24V DC Power Supply Calculator
Size a 24V DC supply with load and design margin. Fast, browser-local and free to use.
Enter one line per load as device, total amps. If you have five sensors drawing 0.1 A each, enter Sensors (5),0.5.
Example: PLC,0.5
Use 20–30% for future additions and normal design headroom. Consider more for high inrush loads.
