SSR Input Current

#1

In the schematics provided for the injection and compression molder , only the input voltage (3-32 V) and output voltage (24-380 V) were mentioned.

I still couldn’t purchase an SSR because it comes in different variants depending on the current. The variants include: 10 A, 15 A, 25 A, 40 A, 50 A, 60 A, and 75 A.

Need help in deciding which to choose.

Thank you guys! 🙂

It depends on the heaters you use.

I use 4 x 300W heaters on 220V. So it draws 5.5A during normal operations. But to play safe I just buy a FOTEK-40A (capable of 40A) because there are Chinese counterfeit products.
