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

Testing Times and the Most New Technology in One Place

Ally Winning, European Editor, PSD

Autumn is here and with that trade show time. This is an electronica year, and I’m looking forward to getting back to Munich and catching up with colleagues, as well as seeing what is new in the industry. Electronica is always very hard work, but there is nowhere else on earth that so much new technology can be

A Much-Appreciated Change of Seasons with a very Testy Topic

Jason Lomberg, North American Editor, PSD

­Welcome to the Fall, and a very special welcome to less extreme weather. After the brutal summer we’ve had, I’ve never been happier for a seasonal change (in fact, I think I’ve had reverse seasonal depression over the last several months). Then again, if my wife read this, she’d probably kill me s
