VPT Introduces the VXR125-27000S DC-DC Converter

In a significant advancement in the field of power conversion, VPT, Inc., a subsidiary of HEICO Corporation, has announced the release of the VXR125-27000S, marking the first model in its VXR Series capable of handling a 270 V input. This innovative DC-DC converter is engineered to deliver a robust output power of 125 W and is operational over a wide input voltage range of 160 V to 400 V. This versatility makes it an ideal solution for various applications, particularly in challenging environments.

Features and Design Enhancements

The VXR125-27000S boasts VPT's exclusive V-SHIELD® packaging, which is epoxy-encapsulated for heightened resistance against chemicals and environmental factors. A standout feature is its dual-sided conduction cooling, which simplifies thermal management. Moreover, the converter incorporates a six-sided metalized shield for improved Electromagnetic Interference (EMI) performance, ensuring its compatibility with high-volume assembly processes like wave soldering and aqueous washing.

VPT focuses on system efficiency; hence the new converter eliminates the necessity for external components to achieve stability. This design strategy not only reduces the part count but also lowers complexity in the system design, making it easier for engineers and developers to integrate. The VXR125-27000S achieves a remarkable efficiency rate of up to 89%, surpassing similar products in the market, and offers enhanced transient response abilities, thanks to its regulated isolation stage framework.

Reliability in Extreme Conditions

In terms of reliability, the VXR125-27000S impresses by maintaining operational effectiveness at temperatures of up to +105 °C while delivering full power without any derating across the entire input voltage spectrum. Each unit undergoes a stringent 96-hour burn-in test at elevated temperatures during the screening process, assuring users of long-lasting performance, particularly in mission-critical systems. Doug Sterk, an advising engineer at VPT, highlighted this product's introduction, stating, "Adding a 270 V input option expands the versatility of the VXR family and reflects our ongoing commitment to deliver rugged, high-performance power solutions optimized for critical systems."

Compliance and Military Standards

The VXR125-27000S has received qualifications to essential standards such as JESD22, MIL-STD-810, and MIL-STD-883, which deal with shock, vibration, and temperature cycling. Furthermore, it adheres to RTCA/DO-160 Section 16, and when paired with the compatible VXRF2-270 EMI filter, also meets MIL-STD-461, along with RTCA/DO-160 Sections 18 and 21, establishing its suitability for both military and commercial aircraft applications.

Cost-Efficient Solution

By obviating the need for external components while ensuring robust environmental performance, the VXR125-27000S effectively reduces system costs, mitigates design risks, and enhances long-term reliability. It is currently available for purchase through VPT's U.S. e-commerce platform, with plans for international distribution in the works.
