RP125-30-0-W

Overview

The Astrodyne TDI RP125-30-0-W is a single-output, regulated DC power supply designed for industrial and commercial applications. It delivers a nominal output voltage of 30 VDC with a maximum current capacity of 4.2 A, resulting in a total power rating of 125 W. The unit features an input voltage range of 85 to 264 VAC and operates at line frequencies from 47 to 440 Hz. Key electrical specifications include a line regulation of less than 0.5% and load regulation of less than 1%. The device incorporates comprehensive protection mechanisms including short-circuit, over-current, and over-temperature protection, ensuring reliable operation under varying load conditions.

Feature Summary

• Regulated DC output with high efficiency and low ripple noise characteristics
• Integrated protection circuits for short-circuit, over-current, and over-temperature safety
• Wide input voltage acceptance supporting global AC power standards
• Compact metal enclosure design suitable for panel or DIN-rail mounting

Applications

• Industrial automation control systems
• Telecommunications equipment power backup
• Medical device instrumentation
• Test and measurement laboratory setups

Procurement Notes

Verify the specific suffix codes against the manufacturer's latest datasheet to confirm pinout configuration and regulatory certifications. Ensure the input voltage requirements match the local power grid specifications before deployment. Confirm that the thermal management environment allows for adequate airflow around the heat sink surfaces to maintain safe operating temperatures during continuous duty cycles.

Selection Notes

Select this model when a stable 30 VDC source is required for loads up to 4.2 A. Consider the physical dimensions and mounting style compatibility with existing chassis designs. Evaluate the need for remote sense capabilities if long cable runs are involved, as standard models may not include this feature unless specified. Verify that the environmental temperature range aligns with the installation site conditions.

Part Context

This unit belongs to the RP125 series of switching power supplies manufactured by Astrodyne TDI. The series is engineered for general-purpose industrial use, offering a balance of performance and durability. The 'RP' designation typically indicates a regulated power supply, while the numerical values denote power and voltage ratings respectively within the product family structure.

Replacement Considerations

Direct replacements must match the 125 W power rating, 30 V output voltage, and 4.2 A current capacity. Verify mechanical footprint compatibility for direct swap installations. Check that replacement units offer equivalent protection features and regulatory approvals such as UL, CE, or IEC standards relevant to the target market.
