Top 5 Things You May Not Know About Power Supplies

1. A main trend in laboratory power supplies today is that, although the primary job of power supplies is making power, scientists want them using less of it. This is because, in many cases, improving power efficiency spurs more funding.

2. Many power supplies power devices scientists build themselves for experiments. Often, those devices are used only once or twice.

3. Power supplies have a huge range of applications which all require different voltages. For example, high voltage is required in equipment for sorting cells or separating compounds or DNA. Many chemical applications also need high voltage.

4. Overall, power supplies don’t need much attention. Once a power supply is in the system, unless it’s significantly abused, you don’t need to take care of it in any way.

5. In student labs, power supplies not only need to be easy to use, but bulletproof current limiting is also important, according to one professor, who recently told Lab Manager that, “Students do the weirdest things, like short the 5-volt supply to the 12-volt supply.” As an example, he says, “One power supply we used years ago failed in this mode by melting the solder holding the 12-volt regulator on the board!”
