VP-05 Series Type 3 Signal SPD, VOZWEI
SPD according to EN/IEC 61643-11: Type 3
Max. continuous operating voltage Uc: DC 8 V
Impulse current Iimp (10/350 μs): 0.5 kA
Nominal discharge current In (8/20 μs) : 5 kA
Max. discharge current Imax (8/20 μs): 10 kA
Voltage protection level Up: L-L ≤ 30 V
L-PE ≤ 75 V
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.
Featured:
* 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
* Online hot-swappable capability
* High current-carrying capacity, low limiting voltage, fast response time
* Low transmission attenuation, maximum transmission rate: 10 Mbps
