► Hardware
The MCE can be equipped with a 24V DC-in or 48V DC-in switching supply designed for use in balloon-based experiments. This unit contains a set of Vicor DC-DC converters that are trimmed to accommodate losses from cables of up to 2-metres, so they can be located up to 2-m away from the actual MCE subrack.
