Protomaker 3D Printer Heat bed SSR test success. RAMPS 1.4 via 24 Volts using the above 24 Volt to 12 Volts method

3D Printer 24V Heat bed SSR test success

Using RAMPs 1.4, with a 12864 LCD display, control a 24 Volt 300 Watt heat pad.

The 24 Volt 300 Watt heat pad is controlled on and off via the Solid State Relay, SSR.

The Solid State Relay is controlled via the RAMPS 1.4 which is powered via a 24 Volt to 12 Volt car voltage step down device. A 24 Volt 500 Watt Power supply unit powers the 24 Volt 300 Watt heat pad via the Solid State Relay which is controlled via the RAMPS at 12 Volts.

So the RAMPS 1.4 is powered at 12 Volts via 12 Volts from the car voltage step down device which gets its 24 Volts input from the same 24 Volt 500 Watt Power supply as the one that also powers the 24 Volts 300 Watt heat pad.
