Due to the wide variety of integrated circuits used in communication equipment, their power supply voltages are also different. In the communication power supply system, a high-frequency DC-DC isolation module power supply with high power density is used, which is converted from the intermediate bus voltage (usually 48V DC) to Various DC voltages are required, which can greatly reduce losses, facilitate maintenance, and are very convenient to install and increase. Generally, it can be directly installed on the standard control board, and the requirement for the secondary power supply is high power density. Due to the continuous increase of communication capacity, the capacity of communication power supply will also continue to increase.

● India  small size. Because the power module is also a kind of switching Marine boost/buck voltage power supply, it uses PCB boards and components with higher integration, and with reasonable layout and design, it has a great advantage in volume, which may effectively reduce the volume of developed products.

● each module can be strictly tested separately to ensure its high reliability, including power on test, so as to eliminate unqualified products. In contrast, integrated solutions are more difficult to test because the whole Marine boost/buck voltage power supply system is closely linked with other functional systems on the circuit. Each power module has also undergone strict high-temperature testing and aging, and the product performance is stable.

● different suppliers can design modules of the same size according to existing technical standards, providing engineers who design power supplies with a variety of different options. That is, you can relatively change the stitch name, volume and shape of the product according to the characteristics of your product, so as to meet the needs of customers to a greater extent.
