Auxiliary Power Modules (APM) are connected to the DC Bus, and supply DC power to another power group's DC bus, referred to as the "Sub Power Group". APMs can be a pass through extension of the DC Bus, or a step down to a lower DC Bus voltage. Multiple APMs can be connected to create multiple Sub Power Groups, at the same or different voltage levels.

Power flow to/from the DC Bus is reduced proportionally by the APM efficiency.

APM Types
Sequence Type

APM application requirements can be defined as a Power vs Time Sequence, or directly linked to another Power Group in the project, as specified by the Sequence Type.
