When Selecting a DC Power Supply, Understand its Output Characteristic

Click image to enlarge

Figure 1: Output curve for an autoranging power supply compared with a power supply with a rectangular output. The autoranging supply provides higher output voltage, higher output current, and full power output at more V-I points.

­An important but overlooked aspect of power supply selection is the type of output characteristic that the power supply has. A typical power supply has a rectangular output in which maximum power is delivered only at the supply’s maximum rated voltage and maximum rated current. Another option is a power suppl
