There is a big category in the multimedia conference room, which is the central control system, which is also called the central control. In the central control, we often encounter the power controller, which is also called the strong current controller, or the strong current relay. What are the functions of the power controller? What is his principle?
The power control internal uses 8 strong current relays, supporting 30A relay module, and the power can reach 2kW per circuit. Therefore, we usually use him to control the power switch of the equipment in use, and also use the characteristics of his relay to control such as: the lifting operation of electric projection screen and the switch of bulb.
Generally, when we configure the central control system, we must configure the power controller. The power control can realize the on-site multi-channel power switch. Users only need the iPad in their hands to realize the on-site light switch, projection screen, electric curtain closing and opening operation.
Power controller plays an important role in intelligent programmable operation of central control system. He is a common peripheral equipment in the central control system. He is different from the weak current relay provided by the central control system. The strong current relay switch he adopts can directly connect to the 220V voltage, rather than the weak point low power switch equipment of 12V and 24V.
The power controller is equipped with two RS232 interfaces, and can realize ID setting by dialing code, so that it can be used in the case of cascade of multiple devices to realize intelligent control. And the convenience of operation.
