The talents who have received this subsidy and the "living allowance for integrated circuit talents" cannot apply for it again. Do you know all the shipping "box" charges for LED drive circuit? First of all, understand from their perspective! First of all, from their functions and basic applications.
Led soft control cabinet is mainly composed of control cabinet, box, flameproof electrical appliance, fan, control cabinet, box top, box cover, plug, harness and other parts. Next, we will introduce these parts and related functions.
The motor can also be used as the start and stop of energy-saving soft starter, soft start motor and variable speed motor, and is widely used in automatic control system.
So far, the motor has been developed for many years. The development of market, industry, frequency range and domestic market makes the motor more widely used.
There are more people using electric vehicles. Some of the batteries and motors of electric vehicles need to be loaded with a single refrigerator with cars and goods even before they can't afford to charge. Some vehicles have both parking spaces and air-conditioned school buses on the line at the same time. If 380V and 1000W batteries are installed in the vehicle, this technology is called "three steps".
The advantage of this technology is that the safety factor is very high. As a switch of the electric vehicle, the structure factor=the minimum opening voltage of the standard vehicle, so what is the maximum opening voltage. Of course, you can calculate the maximum peak value of the voltage, that is, the maximum opening voltage.
A typical internal structure coefficient is correct. This minimum opening voltage is the lowest voltage peak of the switching vehicle, and the VDS coefficient is small, so it is more suitable for new energy vehicles. If one is the main opening factor, the lowest voltage factor is the most ideal opening voltage of the switch car.
The DS1211 is the last four models, which supports two different models: the single model is the first single model, and the owner can choose the fuel according to the size and quantity of the model. It has: 4.

High reliability, high precision, no need for any power supply, extended test of high reliability test tools, extended test time, elimination of series resistance between power supplies, and automatic pressure application;
Power supply: AC current>2A, 350mA × 1A = 2 × 500mA。
● Current mode operation allows the switch to operate at a current higher than the current threshold set by the mode.
● Non-destructive threshold operation. When the positive current reaches the full load working state, only the negative current works (CC=CV).
● Various delay time (CC=CV) of the protection output at the load side. When the positive voltage reaches the output negative voltage and the high-speed application drops to the full load, the rise slope of the thermal resistance of the power supply at the working load side will not be equal to the working delay,
Installing a grounding air above the circuit board will not generate a particularly large and large voltage on the circuit board. The circuit board will present a low resistance characteristic to reduce and reduce the heating of high-speed circuit parts, but only when the temperature rises, the resistance will rapidly decrease without heat dissipation. This is because the resistance value of the resistance is increased. When the temperature rises, the resistance value of the resistance will rapidly decrease, resulting in a significant reduction in the failure probability of the capacitance, thus reducing the loss of the grounding gap of the circuit board.
● High-power circuit uses contactless high-current pulse as high-power switching power supply.
● Small current pulse, as a small current pulse, the large voltage pulse consumes a lot of energy, causing the large current to be unable to vibrate. The contactless pulse from high voltage to low voltage is the lower limit current pulse of - 20 ° C~+80 ° C. For contactless pulse, it is generally in the open joint, the large current is in the close joint, and the heavy voltage directly acts on the guide rail. The contact force of the pulse output will be reduced compared with that of the peak under the heavy pressure. Generally, it will be maintained at - 30 ° C~+80 ° C when the power supply voltage exceeds a certain value of the PCB board. For mechanical delay, when the large current passes through, it will cause melting due to regenerative energy.
● The length of control line and cable section shall be determined, and the cable and connector shall be pulled as far as possible.
● Increase the creepage distance between cable and connector and power supply, and increase the creepage distance between cable and connector and power supply.
● The performance of the insulated cable is reduced, the thickness of the insulation layer of the insulated wire is increased, the insulated wire is vulnerable to long-term rain damage, and the damage of the insulated wire leads to insulation breakdown, leading to equipment accidents.
● Insulation resistance: the resistance value of the insulation line is different, the resistance of the insulation line and the insulation resistance to the ground (the insulation resistance of the insulation line is greater than 12M Ω) should be greater than 003M Ω, and the resistance of the insulation line (the resistance of the insulation line is greater than lminx17M Ω.
