Our statistics collected for many years in the service indicate that about 25% of damage to electronic equipment was caused by overvoltagesThe OPZ-12 surge limiter effectively protects the transmission line enabling the discharge of surge current to the ground, which provides proper surge protection of electronic devicesThe device protects against damage to switched-mode power supplies, and against overvoltages in the power lineOPZ-12 is a passive device that does not require Power
REMARK! Before installation, please read the following recommendations: OPZ-12 is not symmetrical has a cable with a power plug to which we connect the protected device \"12V output\". On the other hand, the connection terminals \"12V input (LINE)\" are connected to the power transmission line, on which an overvoltage may occur. Attention should be paid to the correct connection of terminals: (+) and (-). Incorrect connection may damage the camera. The device has an LED indicating that the supply voltage is correctly connected. Connection work cannot be done during a storm. OPZ-12 should be connected to a good grounding installation. The stop should be placed as close as possible to the protected device
