The PPU 300 Hybrid (battery) controller variant controls an inverter with a power source, and the inverter breaker.

Several Hybrid controllers can be interlinked in a power management system controlled by an external PLC or similar. In such a system, the PPU 300 Hybrid controllers handle functions such as Power Take In (PTI) and Power Take Off (PTO), running on battery power only if needed and available, asymmetric load sharing with configurable constant discharge, and genset start if required.

Each Hybrid controller can control up to three non-essential load groups.

The table shows a 7-slot rack, but the controller is also available with a 4-slot rack. Modules PSM3.1, ACM3.1, and PCM3.1 are mandatory. If you add expansion module racks, each expansion rack must contain a PSM3.2 power supply module but does not need to contain other modules.

For general information about the PPU 300 controller range and its modular architecture, see the PPU 300 main page.
