Wide Input Voltage Range and Advanced Packaging Technology for Superior Operation in Harsh Environments
The VXR Series of DC-DC Converters and EMI Filters represent VPT’s most advanced offering of its extensive line of high-reliability COTS DC-DC Converters and accessory products, and are available in the UK from APC Hi-Rel.
Models range from 7 to 100 Watts with an industry-leading wide continuous input voltage range from 9 to 60 VDC and transient operation from 6 to 80 VDC. The VXR Series is optimised for a broad range of applications from military ground vehicles to commercial and military aircraft, including the unique power needs of unmanned aerial and ground systems.
The VXR Series utilises VPT’s patent-pending advanced packaging technology. This proprietary encapsulation process incorporates EMI shielding and dual-sided thermal conduction. The integral epoxy encapsulated packaging is highly resistant to chemical, solvent and salt environments and is fully compatible with high-volume manufacturing processes including wave solder, cleaning solvents, high-pressure sprays and aqueous wash.
“The VXR Series of products is reliability and efficiency focused, utilising a low-noise, fixed frequency wide input voltage range topology,” said Jeremy Ferrell, VPT’s Manager of Standard Product Engineering. “We achieved this high efficiency over a wide input voltage range with a proprietary precision-controlled synchronous rectification topology. The high efficiency design in-turn reduces the thermal management requirements. We also incorporated a proprietary control loop design that provides a fast transient response without the use of optoisolators.” Ferrell added, “For customers with noise sensitive applications, we developed the VXR EMI Filter Series with current ratings from 2 to 20 Amps that were specifically designed to meet specific MIL-STD-461 and DO-160 conditions when used with our VXR Series DC-DC Converters.”
The VXR Series of DC-DC Converters and EMI Filters are available in the UK from APC Hi-Rel, part of APC Technology Group plc.
