If it is the power connection of the unit door access control system, the following are common situations: 1. ** When connecting to the power supply for access control ** - For power supply locking (such as electromagnetic locks that are locked by power supply): the positive pole of the lock (usually corresponding to the electric lock's NPC terminal) is connected to the NPC of the access control power supply, and the negative pole (Ground) of the lock is connected to the Ground of the access control power supply. - For power supply unlocking (such as clutch and other power-up door opening types): connect the NO and GND of the access control power supply. - The access control power supply provides 12V power to the access control machine. The 12V of the access control power supply is connected to the power supply end of the access control machine (such as the 12V + end). The GND of the access control power supply is connected to the GND end of the access control machine. - The PUSH terminal (door opening signal) on the access control host is connected to the PUSH terminal of the access control power supply. If you want to connect the door opening button, the two wires of the door opening button can be connected to the push terminal and the GND terminal of the access control power supply. - If there is a fire protection demand, the fire protection line is usually connected to the C + and C -terminal of the access control power supply (when there is a voltage input of 5 - 36 volts, the lock will open). 2. ** When directly switching on and off the power supply ** - If the 12V switching power supply is used to directly supply power to the electric lock (such as the connection method of the rental house integrated lock), the 12V power supply can be directly connected to the electric lock 12V +, gnd. - If it was the mute lock connection method, the power supply 12V + was connected to the 12V + on the electric lock plate, and the negative pole was connected to the corresponding one. The electric lock K +, K -, K+ was connected to the power supply NO terminal, and K -was connected to the power supply com terminal or gnd terminal. The corresponding signal lines need to be connected according to the requirements of the access control host, card reader, and other equipment (for example, the card reader is connected to the corresponding signal terminal of the access control host, generally connected to 12V, Ground, Data0, Data1, etc.; if you need to connect to the Internet, you also need to connect to the RS485 line or network cable, etc.).

eps power supply reverse transmission

The EPS reverse transmission technology allows excess power to be fed back to the grid when the equipment decelerates or stops. This process realized energy recovery. When applied in high-energy-consuming industrial fields (such as elevators, cranes, and other equipment that frequently started and stopped), it could significantly reduce energy consumption, reduce the overall load on the power grid, reduce mechanical wear, and extend the service life of the equipment. From the perspective of environmental protection, through the application of EPS reverse transmission technology, the production demand for additional energy was reduced, thereby indirectly reducing the amount of fossil fuel burned, helping to reduce the carbon footprint and combat climate change. It also increased the feasibility and attractiveness of regenerative energy and promoted the development of green energy. In terms of economic benefits, after a household or enterprise uses EPS reverse transmission, it can reduce the amount of electricity purchased from the grid, thereby saving electricity bills, especially for users with large power consumption. In industrial applications, it can improve the stability and reliability of the power system and reduce the power shortage caused by sudden power demand peaks. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
