Detailed Specifications
Eaton PR40 Trim Line 40A 13.8VDC Regulated Power Supply
Overview
The Eaton Tripp Lite PR40 is a precision-regulated DC power supply engineered to provide a stable 13.8V DC output from a standard 120V AC input. This robust unit is specifically designed for environments demanding clean, consistent power, such as commercial and land-mobile radio systems, amateur radio setups, test benches, and point-of-sale installations. Its core purpose is to reliably convert alternating current into direct current, safeguarding connected DC-powered equipment from fluctuations and potential damage. Utilizing a solid-state, integrated circuit design, the PR40 maintains exceptional output voltage regulation, ensuring that sensitive applications receive uninterrupted and precise power. Key technical features include crowbar overvoltage protection, which instantly guards against damaging voltage spikes, and an automatic time-controlled overcurrent protection system that prevents overloads. These protective mechanisms enhance the longevity and reliability of both the power supply and the critical equipment it powers. With its efficient design, the PR40 features a compact footprint, optimizing operating space in various deployments, from fixed base stations to crowded test environments. Large internal heat sinks and a vented cabinet ensure continuous cool operation, contributing to a long service life. Installation is straightforward, with the unit typically deployed as a standalone benchtop power source, seamlessly integrating into existing infrastructure where reliable AC-to-DC conversion is paramount.
