VPT expands VXR Series with new 270 V input DC-DC converter

VPT, Inc., a HEICO company announces the release of the VXR125-27000S, the first 270 V input model in its VXR Series of high-reliability COTS DC-DC converters, introduced in parallel with the VXRF2-270 EMI filter. The new converter delivers 125 W of output power and operates over a 160 V to 400 V input range.

The VXR125-27000S incorporates VPT's patented epoxy-encapsulated V-SHIELD packaging, designed for high chemical and environmental resistance, and features dual-sided conduction cooling to simplify thermal management. A six-sided metalized shield improves EMI performance, and the device is fully compatible with high-volume assembly processes including wave soldering and aqueous wash.

Engineered for streamlined system design, the VXR125-27000S requires no external components for stability, reducing overall part count and design complexity. The converter also delivers up to 89% efficiency, higher full-load efficiency than comparable solutions, and improved transient response enabled by VPT's regulated isolation stage design.

This new product can operate at +105 °C at full power with no derating across the entire input voltage range, ensuring consistent performance in demanding thermal environments. As part of VPT's screening process, each unit undergoes a 96-hour burn-in at +105 °C, providing added assurance of long-term reliability in mission-critical applications.

"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," said Doug Sterk, Advising Engineer.

The converter is qualified to JESD22, MIL-STD-810, and MIL-STD-883 standards for shock, vibration, and temperature cycling. It meets RTCA/DO-160 Section 16 requirements, and when paired with an appropriate VXRF2-270 EMI filter, also complies with MIL-STD-461, RTCA/DO-160 Sections 18 and 21, providing a solution suitable for both military and commercial aircraft.

By eliminating the need for external components while maintaining rugged environmental performance, the VXR125-27000S helps reduce system cost, minimize design risk, and improve long-term reliability.

The new VXR125-27000S is now available for purchase through VPT's U.S. e-commerce platform, with international availability to follow.
