VP-05 Series Type 3 Signal SPD
- Normal discharge current In (8/20 s): 5 kA
- Max. dischasrge current Imax (8/20 us): 10 kA
- Max. continuous operating voltage Uc: DC 8 V/ DC 32 V
- Online hot-swappable capability
- High current-carrying capacity, low limiting voltage, fast response time
- Low transmission attenuation, maximum transmission rate: 10 Mbps
Application:
The product series adopts a multi-stage protection architecture. The front stage utilizes gas discharge tubes (GDTs) to withstand high lightning current impulses, while the rear stage employs low-capacitance TVS diodes for fast response speed. It provides protection for 1-pair and 2-pair lines, effectively safeguarding communication signal equipment from transient overvoltage interference and damage.
