Why is it vital to include power factor in ac-dc efficiency measurements?
Ron Stull of CUI explains what power factor is, how it affects efficiency calculations and how it is measured With today’s concentration on energy savings, design engineers need to know with increasing accuracy what their ac-dc power converter efficiency is. Measuring the ratio of output power to input power is simple for dc-dc converters, but […]
Modular dc supplies target smart home and IoT apps
The RAC15-K and RAC20-K series are designed for low-power IoT and household applications. These ac/dc modules have ultra-low energy losses especially in light load conditions and minimal standby power consumption. Based on the footprint of the compact RAC10-K modules, these new modules feature high-efficiency over a wide load range. This makes them candidates for the […]
