I、How many sets of resistors can a controller for an LED electronic light box white light have?
If the red is connected to a 3K resistor, there will be about 86-95 pcs along the way.
If the blue is connected to a 3K resistor, there will be about 51-55 pcs along the way.
If the green is connected to a 3K resistor, There were about 56-60 along the way.
The controller refers to a master device that changes the wiring of the main circuit or control circuit in a pre determined sequence and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse direction of the motor. Composed of program counter, instruction register, instruction decoder, timing generator and operation controller, it is the "decision-making mechanism" that issues commands, that is, it completes the coordination and command of the operation of the entire computer system.
Principle:
Electromagnetic chuck controller: After the AC voltage 380V is stepped down by the transformer, it is rectified by the rectifier and becomes 110V DC, and then enters the sucker through the control device. At this time, the sucker is magnetized and demagnetized. When the reverse voltage line is connected, the controller achieves the demagnetization function.
Access control controller: The access control controller works in two modes. One is the inspection mode and the other is the recognition mode. In the inspection mode, the controller continuously sends query codes to the card reader and receives reply commands from the card reader. This mode will remain until the card reader senses the card. When the card reader senses the card, the card reader generates different replies to the controller's inspection command. In this reply command, the card reader transmits the read internal code data of the proximity card to the access control controller, allowing access control. The controller enters identification mode. In the recognition mode of the access control controller, the access control controller analyzes the code inside the proximity card, compares it with the card data stored in the device, and implements follow-up actions. After the access control controller completes the action of receiving data, it will send a command to reply to the card reader to restore the card reader status. At the same time, the access control controller returns to the inspection mode.
