celduc relais is offering Solid State Relays with different types of Inputs.
Here are the possible types of DC control Solid State Relays :
Here are the possible types of AC control Solid State Relays :
For both AC and DC inputs Solid State Relays, we are offering SSRs with current regulator which limits the input current to vary much with input voltage.
You can easily recognize these versions thanks to the « Input : Ic = f( Uc) » curve on our technical data-sheets which looks like this :
