Characteristics Description
Damage Level Input voltage at 1 MW
×1: 300 V (DC or peak AC)
derate to 5 V (DC + peak AC) at 20 dB/decade above 10 kHz
×10: 300 V (DC or peak AC)
derate to 5 V (DC + peak AC) at 20 dB/decade above 10 MHz
×100: 300 V (DC or peak AC)
derate to 5 V (DC + peak AC) at 20 dB/decade above 10 MHz
Input Voltage at 50 W = 5 V (0.5 W) maximum
