Power Supplies – Good, Better, Best

When it comes to selecting a power supply for your critical applications, Rockwell has many Switched Mode Power Supply options to consider. Efficiency can impact enclosure sizing, energy cost and reliability due to excess heat. Limited boost capacity can affect performance on stubborn equipment requiring high inrush on startup (ie., electronic contactor coils). And oversized supplies will increase acquisition cost, space required and energy consumption. But to keep things simple, we will review the good, better and best options and ways to keep your power supply running in the case of a failure.
