reaches 100kA (8/20μs) and 50kA (10/350μs) for heavy lightning strikes, without counting deviation after repeated high-current impacts. Self-powered lithium battery enables years of unattended logging, equipped with time lookup, count
