Solid State Relay – Kit

Description

Driver to connect to a 3D printer or other device to drive heated beds or loads with high current draw. The circuit proposed here, as sized, allows control of a maximum current of about 30A at 12V, even at particularly high ambient temperatures. There are also two connectors: the first, called JP1, allows selecting the logic of the control signal by inserting a jumper between the center and one end. If the signal that activates the bed is negative, the jumper must be positioned toward “IN_N”, while if positive, toward “IN_P”. Consequently, based on the choice made, the signal must be connected to connector CN1: if “IN_N” is selected, the control signal must be connected to terminal “N”, otherwise to “P”. The package also includes 4 faston connectors to crimp on the cables for making connections.
