Our Technical Support team will be out of the office on Wednesday, April 23 starting at 12pm. Tech Support will reopen with normal hours on Thursday, April 24 at 9am. Thank you
Description: A solid state relay (SSR) is just what it sounds like; an IC that acts like a mechanical relay. They allow you to control high-voltage AC loads from lower voltage DC control circuitry. Solid state relays, however, have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there's no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.
This kit has everything you need to make use of an SSR in your next high-voltage project. After soldering together the through-hole kit, simply attach your AC load and switch it on and off using your microcontroller. This is a great kit for through hole soldering practice and is really handy for controlling lights, water pumps, fans or any other intermittent high-voltage device.
Note: These work with AC loads only. Great care, safety, and knowledge should be used with high current and voltage.
