Jännitteennieluri
Jännitteennieluri, often translated as voltage limiter or surge protector in English, is an electronic component or device designed to protect sensitive electronic equipment from overvoltage conditions. These overvoltages can be caused by external events like lightning strikes or power surges from the grid, or by internal transients generated by switching inductive loads. A jännitteennieluri functions by diverting excess voltage away from the protected circuitry, thereby preventing damage.
There are several types of jännitteennieluri, each with different operating principles and applications. Common examples include
The selection of a jännitteennieluri depends on the specific protection requirements, including the expected peak surge
