New SMD. VPT's DVPL point-of-load converter is first of its kind to earn DSCC SMD.

The Defense Supply Center Columbus (DSCC) has issued the world's first Standard Microcircuit Drawing (SMD) for VPT's DVPL0505S point-of-load DC-DC converter. 

This is a non-isolated, synchronous, buck regulated converter that steps down the voltage at the point of end use. The DVPL is the only point-of-load converter designed and built to military-grade reliability as defined in MIL-PRF-38534.

This designation simplifies the procurement of high reliability power management products for Department of Defense (DoD) programs specifying avionics, military, and space qualified components.

VPT Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI) and the innovative leader in providing power handling products for avionics and other high reliability applications, today introduced a new DC-DC converter module: the VPT100+ 2800 Series. With up to 100W of output power per unit, this new commercial-off-the-shelf (COTS) converter offers parallel operation of up to five units to enable the fast, easy, affordable creation of high power systems.  

VPT Inc., a HEICO company, recently made an NT$320,000 donation for the victims of the devastating Typhoon Morakot that hit Taiwan in August. Dr. Dan Sable, VPT President stated, "There is a great deal of concern by our team members for those affected by this tragedy. It is our hope that this donation goes directly to the families and victims that need the help the most as they rebuild thier lives." 

VPT Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI) and the innovative leader in providing power handling products for avionics and other high reliability applications, has introduced a new bus converter module: the VPTHVM-270 Series. With up to 200W of output power, this regulated bus converter module operates from a 270V bus to step down the power to create a regulated 28V bus for avionics power systems. 
 

“With this new module, engineers can create a 28V bus to run many of the avionics subsystems, such as electronic warfare or other instrumentation,” explained Michael J. Bosmann, Senior Vice President of Sales and Marketing for VPT. “The new VPTHVM-270 serves as the cornerstone for a distributed power system, powering multiple VPT DC-DC converters from a single module.”

MIAMI and BLACKSBURG, Va., May 4, 2009 -- HEICO Corporation (NYSE:HEI.A) (NYSE:HEI) today announced that its Electronic Technologies Group has acquired 82.5% of VPT, Inc. ("VPT"). Financial terms were not disclosed.

HEICO stated that VPT's existing management will remain with VPT under employment and non-competition agreements. Further, HEICO stated that it does not expect any material VPT staff turnover following the transaction. The 17.5% of VPT that HEICO did not acquire will continue to be owned by an existing shareholder which is also a supplier to VPT.

VPT's President and Co-Founder, Dr. Daniel M. Sable, remarked, "We are excited to become part of HEICO. Being acquired by HEICO allows us to partner with a very successful company that can provide resources for VPT's continued growth and which understands how to foster growth in companies like ours."

ITT Corporation’s Space Systems Division recently awarded VPT its prestigious annual Supplier Excellence Award for work done on the GPS IIR-M and GPS III programs.

Lance Eurysal, Director, ITT Corporation, Space Systems Division Supply Chain remarked at the award ceremony “VPT has been involved with ITT’s GPS programs since 2003. They started by delivering flight hardware for the GPS IIR-M program. They delivered flight hardware for eight satellites in nine months. So far six satellites have been launched and all of their hardware is working as expected.

“For the GPS III program, VPT was the first subcontractor to hold a process design review (PDR), five months after receipt of order. This PDR received high marks from both ITT and the end customer.  Engineering design models were delivered on schedule in seven months time.

“VPT’s performance was first recognized immediately after the launching of the first GPS IIR(M)-14 in September 2005 and ITT has annually acknowledged their professional diligence and technical expertise since then.”

Dr. Dan Sable, President of VPT, accepted the award.

Dr. Dan Sable, President of VPT, will give a presentation at this event entitled “VPT TOR-compliant Hybrid DC-DC Converters."

Presentation Synopsis: The presentation discusses designing and manufacturing hybrid DC-DC Converters compliant to the Aerospace Corp. Technical Operating Report (TOR), which potentially will govern most new critical US Government Satellite programs. The TOR goes well beyond Mil PRF 38534 Class K element evaluation and radiation characterization. The talk will discuss the performance, reliability, and cost impacts of the TOR on hybrid DC-DC Converters.

Space Parts Working Group (SPWG) is a joint government-industry working group sponsored by The Aerospace Corporation and the Space and Missile Systems Center. In its 38th year, SPWG is an unclassified, international forum for disseminating information to the aerospace industry and for resolving problems with high-reliability electronic piece parts for space applications.

New EMI Filter/Transient Suppression Module. Introducing the new VPTi10-28 Series.

The new VPTi10-28 combines two modules in one mini package to reduce the reflected noise of DC-DC converters and, simultaneously, protect the power system from inrush current damage. Designed to save valuable space and weight in a power system by combining multiple functions into a single module, the VPTi10-28 is suited for distributed power systems in avionics and military applications.

This new EMI filter and voltage transient protection module is part of VPT's COTS standard product line, the VPT Series.
