SMD aluminum electrolytic capacitor - Compact and efficient, suitable for a wide range of applications in power supplies and filtering circuits.
For ease of installation, operation, and maintenance, the wiring between all equipment in the electrical secondary circuit is labeled, which is known as the secondary circuit number. These labels typically use numbers or a combination of numbers and words to indicate the function and purpose of each loop. This labeling system helps technicians quickly identify and troubleshoot issues during maintenance or upgrades.
The basic principle behind circuit labeling is that all devices should be connected through terminal blocks using control cables. Devices installed on the top of the panel or within the cabinet also need to connect via terminal rows. In such cases, the top-mounted devices are treated as off-panel components, and their connections follow the same loop numbering principle. Each connection is clearly marked, making it easier to trace and manage the wiring.
To ensure clarity, different reference methods are used for DC and AC loops. In both types of circuits, distinct numbers are assigned to individual loops, allowing engineers and technicians to quickly determine the nature of each circuit when reviewing wiring diagrams. This systematic approach greatly improves efficiency during installation, troubleshooting, and future modifications.
2V Lead Acid Battery
First, basic concepts
AGM battery, the full name of Absorbent Glass Mat battery, that is, adsorbed glass fiber separator battery, is an innovative lead-acid battery. It uses a special glass fiber separator, which can effectively adsorb and fix the electrolyte, so as to achieve efficient and balanced charging and discharging of the battery.
​Second, technical characteristics
Efficient charging and discharging: Thanks to the special glass fiber separator, AGM batteries ensure that the electrolyte is evenly distributed inside the battery, thus improving the charging and discharging efficiency of the battery.
Sealed design: Most AGM batteries have a sealed design that eliminates the need for open exhaust, but instead regulates the internal and external air pressure through a pressure control valve. This design not only avoids the emission of acid mist, but also makes the battery more heat-resistant and reduces the performance degradation caused by excessive water loss.
Strong durability: The cycle charging capacity of AGM batteries is high, usually able to reach about 3 times that of lead-calcium batteries, so its service life is longer. At the same time, its capacitance also shows high stability during the whole service cycle.
Low temperature start reliable: The AGM battery in low temperature environment starting performance is more reliable, to ensure the normal use of the vehicle in cold weather.
Environmental protection: The design of the AGM battery reduces the emission of acid fog and pollution to the environment, which is in line with the modern environmental protection concept.
3. Application scenarios
Due to its superior performance characteristics, 2V AGM batteries are widely used in a variety of scenarios that require high-reliability and long-life batteries. For example, it can be used as a backup power supply to provide stable power support for key facilities such as communication base stations and data centers. It can also be used as a part of the energy storage system to store and release electrical energy to meet the power needs of different time periods.
