Small, Lightweight Switchers Boast Of High Efficiency

Weighing in at less than two pounds and occupying just 26.5 in.3 of space, these new switching power supplies are designed to operate both at efficiencies greater than 97% and without thermal derating over a -40.25°C to 85.25°C temperature range. Their high efficiency coupled with the placement of the EMI filter and hold-up capacitors within the switcher enables the supplies to pack more power in a smaller form factor. In addition, the modular, PFC-corrected front-end modules are also said to generate less heat, eliminating the need for bulky cooling fans.
The first member of the new family of ac/dc power supplies is the Model OPS-U-500-385, a 500W unit having a universal, 85 to 264 Vac input and 385 Vdc output. Other features of the switcher include a 50/60 Hz operating frequency, input current limited to 5.5Arms, over-voltage protection, and UL, ULC, TUV and CE approvals. Future additions to the new switcher family are expected to be rated somewhere between 200W and 1,500W.
