Didnt work with other relays so I cant give You advice which one to buy, I hooked up Automotive relay 12V 50A that is low cost works like a charm (printing 12 hours a day for a month now with no problems) but if You need help with wiring, any relay that Youby smoothol - Reprappers

Quotedc42 Quotesmoothol Quotedc42 For a heated bed of that size, you should use one of the following: 1. AC mains voltage bed heater, driven using a DC-AC SST. Only do this if you are knowledgeable about and comfortable with doing mains voltage wiring. 2. A 24V bed heater (in which case you may as well run the entire printer on 24V, assuming you use 24V-capable electronics). The bed heater willby smoothol - Reprappers

QuoteBeer4Brew Guys thx for all help but if You want silicone heated bed and You have some prusa i3 variant You can do like me I use 12V 360W 30A power supply for LED lights bought for 30$ sillicone heater 12V 280W that I hooked up to automotive relay g.cartier 12V 50A and I dont have extra power supply just hooked it up to that power supply for my prusa and thats it in a minute my bed gets hot tby smoothol - Reprappers
