VPT Unveils the VXR125-27000S DC-DC Converter

VPT, Inc., a part of the esteemed HEICO corporation, has recently announced its latest product: the VXR125-27000S, which is poised to revolutionize the landscape of DC-DC converters. As the inaugural model with a 270 V input in the renowned VXR series, this innovative converter is designed for high reliability and exceptional performance in critical applications.

Elevated Performance and Efficiency

The VXR125-27000S is engineered to deliver an impressive 125 W of output power, operating efficiently across a broad input voltage range of 160 V to 400 V. This wide operational span ensures flexibility and adaptability, making it suitable for various applications in the military, aerospace, and other high-stakes environments.

Efficiency is a key feature of the VXR125-27000S, boasting an operational efficiency of up to 89%. This level of efficiency exceeds many comparable solutions, providing enhanced performance and reduced heat generation, which is crucial in high-demand scenarios. Its improved transient response is facilitated by VPT's regulated isolation stage design, further solidifying its position as a leader in power solutions.

Robust Design for Rugged Environments

One of the standout features of the VXR125-27000S is its V-SHIELD® packaging, known for its epoxy-encapsulated design that offers exceptional protection against harsh chemicals and environmental factors. The dual-sided conduction cooling method simplifies thermal management, making the device easier to integrate into existing systems.

Moreover, its six-sided metalized shield optimizes electromagnetic interference (EMI) performance, a critical factor for devices used in military and aerospace sectors. This aspect, coupled with the converter's compatibility with high-volume assembly techniques such as wave soldering and aqueous wash, facilitates efficient manufacturing processes.

Simplified System Integration

The design of the VXR125-27000S promotes streamlined system integration, requiring no external components for stability. This significantly lowers the part count and minimizes design complications, ultimately reducing time and costs associated with system development. Operating at full power without derating at temperatures up to +105 °C, the VXR125-27000S guarantees reliability and consistent performance, even in extreme thermal conditions.

Each unit undergoes a rigorous 96-hour burn-in test at +105 °C as part of VPT's strict screening procedures. This ensures that every converter meets the high reliability standards expected in mission-critical applications.

Compliance with Military Standards

VPT aims to meet and exceed industry specifications, as the VXR125-27000S is qualified to several military standards, including JESD22, MIL-STD-810, and MIL-STD-883. The device is designed to withstand shock, vibration, and temperature fluctuations, ensuring it performs exceptionally well under challenging conditions. Additionally, it adheres to RTCA/DO-160 Section 16 requirements, making it an excellent choice for both military and commercial aviation applications.

When paired with the appropriate VXRF2-270 EMI filter, the VXR125-27000S also meets compliance with MIL-STD-461 and other relevant sections of RTCA/DO-160, reinforcing its suitability for rigorous operational needs.

Availability and Future Prospects

The VXR125-27000S is now available for purchase through VPT's U.S. e-commerce platform, with plans for international distribution soon to follow. This new addition to the VXR family not only enhances VPT's product offerings but also reflects the company's commitment to providing powerful and rugged solutions tailored for critical systems.

VPT, Inc. has built a reputation for being at the forefront of innovative DC-DC power converters and EMI filters, serving key players in various industries such as NASA, Lockheed Martin, Boeing, and BAE Systems. With the launch of the VXR125-27000S, VPT continues to lead the charge in delivering high-reliability solutions that power essential systems across the globe.
