Weak generally refers to the DC circuit or the audio, video lines, network lines, telephone lines, a DC voltage is typically less than 32V. Household electrical signal input of phone, computer, television set (cable TV lines), audio equipment (the output of the line), and other appliances are weak electrical equipment. Electric and electronic Conceptually, generally easy to distinguish, the main difference is the different purposes. Strong electricity is used as a power and energy, weak for information transfer. They generally have the following differences: (1) the exchange of different frequencies (2) different transmission mode (3) power, voltage and current size of the different buildings of the weak main two categories: one is the state of security and control voltage voltage Low-voltage electricity, AC and DC points, such as 24V DC control power supply, or emergency lighting standby power. The other is carrying voice, video, data and other information sources of information, such as information telephone, television, computers. Building weak in the narrow sense, mainly refers to: security (monitoring, perimeter alarm, parking), fire (electrical parts), floor control, and network cabling and audio systems Contact: 13976640562 Miss Zhang Company Name: Hainan Liansheng Science and Technology Development Co., Ltd.
