Our statistics collected from many years of service show that about 25 percent of damages of electronic equipment was caused by overvoltages. Overvoltage induced out of electromagnetic field during close lightning strikes or short, rapid power stroke. The OPSD-5 overvoltage limiter is designed to Speed Dome cameras overvoltage protection.
ATTENTION! Before installation please read the following instructions: Any installation work cannot be led during thunderstorm. The OPSD-5 requires good quality grounding installation. The limiter should be placed as near as possible to the protected device.
