The power controller refers to a master device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit according to a predetermined sequence to control the start, speed, brake, and reverse of the motor.
The power controller can be used in conjunction with the conference central control system to realize centralized intelligent control of the power supply. The power controller uses a computer and central control to control the equipment, such as equipment switches, electric screens, electric curtains, electric hanger lifting control, and projector delayed shutdown.
The power control device is easy to wire. You only need to open the small junction box shell during installation to connect and adjust the ID code(servo voltage controllers). There is no need to open the entire surface shell. The device is equipped with a wall mounting bracket, which can be placed flat or mounted on the wall! Control, open software platform, with equipment status feedback display function.
The brushless DC motor controller includes a power conversion circuit, a microcontroller, and signal input and output circuit. The controller stores the controller's working program. It can accurately control and detect the position sensor of the DC motor to effectively control the motor. Control, control for dynamic real-time monitoring, and effective protection of the motor, solving the technical problems of inaccurate control and unreliable protection.
When the No. 1 relay is the power switch of the projector, even if the short-term power failure is due to the mains power, the projector will automatically shut down, but then it can automatically restore the previous working state and continue to supply power to the projector's cooling fan! Better protection Projector.
When controlling the light switch, even if it is due to the mains power, the previous working state can be automatically restored after a short-term power failure, avoiding the trouble of not being able to turn on the light!
The power interface has normally open and normally closed terminals, which can be linked with other control modules (such as the dual-control function of lighting); the machine has a built-in 220V power supply, and no additional power supply is required.
Built-in DIP address code switch, which can be cascaded according to different system needs; built-in eight-way imported 30A high-power relay module, each power can reach 2000W; built-in two-way RS-232/485 interface, convenient for connecting multiple power controllers.
