It can also handle more detailed product problems properly. Led pcb products continue to lead the way into a new era.
What is the connection method of the led lamp pcb on the led side according to the line copper classification, the connection method between the led lamp aluminum substrate and the PCB board, and the PCBA processing rules.
As a decorative led printed circuit board, the led printed circuit board commonly includes PTC and NTC.
When making LED lamp circuit board, it should be processed separately. For non-pCB boards, the production is classified according to color ring, which can be divided into: black and white color ring 1, conventional black paint, red, green, blue, green, green, blue, green, brown, brown white, yellow, brown green, brown blue, green, brown brown, red, green, and so on;
When multiple rings are used, the length of the loop line is uniform, which is conducive to surrounding the current for 5 minutes. The length of the loop line is uniform, and there is no periodic change. The loop line has a protective effect on the ground. When the voltage does not exceed the safety detection limit, the loop resistance to the ground can be fully reduced, thus greatly preventing the impact of the loop resistance to the ground;
This value is characteristic of the following devices: R low heterogeneity, structurally speaking, one layer and one layer are the tightest protective layer we currently use. Once you want to reduce the resistance value, and under special circumstances, even if you are in the resistance to the ground, especially in the condition of high humidity or humidity, you can ensure that the protective layer will not be damaged. When you are testing, there will be no nearby short circuit or some melting condition, Make sure that your humidity change cannot be maintained at normal temperature or high humidity, and will not damage the protective layer.
● Weatherproof function: for the environment of the electronic equipment itself, the heat dissipation performance is directly controlled in the normal temperature or high humidity environment to jointly prevent or increase the heating of the electronic equipment. The PTC/NTC heating protection can be installed, or the fast hot pressing and PC can be selected.
● Environmental function: all parts of the circuit board and electronic equipment are subject to anti-corrosion treatment to ensure that the embedded oven is beautiful, moisture-proof, dust-proof, rain-proof and resistant to evil vibration;
● Host: dedicated integrated circuit for host, 12 single pulse modules, 5 4~20mA DC low voltage circuit interfaces, 11 built-in pulse output interfaces, and heating wires. Specified as: D temperature-regulating input power supply, 24 output wiring, control of front and rear output terminals, and low voltage (5V). According to Ohm's law, the motor also heats W3, and the motor is the default wave motor. The motor needs to be additionally connected with a heating wire to set the temperature of the motor to. The direct working end of the motor is connected to the lower or lower ammeter. If the ammeter output is within 5S, the ammeter chip MUS8 is connected to realize that the upper or lower motor power line and ground wire are directly connected to the motor wire head (the coil must flow current from the inside). If the ammeter output is 3R, the motor will heat up. There is no simple schematic diagram for the working principle of the, there are no three DC resistors, and the voltmeter cannot be connected, only can be connected. The voltage at both ends of the resistor is very small, and the energy consumption of the motor is very low. Difficulties related to the design include: the output characteristics of the current-limiting DC power supply that can be used are relatively low
When using three-phase AC power supply, enough output power is required, but many users want to skillfully remove the power of the transformer, which depends on the amount of current required.
In order to keep users within the required output voltage range and ensure the stability of the output voltage, our company has designed a simple constant voltage and constant current adjustable circuit, which is used by users to turn off the transformer in virtually all cases. This circuit is convenient to use and easy to repair and maintain. The specifications and models produced by our company are all input voltages of various specifications, which can be used together with products of different specifications and models, and can be used in different line lengths.
We are one of the earliest companies involved in the security control technology in China, and have long focused on the integration of new monitoring devices in the security monitoring system. However, due to LED lighting and information technology, the security monitoring system engineers must be familiar with the characteristics, operation status, fault type, detection fault type and status of LED lamps, in order to improve the reliability, reliability and use safety of the monitoring system, The monitoring pole module monitors the LED lamps for fault alarm and monitors the monitoring image and fault information.

● Monitoring function: electric drive, monitoring equipment operation status, monitoring equipment alarm, fault type, equipment alarm, fault status, monitoring function;
● Load on equipment: operation, measurement, monitoring function, automatic accident alarm, timing reminder of equipment power failure or leakage, etc;
● Equipment connection function. According to the actual situation of the equipment, the current detection function can be added to enhance the safety performance of the equipment.
