Statistics show that about 25 percent of damages of electronic equipment are caused by overvoltages induced out of electromagnetic field during close lightning strikes. Video Surge Protector OPV-4 effectively protects 4 video lines, carrying away the stroke current to the ground. This way the excessive voltage is strongly limited and does not harm the video appliances. The device does not affect video signal quality and does not need any power supply.

ATTENTION! Before installation please read the following instructions:
  • OPV-4 is not symmetrical - the protected appliances must be connected to output (WY) BNC connectors. The inputs (LINIA...) have to be connected to the transmitting lines.
  • Any installation work cannot be performed during a thunderstorm.
  • OPV-4 requires good quality grounding installation.
  • The protector should be placed as near as possible to the guarded equipment.
This connection of OPV-4 allows to protect monitors or other devices (e.g. digital recorders)
