ASP-150 Series - 150W Single Output PFC Open Frame PSU



ASP-150 is a 150W open frame type switching power supply (mainly AS-120P removed from the plastic case)and a new addition to our AC/DC product line. Featuring low no load power consumption and built-in active PFC function the units has been designed based ont he energy saving concern that is critical to consumer electronic applications. Thanks to the leading edge ZCS/ZVS technology the efficiency is as high as 90% and hence can provide 150W by only free air convection. ASP-150 mainly targets general industrial applications with space contraints as its 28.5mm low profile will fit prefectly in any 1U equipment.
