These models operate from wide (2:1) input voltage ranges of 18 to 36 or 36 to 72 VDC; and provide regulated outputs of 5, 12, 15, ±12 or ±15 VDC. Standard features include 500 VDC input/output isolation, an internal input filter, line/load regulation of ±1.0% and a minimum switching frequency of 190 kHz. All models are packaged in compact, low profile 1” X 2” X 0.4” inch metal case. This miniature size yields a power density as high as 18.75 watts/in3. Operation is specified over the full operating temperature range of -25 oC to +71 oC. Cooling is by free-air convection.
