[Avionics Today 08-01-2016] Power conversion company VPT has introduced its VHR series of industrial-level DC-DC converters and Electromagnetic Interference (EMI) filters for power electronics applications in non-flight-critical programs in avionics, military and unmanned systems. Available in models ranging from five to 100 Watts, the VHR series of DC-DC converters offers a wide input voltage range for nominal 28 volt input, an average 85 percent efficiency, and low input and output ripple.
Designed to operate at full-load in temperatures of minus 40 to 212 degrees Fahrenheit, the VHR series also offers fixed frequency operation, soft-start, magnetic feedback, inhibit, and current-limit protection. Additionally, the VHR series includes companion EMI filters ranging from 1 to 20 amps.
