DECO2017SEO-00007

Overview

The DECO2017SEO-00007 is a 280W open-frame AC/DC switching converter from the TDK-Lambda CSS series. It accepts a single-phase input voltage range of 90 to 264Vac and delivers a fixed 12Vdc output with a maximum current of 23.33A. The unit features a typical efficiency of 91% and measures 76.2mm x 30mm x 127mm, conforming to the 3x5 inch industry standard size. It operates within a temperature range of -20°C to 70°C using forced or natural convection cooling.

Feature Summary

• Complies with medical safety standards requiring 2MOPP isolation
• Offers flexible thermal management via forced air or natural convection cooling options
• Provides high power density in a standard 3x5 inch open-frame chassis

Applications

• Medical equipment requiring certified isolation barriers
• Industrial control systems needing robust AC/DC conversion
• General purpose power supply modules for rack-mounted systems

Procurement Notes

Verify that the specific order quantity matches the manufacturer's production status, as this model is listed under a non-recommended new design status. Confirm that the required cooling method (forced or natural) aligns with the specific variant ordered, as thermal performance depends on airflow configuration. Ensure all safety certifications such as IEC60601-1 are valid for the target region and application class before finalizing procurement.

Selection Notes

Select this converter when medical-grade isolation (2MOPP) is mandatory for system safety compliance. Consider the physical dimensions of the 3x5 inch form factor against available chassis space. Evaluate whether forced air cooling is necessary based on ambient temperature constraints, as natural convection may limit thermal headroom in enclosed environments compared to active cooling solutions.

Part Context

This component belongs to the TDK-Lambda CSS series, which focuses on open-frame AC/DC converters designed for integration into larger systems. The series emphasizes compliance with stringent international safety standards, particularly for medical applications. The DECO2017SEO-00007 represents a mid-power option within this lineup, balancing output capacity with standardized mechanical footprints for easy retrofitting.

Replacement Considerations

The CUS400M series is officially recommended as an alternative. Note that compatibility is not guaranteed between these models. Verify electrical parameters and mounting dimensions carefully before substitution.
