The modular architecture, efficiency, compact design and comprehensive monitoring and control features provide significant benefits over the current industry standard. The Flatpack S rectifiers have intelligent selfprotective features like reduced output power at high temperatures or low mains. The optional Flatpack S 24/1000 SIL3 OVP is targeted Safety and Automation Systems (SAS) where SIL rated overvoltage protection is required.

Flatpacks Wallbox
The Flatpack S Wallbox Marine is a complete, ready to install system. All cable entries and terminals are located at the bottom of the system for easy access and connectivity. The design allows cables to be routed behind the Wallbox. AC input and signaling cables are connected to terminal blocks while DC output is connected directly on the MCB.
