The YR20.242 redundancy module from PULS offers a robust solution for building redundant DC power systems in industrial and control applications. It features two independent input channels, each decoupled by efficient MOSFET circuitry (instead of diodes), minimizing heat generation and voltage drop while maximizing reliability. With a nominal output current of 20 A (and overload/short-circuit capacity up to 26 A), the module supports smooth switching between power sources — ensuring uninterrupted power supply even if one input source fails.
