RP185-10-1-W

Overview

The Astrodyne TDI RP185-10-1-W is a high-performance, single-output AC-DC power supply designed for demanding industrial and medical applications. It delivers a regulated 10V DC output at up to 18.5A, providing 185W of continuous power. The unit features a universal input voltage range from 85 to 264VAC, ensuring global compatibility. Key electrical specifications include a maximum efficiency of 90% and a power factor greater than 0.95 at full load. It operates within a temperature range of -40°C to +71°C with derating, housed in a compact metal enclosure suitable for panel mounting.

Feature Summary

• Complies with stringent IEC 60601-1 third edition safety standards for medical equipment
• Features active power factor correction (PFC) for improved energy efficiency and grid compatibility
• Includes comprehensive protection mechanisms such as over-voltage, over-current, and short-circuit protection
• Designed for high reliability with low ripple and noise performance suitable for sensitive electronics

Applications

• Medical imaging systems requiring certified isolation and safety compliance
• Industrial automation controllers and PLCs operating in harsh environments
• Telecommunications infrastructure equipment needing stable high-power DC rails
• Laboratory test and measurement instruments requiring low-noise power delivery

Procurement Notes

Verify the specific suffix codes on the datasheet to confirm exact pinout configurations and connector types required for your integration. Ensure that the ambient temperature conditions do not exceed the derating curves specified in the thermal management section. Confirm regulatory certifications relevant to your target market, such as UL or CE marks, are present on the final product label before deployment.

Selection Notes

Select this model when a single 10V rail is required with high current capacity exceeding standard 12V options. Consider the physical dimensions and mounting hole patterns against your chassis constraints. Evaluate the need for remote sense capabilities if long cable runs are involved, though this specific variant may require external wiring for precise regulation. Compare total cost of ownership including thermal management requirements against alternative voltages.

Part Context

This component belongs to the RP185 series, which offers various voltage outputs ranging from 5V to 48V while maintaining consistent 185W power density. The series is engineered for applications requiring robust performance in confined spaces. The 'W' suffix typically denotes specific packaging or terminal style variations within the manufacturer's lineup, distinguishing it from screw-terminal or wire-lead versions.

Replacement Considerations

Direct replacements must match the 10V/18.5A output specification and maintain IEC 60601-1 compliance if used in medical contexts. Verify footprint compatibility and pin-to-pin correspondence to avoid redesigning the PCB or enclosure. Check if adjacent models in the same series offer identical thermal profiles and protection features to ensure seamless substitution without compromising system safety margins.
