Power supply unit with some DC-DC converters located outside the enclosure and integrated into cable harness assembly

A power supply unit (1000) with some DC-DC converters located outside the enclosure and integrated into cable harness assembly, the power supply unit (1000) comprising:

• an enclosure (100);
• a main DC voltage output rail (104);
• a first branch DC voltage output rail (114);
• a second branch DC voltage output rail (115);
• an additional DC voltage output rail (107) being incorporated within the enclosure (100);
• and
• a supervisor IC (101);
• the power supply unit (1000) is characterized in that:
• the main DC voltage output rail (104) is incorporated within the enclosure (100), the supervisor IC (101) is internal or external to the enclosure (100), the first branch DC voltage output rail (114) and the second branch DC voltage output rail (115) are located outside the enclosure (100), wherein the first branch DC voltage output rail (114) and the second branch voltage DC output rail (115) are connected back to the supervisor IC (101), the first branch DC voltage output rail (114) is coupled to the main DC voltage output rail (104) through a first DC-DC converter (111), the second branch DC voltage output rail (115) is coupled to the main DC voltage output rail (104) through a second DC-DC converter (112), wherein the first DC-DC converter (111) and the second DC-DC converter (112) are located outside the enclosure (100) via integration into a cable harness assembly (113).
