For historical, practical, and technical reasons, telecom systems typically utilize a -48 V DC power supply. In the event of a grid malfunction or other emergency, telecommunications networks require dependable backup power sources. Commonly used for reserve power, lead-acid batteries can also operate at -48 V DC.
Telecom power supplies with rectifier (72 kW right, or 90 kW left) and inverter (7.5 kVA) in one system as well as 10" touch display of the MCU 3000 system controller built into the cabinet door.
Voltage regulation: The power supply must provide a stable and regulated output voltage per the requirements of the telecom equipment. High efficiency: Power supplies should be highly efficient to reduce power loss and energy consumption. Efficiencies of at least 90% are typical.
In the event of a grid malfunction or other emergency, telecommunications networks require dependable backup power sources. Commonly used for reserve power, lead-acid batteries can also operate at -48 V DC. Using the same voltage for both primary and backup power makes it easier to design and maintain backup systems.
Incorporate advanced materials and technologies such as semiconductor devices made of Gallium Nitride (GaN) and Silicon Carbide (SiC) to provide increased power density, enhanced performance, and increased operating frequencies. For historical, practical, and technical reasons, telecom systems typically utilize a -48 V DC power supply.
The power supply systems thus secure the entire transmission technology (LTE, 5G, VOIP, TV, servers, etc.) against network failures. They are precisely tailored to the requirements of the telecommunications network operators. These include:
