High-Density AC-DCs Offer Up To 93.5% Efficiency

Telecom, ITE, and industrial equipment are target applications for the 360-W CFM361S series of ac-dc power supplies that combine high power density with efficiency that tops out at 93.5%. The devices, developed by Power Sources Unlimited, come in single 12-, 24-, and 48-V output models with 5 VSB (standby) at 500 mA and 12-V fan output at 300 mA. Universal input (with active PFC) ranges from 90 to 264 V ac, and operating temperature ranges from −20°C to +70°C (open frame) or −20°C to +85°C (enclosed). All devices also feature remote voltage sense and on/off remote control. The footprint for open-frame versions measure 3 by 5 by 1.6 in., while the optional U-frame/cover measures 3.4 by 5.4 by 1.7 in. All models are approved to UL/EN60950-1, EN55022 Class B standards and carry the CE Mark (LVD).
