I’m looking to buy a power supply which output these qualifications: 24V 5A.
I’m looking at 2 different ones and one of them has a different input outage than the other at 1.5A, while the other has 2A.
In: Technology
The input rating is the maximum that it is designed to draw. Your supply is a switch mode supply. The actual current will change with load, input voltage and efficiency. Your supply output is 120 watts maximum (24V x 5A). The input power at full load will be higher due to conversion losses. Many supplies can accept a wide range of AC voltage inputs, typically from 85 to 265 VAC. Lower voltage AC will cause it to draw more current than higher voltage. **The input current can be specified at the lowest voltage (highest current) or at a nominal voltage like 120 or 240 VAC. **
