Surge protector (SPD) is an important power protection device used to protect electronic equipment from transient voltage interference and surge voltage in the transmission network. In daily procurement, how to distinguish the quality of surge protectors can be considered from the following aspects:

1. Check product certification and standards

Surge protector companies should provide product type test reports based on international/domestic standards (the quality standards and specifications of surge protectors are usually formulated in accordance with international and national standards). International standards include IEC, IEEE, etc., and domestic standards include GB, DL, etc. When choosing, you should ensure that the product meets the relevant standards and specifications. When purchasing, you should also pay attention to whether the product has passed the certification of authoritative organizations, such as CE, UL, TUV, etc. These certifications usually mean that the product has met the standards in terms of safety, performance and compatibility. Thor Lightning's surge protectors are produced in accordance with GB and IEC standards, and some models have obtained TUV product certification certificates.

2. Check the appearance

The appearance of a high-quality surge protector should be smooth and delicate, with no flash on the shell and a high flame retardant rating on the shell. The product identification parameters and other printings are complete and clear, and the printing quality is good. You can use a magnet to determine the metal material used in the surge protector. Conventional surge protectors are made of copper materials except for the screw terminals and the bottom rail clips. If they are all made of iron materials, you need to consider carefully when purchasing. You can judge by the color of the indicator window: observe the indicator window of the surge protector after unpacking. If the color is green, it means it is good; if the color is red, it means it is damaged.

3. Testing equipment

Verify the performance of the product under the detection of professional equipment. If there is no professional testing equipment, you can use a multimeter to measure the resistance: adjust the multimeter to the ohm range (RX100). If the resistance value is infinite, it means that the surge protector is good. Thor's lightning protection laboratory equipment has an 8/20μs compatible 10-350μs simulated lightning experimental impact platform to verify the actual performance of the product.

4. Refer to user reviews and word of mouth

Understand the evaluation of the product in the industry and understand the actual use effect and performance of the product. This can help you understand the advantages and disadvantages of the product more comprehensively. Choose brands and models with a good reputation. This usually means that the product has certain guarantees in terms of quality, performance and service. Thor surge protectors have been sold at home and abroad for more than ten years and are a reliable choice for users.

In summary, by checking product certifications and standards, checking product appearance, conducting actual tests, and referring to user reviews and word of mouth, you can preliminarily and effectively identify the quality of surge protectors. When choosing, you should consider the above factors comprehensively to ensure that you choose a surge protector that meets your needs.
