TES 3-2421WI

Product Overview

The Traco Power TES 3-2421WI is a surface-mount isolated module DC DC converter that provides two outputs, +5 V and -5 V, from a 9 V to 36 V input range. The module is rated for 3 W output power and offers a 1.5 kV isolation rating. Its 24-SMD module package, 12 leads, and 32.2 mm x 14.8 mm x 10.2 mm body support board-level integration where a split-rail isolated supply is required. Remote on/off control and short-circuit protection are included, and the converter is specified for operation from -40°C to 71°C with 78% efficiency.

Key Features

• Two isolated output rails: +5 V at 300 mA and -5 V at 300 mA.
• Input range of 9 V to 36 V for board-level DC DC conversion.
• 3 W rated output power with 78% efficiency.
• 1.5 kV isolation rating.
• Remote on/off control and short-circuit protection (SCP).
• Surface-mount 24-SMD module package with 12 leads and dimensions 32.2 mm x 14.8 mm x 10.2 mm.
• Operating temperature range of -40°C to 71°C.

Applications

• Commercial information technology equipment requiring isolated +5 V and -5 V board power.
• Isolated split-rail power for board-level subsystems operating from a 9 V to 36 V DC input.
• Compact surface-mount assemblies requiring 1.5 kV isolation, remote on/off control, and short-circuit protection.

Design & Procurement Notes

For board design, confirm that the 24-SMD module footprint and 12 leads fit the assembly and that the 9 V to 36 V input is compatible with the upstream supply. The +5 V and -5 V outputs each provide 300 mA, so total load requirements should be checked against the 3 W rating. The 1.5 kV isolation rating supports separated power domains, while remote on/off and short-circuit protection should be integrated into system control and fault handling. The -40°C to 71°C operating range and surface-mount construction should be considered for thermal layout.
