Our statistics collected from many years of service show that about 25 percent of damages of electronic equipment was caused by overvoltages. The OPV-4 overvoltage limiter effectively protects signal line carrying away the stroke current to the ground, due to above provides adequate overvoltage protection for electronic devices. The OPV-4 does not affect signal quality and is a passive device, no supplying is required.
ATTENTION! Before installation please read the next instructions: Limiter is not symmetric - the protected appliances must be connected to outputs (WY-1 to WY-4) BNC connectors. The inputs BNC LINIA have to be connected to the transmitting lines. Any installation work cannot be led during thunderstorm. OPV-4 requires good quality grounding installation. The limiter should be placed as near as possible to the guarded appliance.
