RP188-10-4.7-QD

Overview

The Astrodyne TDI RP188-10-4.7-QD is a single-output, open-frame DC-DC converter designed for industrial and commercial applications. It delivers a regulated output voltage of 4.7V at a maximum current of 10A, providing a total power capacity of 47W. The unit accepts an input voltage range of 9 to 36V DC. Key electrical specifications include a typical efficiency of 85% and a fixed switching frequency of 150kHz. The device features comprehensive protection mechanisms including over-voltage, over-current, and short-circuit protection, ensuring reliable operation in demanding environments.

Feature Summary

• Open-frame design suitable for integration into custom enclosures or OEM systems
• Integrated safety protections against over-voltage, over-current, and short circuits
• Fixed high-frequency switching for compact magnetic component sizing

Applications

• Industrial control systems requiring isolated DC power
• Telecommunications equipment power distribution
• Medical device internal power supplies
• Automotive electronics testing rigs

Procurement Notes

Verify the specific suffix 'QD' indicates the correct pinout and regulatory compliance status required for your target market. Confirm input voltage ranges match your system's available DC source. Ensure thermal management solutions are adequate for the expected ambient temperature and load conditions to maintain specified performance levels.

Selection Notes

Select this model when a low-profile, non-regulated input with a precise 4.7V output is needed. Compare against other models in the RP188 series if higher power or different voltage outputs are required. Consider the open-frame form factor for space-constrained designs where external housing is provided by the end product.

Part Context

This component belongs to the RP188 series of open-frame DC-DC converters from Astrodyne TDI. The series is characterized by high reliability and compact size, targeting applications where standard board-mount converters are insufficient but enclosed units are too large. The RP188 series offers various voltage and current combinations within its power class.

Replacement Considerations

Direct replacements must match the 47W power rating, 4.7V output, and 9-36V input range. Verify pin compatibility for through-hole mounting. Check if alternative manufacturers offer equivalent isolation voltages and protection features. Cross-reference part numbers with distributors for availability.
