TRN 3-2421SM Description

Short technical summary and product information.

The Traco Power TRN 3-2421SM is an isolated DC DC converter module designed for commercial ITE applications. It provides dual regulated outputs of +5V and -5V, each capable of delivering 300mA, for a total output power of 3W. The converter features a typical efficiency of 79% and includes short circuit protection (SCP) for reliable operation.

 

This module operates over a wide temperature range of -40°C to +85°C, making it suitable for demanding environments. The surface mount package measures just 11.9mm x 11.3mm x 8.0mm (0.47" x 0.44" x 0.31") and comes in a 7-SMD Module form factor, enabling compact board designs.

 

Designed for isolated power conversion, the TRN 3-2421SM is ideal for applications requiring a clean bipolar supply from a single input voltage. Its isolated topology ensures safety and noise reduction between input and output circuits.
