The DC/DC converters accept a 24 VDC nominal input (18 to 36 VDC) and power devices with a 72 VDC, 300 Watts output. Isolation and reverse polarity protection are provided. The 24 VDC to 72 VDC converters were created as a rugged power step-up solution for harsh applications with machine battery power, such as off-highway and oilfield equipment, power generator set control systems, and telecom. The converters are designed to meet the requirements of SAE J1455 and SAE J1113, have CE markings, and feature an IP67 rated enclosure.
