SSR Relay Module works only with AC loads, need DC switching solution

Customer:

I purchased the SSR Relay Module intending to use it to switch a small water pump on and off. The pump also comes from your store. From the specifications, I see that the SSR relay can only work with AC loads, but the small pump requires DC voltage (5V). Do you have a relay that can switch DC loads?

Kupio sam https://e-radionica.com/hr/modul-s-ssr-relejom-1-kanalni.html sa ciljem da relej koristim za paljenje i gasenje male pumpe za vodu takodjer kupljene kod vas. Problem je u tome sto koliko vidim po specifikacijama - vas SSR relej moze raditi samo sa izmjenicnim potrosacima - a mala pumpa treba istosmjerni napon (5V). Moje pitanje je - da li imate nekakav relej koji moze paliti i gasiti istosmjerne potrosace?

Soldered Support:

Unfortunately we do not have an SSR relay module for DC loads. You can use a classical mechanical relay or use a MOSFET as a switch.

hvala Vam na upitu. Imamo klasični mehanički relej ili možete koristiti mosfet kao switch. Kolega mi je napomenuo da je odgovorio na Vaš upit na forumu.
