New DC-DC converter offers wide input range and parallel operation for higher power

The GPD500 500W DC-DC converter, available from Gresham Power Electronics, has been designed for use with fixed and mobile communications and security systems on tactical and non-tactical vehicles. Sophisticated electronics developed for defence vehicles, is designed to be powered from 24/28VDC and in most cases is unable to operate from the 12VDC electrical systems found on non-tactical vehicles. Instead of making significant changes to the equipment design, this issue is solved by the new converter. These converters have a wide-range DC input voltage from 10V to 20V, feature ultra-high efficiency of typically 96% at full load and can operate over an ambient temperature range of -40C to 70C.
