1. What should I do if I can't find the paper manual in the product packaging?
Watchful Eye products is committed to going green with paperless data sheets. On the left side of each product enclosure is an engraved link with URL for downloading paperless data sheet and QR code of the website. If you need the paper data sheet, you can open the link and print the data sheet by yourself.
2. The advantages of LED status indicator?
If surge protection fails, the LED status indicator will be off, thus it can be seen intuitively, and the SPD can be replaced in time to avoid damage to the equipment caused by a second surge.
3. Can the length of the wire be customized?
Yes, the length of the wire can be customized, please specify in the order
4. Optional IP67, can I operate the order as following?
Please specify in the order (Note: IP67 refers to fully glue filling, which will increase the weight of the product)
5. Model WTH-SG/TL20PG-320 has no status indicator. What instruments can be used to test whether its surge protection function is normal or not?
Test with a Watchful Eye surge protector tester
6. Can you list more applications?
LED driver, network switches, computers, servers, air conditioners, refrigerators, inverters, precision instruments or other equipment which require fine surge protection, its front ends can also be integrated into the power supply module of the device or directly soldered to the PCB board during product production; further more, it can be directly connected in parallel in the terminal distribution box or wall switch
7. What is UL f1 standard for housing materials?
UL f1 standard requires housing materials be UV and acid rain resistant and can be used in outdoor environments
8. What are the advantages of MOV+GDT type surge protection?
No leakage current, slowing down the aging of MOV, avoiding the risk of burning or explosion caused by the increase of leakage current due to MOV aging.
9. What are the advantages of L-PE, N-PE, L-N full protection mode?
Finer protection, the residual voltage between each line is kept balanced, reducing the risk of surge voltage differences on equipment, which is crucial for precision instruments and other equipment, and key protection equipment in railways and other special industries, etc.
