ESCRIPTIONS
The 1500WFR series is a family of low cost single and dual
output 15W DC/DC converters specifically designed for space-
critical applications. 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 switch-
ing 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/in
