Venus Express, Powered by VPT, Taking Measurements During Historic Transit

June 6, 2012 – It is getting cosmic around here! VPT is powering systems on ESA’s Venus Express, launched in 2005. Yesterday and today this spacecraft was busy taking measurements during the transit of Venus across the Sun.

According to the Venus Express blog, the spacecraft orbiting Venus is measuring sunlight as it filters through Venus’ atmosphere, revealing the concentration of different gas molecules at different altitudes. Simultaneous ground-based measurements will be compared with Venus Express data to test techniques use to characterize rocky Earth-size planets.

SpaceX Falcon 9, Dragon Mission Reaches ISS Successfully with Power by VPT

May 29, 2012 – Last week  Space Exploration Technologies (SpaceX) successfully launched its Falcon 9 rocket carrying a Dragon spacecraft bound for the International Space Station (ISS). After orbiting, the Dragon capsule successfully attached to the ISS to deliver food and supplies to the astronauts stationed there.

Space Exploration Technologies (SpaceX) made history when its Dragon spacecraft became the first commercial vehicle in history to successfully attach to the International Space Station.  Previously only four governments  – the United States, Russia, Japan and the European Space Agency  – had achieved this challenging technical feat.

VPT is proud to be a part of the excitement, powering a variety of environmental, antenna, and safety controls on board both the Falcon 9 rocket and the Dragon space capsule.

VPT Adds 15 Amp Point of Load DC-DC Converter to Space Family of Power Conversion Products

VPT is the only manufacturer to now offer two point of load converters that are MIL-PRF-38534 Class H and Class K Qualified, 100K rad hard, and available off-the-shelf.

BLACKSBURG, VA, May 8, 2012 – VPT Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI), announced today the availability
of a new point of load power converter designed and manufactured for use in the extreme environment of space. The new SVGA0515 Series point of load DC-DC converter is now qualified to MIL-PRF-38534 Class H and Class K by the Defense Logistics Agency.  The SVGA delivers up to 50W of output power, is radiation hardened to 100 krads (Si) including Enhanced Low Dose Rate Sensitivity (ELDRS), and is characterized to SEE of 85 MeV-cm2/mg.

The SVGA Series is the latest addition to VPT’s existing line of space DC-DC converters. The SVGA functions as a non-isolated,
regulated buck converter that steps down the voltage at the point of use in a distributed power system. From a single, small size, high current package, this module saves significant board space, weight, and cost for power systems headed for LEO, MEO, GEO, and deep space missions.

“To reduce weight and component cost, distributed power systems are relying more on smaller, less expensive point of load
converters used in conjunction with the larger, traditional, isolated DC-DC converters. Customer response to our space-qualified, off-the-shelf, point of load DC-DC converters has been phenomenal,” explained Monty Pyle, Executive Director of Sales. “We’ve been asked for a higher current option without the need to waste space and weight stringing together multiple POL converters.
We’re proud to announce that this product will satisfy the needs of space customers requiring higher power levels and stringent radiation requirements.”

VPT Featured In Article on Power Design Trends

February 21, 2012 - VPT was featured in Military & Aerospace Electronic’s article “Power Supply Manufacturers Pursue Smaller Size, Lower Weight, and Higher Efficiency.”

Excerpt:

“Military and avionics customers are continually seeking smaller size, lower weight, and higher efficiency in their power supplies to save on board space, design cost, and operation cost,” says Steve Butler, Vice President of Engineering at VPT Inc. in Blacksburg, VA. Not only are power supplies being weighed against those factors, but as a vital piece of any system they must be rugged and reliable.

Military and avionics power supplies also are held to high standards. “Customers also continue to demand a true military/avionics-grade, or high-reliability power converter,” Butler continues. “Hermeticity is vital for these types of applications.” Hermeticity prevents air and gas from interfering with the power supply, and many high-reliability applications such as aircraft benefit from a system that is unaffected by outside sources.
