RA-V7SERIES ●RA-V7 The RA-V7 Series utilizes micro-gap discharge technology, thus demonstrating extremely fast response characteristics in dark ambient conditions without the use of radioactive isotopes. Applied as indirect lightning surge protection in the power line of equipment, this model is used with a series connected MOV between line and ground in the power line. It may also be used within electronic circuits to protect from destructive impulse current while still permitting “Voltage Withstand Testing”without having to remove the RA-V7. UL UL CSA Safety Approvals : UL-1449 : UL-1414 : C22.2 No. 1 : IEC 384-14 File No . E143446 E47474 LR105073 J9551103 FEATURES： ● Fast response time（see V-T Chart） ● This Surge Absorber is Bi-polar and will fail open if surge withstand capability is exceeded. ● Inter-terminal capacitance is extremely small, resulting in little influence on electronic circuits. ● High Insulation Resistance（1×10 9 min.） ● Excellent Surge withstand capability （300 times at 100Amp, 8×20μs.） ● Small size for compact circuit design. ● Available taped for auto insertion.
