The fine protection is effected exclusively by a RLC low-pass filter and a high performancesuppressor diode with Fail-safe function.There are no significant leakage currents due to the absence of varistors (MOV).Application:The EnerPro..V-Tr with low voltages from 12V to 60V has been designed for the protection of power supplieswith power consumption up to 6A, for highly sensitive electronic equipments.Due to their wide operating voltage range (from 12 V up to 60 V DC), their high impulse discharge capacity(line-to-ground: 20 kA at wave 8/20 µs) and to their easy installation on either mounting plate or 35mm DINrail, this SPD can be used universally also for AC current supplies.This SPD type serves as a. lightning and surge protection for DC or AC low voltage power supplies up to 6Apower consumption. For installation between the boundary 2-3, according to the LPZ conception of IEC EN62305 part 1-4. (VDE V 0185 Teil 1.-4)Protects People and Valuables
