ESCRIPTIONS
The 3000WFR series is a family of compact 25W to 30W, high
performance DC/DC converters. These converters are
specifically designed to provide the flexibility, power density,
and reliability required to fulfill local power needs in
applications ranging from telecom switch systems to
portable instrumentation. 27 models operate over 2:1 input
ranges of 9 to 18, 18 to 36 or 36 to 72 VDC; providing single,
dual or triple output combinations of 3.3, 5, 12, 15, ±5, ±12,
±15, 5±12 and 5±15 VDC. All models are packaged in
compact, low profile 2.0” X 2.0” X 0.4” metal cases.
