DC Supply Protector kit (fixed TH version)
A short-form kit to build the through-hole DC Protector with fixed overvoltage threshold (7.5-47.7V). Rated to handle up to 7A.
You just need to add zener diode ZD3 and resistors R1-R7 to suit your desired overvoltage threshold, as per Table 1 in the article.
See the link below for a complete list of parts included. Photo shows the assembled kit, including some parts that are not included.
The 13V zener diode included has a blue stripe added so you can tell it apart from the 15V part without reading the tiny markings.
Cat No SC6950. Price: AUD $20.00 1 |
