    Tips: What is the "kV" of an LED surge protector?

    The "kV" rating of an LED surge protector refers to the maximum voltage surge it can withstand or suppress. This rating is typically given in kilovolts (kV) and is an important specification when choosing a surge protector for LED lighting systems. Surge protectors for LED applications typically have kV ratings in the range of 2kV to 10kV or higher, depending on the specific model and the level of protection required.

    A higher kV rating indicates that the surge protector can handle larger voltage surges without failing or allowing the surge to pass through to the connected LED devices. LED surge protectors are designed to absorb, divert, or limit voltage surges, ensuring that the LEDs receive a stable and safe power supply, which helps prevent damage and premature failure.

    It's important to select a surge protector with an appropriate kV rating based on the potential surge risks in your electrical environment and the sensitivity of your LED lighting system to voltage spikes.
