What are the characteristics of general LED drivers
Machine vision is to use machines instead of human eyes to make measurements and judgments. The general machine vision system consists of: industrial cameras, light sources, industrial computers, image analysis software, etc. Machine vision is not only to "see", it also needs to understand the information it sees, and assist mechanical systems and robots to autonomously realize related functions and actions, and finally realize intelligence.
The EPC-P3000 series of embedded industrial computers specially designed for machine vision applications are fully launched. EPC-P3066 is an embedded industrial computer specially designed for machine vision applications. It is equipped with the 9th generation IntelDesktopCPU platform and has multiple expansion slots. It can support high-performance computing and help the edge deployment of high-precision machine vision.
NU501 is a universal LED driver with simple application developed by Shuneng Company, which is suitable for various LED lamp driving applications.
The main features of the driver: single-channel, dual-channel constant current output, the output constant current is fixed. , The output range is 15------60MA (determined by the suffix of the model). The composed driver circuit does not require peripheral components, and the circuit is extremely simple. The single channel is a three-terminal device in the SOT23-3 package, and the dual channel is in the SOT23-5 package. The device is small (small PCBS board space).
Wide input voltage range: 1.5V~12V, output voltage range 0.4-17V, can use VDD terminal to input PWM signal for dimming control, current rise/fall time is fast (2US). The junction temperature range is -40~120℃. When the input voltage is high and the negative cut voltage of the LED is low, the drivers can be connected in series (only for single channel).
When multi-channel output, the output current difference of each channel is less than +-5%, and the voltage and negative cut adjustment are less than 1%, which meets the lead-free requirement. The driver is mainly used in various LED lightings composed of medium and low power LEDs and LCD backlighting, in addition. It is also suitable for applications such as flashlights and flashlights.
Packaging and pin engineering
NU501 has two packages and pinouts. Where VDD is the positive power supply. Vp is the current input terminal. VN is the current output terminal (in the case of a single NU501, this terminal is the negative terminal of the power supply).
The model number is 1AXX2AXX is the suffix of NU501. 1A means single channel, 2A means dual channel. XX represents the output current value. For example, 1A20 means single channel, the output current is 20MA, 2A18 means dual channel, the output current is 18MA.
The application scheme of machine vision, GPU graphics card, PoE network card, motion control card and data/video capture card will be universal requirements, which can be flexibly configured according to different application scenarios.
Advantech EPC-P3000 provides 4 PCI/PCIe expansion slots, as well as corresponding riser cards and Advantech iDoor modules, which can easily configure dedicated edge computers. It also provides a wealth of expansion options to integrate multiple peripheral devices.
How to efficiently and quickly assemble and configure the equipment to go online.
