VPT Introduces More Than 50 New DC-DC Converter Modules For Use In Space Power Systems

VPT Inc. has introduced more than 50 dc-dc converter modules specifically designed and manufactured for space applications. Grouped into four product families, these new space dc-dc converters deliver up to 120W of output power, and are said to operate reliably through harsh radiation environments.

"VPT is the first to provide dc-dc power conversion products with a guaranteed radiation tolerance through long-term exposure to low dose radiation, the most typical type that affects the success of the mission," explained Michael J. Bosmann, Senior Vice President of Sales and Marketing for VPT. "Years ago we were focused on a total dose of 100krad or more, but over time the industry has learned that continual low dose radiation is much more of a concern and typical of that encountered during the application. Our new product line satisfies today’s updated reliability requirements for space including the new radiation requirements, small size and light weight mandates, stringent requirements of 100% reliable operation through a wide range of space flight conditions, and fast product availability."

VPT packages its "S" space series of dc-dc converters in miniature, hermetic, metal cases for reliable power delivery through the extreme temperature, shock, vibration, and radiation environments of space travel. Specific features of the new SVSA, SVHF, SVTR and SVFL product families include: six to 120W of output power in standard single and dual output voltages; characterization and guarantee to 30krads (Si) per VPT’s RHA plan specified per MIL-PRF-38534, Appendix G, Level P with 2x margin; characterization and testing for TID (total ionizing dose) at HDR (high dose rate) and LDR (enhanced low dose rate sensitivity – ELDRS) per VPT’s RHA plan; MIL-PRF-38534 Class H element evaluated components standard; fault tolerant design with radiation immune magnetic isolation technology – no optoisolators; and a wide case temperature operation of -55 to +125°C with full performance over entire temperature range.

The new space series units are available immediately with pricing beginning at $950 for the 6W SVSA Series in OEM quantities.
