Procurement Notes

Verify the specific ordering suffix matches the required input voltage range and connector type. Confirm that the ambient operating temperature limits align with your installation environment. Ensure compliance with local electromagnetic compatibility regulations before deployment. Cross-reference the datasheet revision date to guarantee access to the latest safety certifications and technical updates.

Selection Notes

Select this model when a fixed 20V output is required with up to 225W capacity. Consider the physical dimensions for panel mounting constraints. Evaluate the need for remote sensing if long cable runs are involved, as standard models may require external compensation. Verify that the input frequency range matches the local power grid specifications to ensure optimal performance.

Part Context

This unit belongs to the RP series of regulated switching power supplies from Astrodyne TDI. The series is engineered for reliability in demanding environments. The RP225 variant specifically targets applications requiring moderate power density with high stability. It serves as a core component in systems where consistent voltage delivery is critical for operational integrity.

Replacement Considerations

Direct replacements must match the 20V/11.25A output specification and similar form factor. Verify pinout compatibility if direct plug-in substitution is intended. Check that the replacement unit meets or exceeds the original safety isolation ratings. Consult manufacturer cross-reference lists for verified equivalent part numbers.
