Astron Step-Down DC/DC Converters
These Astron Corporation Step-Down DC/DC Converters offer high-efficiency DC conversion. These down-converters change an input voltage of 24 or 48 Vdc nominal--actually, a range of 22 Vdc to 56 Vdc or 30 Vdc to 56 Vdc, depending on the model--to a highly regulated output voltage of 13.8 Vdc. These converters provide no isolation between their input and output negative terminals and are meant for use in negative-ground systems.
Features include overvoltage and short-circuit protection, input-side overvoltage/transient protection, and input-side reverse polarity protection. Some possible applications include industrial equipment, heavy trucks, buses, marine vehicles, mobile radio equipment, and conversion from 24 volt aircraft systems.
If you have a need to convert your high-voltage DC to 13.8 volts, these Astron Corporation Step-Down DC/DC Converters from DX Engineering are designed to handle all of your most demanding applications!
