RP187-1-0-QD

Overview

The Astrodyne TDI RP187-1-0-QD is a single-output, open-frame DC power supply designed for industrial and commercial applications. It delivers a fixed output voltage of 12 VDC with a maximum current capacity of 15 A, resulting in a total power rating of 180 W. The unit features universal AC input compatibility, accepting line voltages from 85 to 264 VAC at frequencies between 47 and 440 Hz. Key electrical specifications include a line regulation of less than 0.5% and load regulation under 1%. The device incorporates comprehensive protection mechanisms including short-circuit, over-current, and over-temperature safeguards, ensuring reliable operation within an ambient temperature range of -10°C to +70°C.

Feature Summary

• Universal AC input capability supporting wide voltage and frequency ranges for global deployment
• Integrated multi-protection circuitry including short-circuit, over-current, and thermal shutdown
• Open-frame design facilitating easy integration into custom enclosures and OEM systems

Applications

• Industrial automation control panels
• Telecommunications equipment powering
• Medical device internal power modules

Procurement Notes

Verify the specific suffix codes on the datasheet to confirm terminal type and certification requirements. Ensure the selected variant matches the required input voltage range and regulatory standards for your target market. Cross-reference the pinout diagram with your system interface before procurement to avoid wiring errors.

Selection Notes

Select this model when a fixed 12 VDC output is required with up to 15 A continuous current. Consider the open-frame form factor if space constraints allow for direct mounting within a larger chassis. Evaluate thermal management needs based on the derating curve provided in the technical documentation for high-ambient environments.

Part Context

This component belongs to the RP187 series of open-frame switching power supplies by Astrodyne TDI. The series is engineered for high reliability in demanding environments. The 'QD' suffix typically denotes specific connector or terminal configurations distinct from standard screw-terminal variants within the same power class.

Replacement Considerations

Direct replacements must match the 12 V/15 A output specification and physical footprint. Verify that substitute models support the same universal input range and offer comparable protection features. Check for identical mounting hole patterns and terminal types to ensure mechanical compatibility without redesigning the host enclosure.
