The DC One unit is an interlocking, programmable, single-channel DC power supply that can be powered by either a battery or an AC/DC adapter. The DC One unit is an ideal power source for developer or hobbyist projects such as Arduino or Raspberry Pi powered devices. The DC One is designed to provide highly efficient operation, even with higher load current requirements.
