General Descripon

The TRACO TRA 1 series is a new range of isolated 1W DC/DC converter modules in a small SIP-package. There are 24 models

available with 5V, 12V or 24VDC input and single-or dual-output voltages. These products provide have a typical load regulation of

2.5% to 5.0% depending on model.

The TRA1 DC/DC converters are a compromise between a more expensive fully regulated converter and a non-regulated

converter. They offer the designer a new solution for many cost critical applications where the output voltage variation has to be

kept in a certain limit under all load conditions.

Application Note TRA 1 Series Safety and Installation Instruction Fusing Consideration Caution: This power module is not internally fused. An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of sophisticated power architecture. To maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse.
