The new ultra-compact RACM550-G series from Recom is designed to support up to 300 W of continuous output power without cooling fans. This highly efficient 3×5-in baseplate-cooled design measures just 38 mm total height and enables direct heat dissipation through metal housings in the end application. Up to 550 W of peak power with nominal […]
Can a three-phase power supply operate from wye and delta ac inputs?
A few guidelines help clarify what three-phase input voltage best suits a particular large power system. TDK Lambda Technical Marketing AC-DC power supplies rated higher than 2.5 kW frequently have a three-phase ac input. In the U.S. the voltage can be 208/220 Vac or 480 Vac. In Europe, it is a “harmonized 400 Vac” which […]
