The led controller for facade lighting. The controller refers to the main device that changes the wiring of the main circuit or the control circuit in a predetermined order and changes the resistance value in the circuit to control the starting, speed regulation, braking and reversal of the motor.
It consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. It is the "decision-making body" that issues commands, that is, completes the coordination and direct operation of the entire computer system.
Low voltage LED product controller:
Low-voltage LED products generally have a design voltage of 12V-36V, and the number of LEDs in each loop is 3-6 series. The resistors are used to limit the current, and the current of each loop is less than 20mA. An LED product consists of multiple loop LEDs.
The advantage is low voltage, simple structure and easy design. The disadvantage is that the current is large when the product scale is large, and a low-voltage switching power supply needs to be configured. Due to the shortcomings of the products, low voltage is not possible to transmit electricity over long distances, and is limited to products with small volume, such as signature characters and small patterns.
According to this feature, the controller design specification: 12V selects 75A/30V MOS power tube control, the output current is 8A/channel; 24-36V selects 60A/50V MOS power tube control, and the output current is 5A/way. The user can select the number of controllers according to the above specifications. The jumper can be purchased with NE20 low voltage series and gradual optional NE10 low voltage series controller. Note that the LED must be a common (+) pole connection method, the controller controls the cathode (-) pole, and the controller does not include a low voltage power supply.
There are many kinds of led controller, which we need learn more about is the led controller for facade lighting project. In this facade lighting area, we can help with control the led product , so that can many great effect or animation.
