With the development of miniaturization and decentralization of communication products, especially data products, and decentralized power supply of communicationWith the wide use of embedded power supply, the market of embedded power supply is expanding rapidly, especially in recent yearsFor example...【READ MORE】

5g base station is composed of BBU and AAU. One base station is configured with one operator's three cells (1 BBU + 3 AAU). Assuming that the power consumption of 5g BBU is 350W and that of AAU is 1100W, relevant power matching calculation is carried out.1. battery capacity estimationThe calcula...【READ MORE】

The circuit completes the function of inverter by turning on and off the power electronic switch.characteristic:(1) High efficien...【READ MORE】

The issuance of the 5G license means that we have a pass in the 5G era. Undoubtedly, the change of 5G to our lives will be trans-temporal.Let me give you a few examples that are closely related to everyday life.1 After entering the 5G era, most of the large-scale games (as for applications) are not ...【READ MORE】

Why choose - 48V as the supply voltage instead of + 48V?   1. Voltage is relatively safe, for example, human body is 50K ohmic resistance, voltage-48V, 48/50000 = 0.00096A = 0.96mA, human body flow through 9mA will be life-threatening.   2. The inheritance of history. N yea...【READ MORE】

Maintenance and Maintenance of Lead-acid Batteries   1. The discharge depth of lead-acid batteries has a great influence on the cycle life of batteries. This is because the deeper the discharge depth is, the larger the expansion and contraction of the electrodes are, the more the active ...【READ MORE】
