Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal block type and regulatory certifications. Ensure the input voltage requirements match your facility's power distribution network. Confirm that the physical dimensions and mounting hole patterns are compatible with your existing chassis or DIN rail assembly before finalizing procurement.

Selection Notes

Select this model when a reliable 20V DC source is required for moderate power loads up to 220W. Consider the thermal management capabilities if the unit will operate in enclosed spaces without active cooling. Evaluate the need for remote sensing if long cable runs are involved, as standard models may require external compensation for voltage drop across wiring.

Part Context

This component belongs to the RP220 series of switching power supplies manufactured by Astrodyne TDI. The series is engineered for robustness and reliability in critical applications. The 'QD' suffix typically denotes specific connector or terminal configurations within the product family, distinguishing it from other variants in the same power class.

Replacement Considerations

Direct replacements must match the 20V/11A output specification and similar footprint dimensions. Verify pinout compatibility if using existing cabling. Consult official substitution lists from Astrodyne TDI for cross-referenced models with identical electrical characteristics and mechanical constraints.
