Diode Modules

Power diodes conduct electric current in one direction while preventing current from flowing in the opposite direction. Power diodes have a higher forward current carrying capacity than smaller signal diodes used in consumer electronics, making them better suited for applications where larger currents and higher voltages are involved. Power diodes are rated according to the maximum current they can carry in the forward direction and maximum reverse voltage they can withstand. When the maximum reverse voltage has been exceeded, the power diode breaks down and ceases functioning.
Diode modules decouple power supplies that are operated in parallel. Redundant power supply systems consist of two or more identical power supplies connected in parallel to the attached electrical load. The power supplies are decoupled (prevented from carrying current at the same time) with redundancy modules on each power supply. Diode modules continuously monitor the power supplies, detect any power supply faults and immediately bypass the faulty unit and shift to using the other power supply. This ensures absolute security of supply, both at the output of one of the power supply units and in the supply line from the power supply unit to the diode module.
