The large-scale distributed intelligent power distribution system is mainly applied to large-scale weapon systems with a large number of electrical equipment such as large aircraft and ships, Mainly includes: power supply system processor（PSP）、 Electrical Load Management Center (ELMC) and solid-state power controllers and other equipment. PSP controls ELMC and SSPC through the internal bus of the electrical system.

Small and medium-sized distributed intelligent power distribution systems are mainly applied to weapon systems with relatively few electrical equipment such as large unmanned aerial vehicles, tanks, and subsystems. They mainly include electrical load management centers（Equipment such as ELMC and Solid State Power Controller (SSPC). The upper computer controls ELMC to manage the electrical load through the bus, and ELMC manages SSPC through an extended internal bus.

The centralized intelligent power distribution system is mainly applied to weapon systems with relatively few and concentrated electrical equipment such as small unmanned aerial vehicles and subsystems, using a single electrical load management center（ELMC or Solid State Power Controller (SSPC) manages electrical equipment. The upper computer controls ELMC or SSPC to manage electrical equipment through the bus.
