More professional equipment needs multi-channel adjustable power supply to provide power, which is a power supply that can achieve different effects through a power supply, then the price of this power supply is expensive? Is it useful?

It has to be said that DC power supply is one of the great inventions in human history, its application is too wide, involving all aspects of people's lives, almost all electronic devices are inseparable from its application!

The use of DC power is used in a lot of equipment, because it is different from the AC power in our family life, so it is relatively simple to use, but the demand for power also makes DC power have a lot of types and specifications, but also need to use DC power according to different needs. For example, the application of adjustable DC power supply is more extensive, then what are the specific applications? Are there any techniques for using it?

At the thought of the use of power, people are worried about the risk of use, especially in our daily life, the use of power must ensure safety, otherwise the accident is a big accident, no one can bear the responsibility. During the operation of the equipment, it also needs power supply, such as the operation of the car requires DC power supply, and the operation of some large equipment requires its own high-voltage DC power supply, so is the operation of this power supply dangerous?

In today's society, the application of DC power is more and more extensive, perhaps in daily life we may not see it often, but it plays a huge role in other areas. So, what is DC power?

With the rapid development of the automobile industry and the development and construction of expressways, the speed of automobiles is getting faster and faster, and the accidents are more frequent, so the safety of automobiles becomes particularly important.

In order to measure large DC currents, such as tens or even hundreds of amps, no ammeter of this size can be used for current measurement. What should be done?

In the future, with the continuous layout of hydrogen refueling stations, the continuous decline of the cost of fuel cell systems and the breakthrough of low-cost hydrogen production technology, the performance, reliability, life and other parameters of fuel cell vehicles will soon be comparable to the level of traditional fuel vehicles.

In some areas, there are 2 transformers in the substation, but the two transformers are distributed by a section of the bus, using a single bus or a single bus section connection mode, which can not be treated as a double power supply. Therefore, the dual power supply should be a power supply that is introduced from the electric power substation and consists of a power supply composed of different bus segments.

Double power supply and double circuit power supply, people generally think that is the same thing, mixed with each other. But I think there are some differences. Dual power supply is of course introduced from two power supplies (different in nature), and the feed line is of course two; If it refers to the power supply, it is a dual power supply.

Speaking of electricity, it is widely used in our life. Without electricity, our life would be chaotic. We currently can't play games, watch TV or eat without electricity. However, although electricity is convenient for our life, it also has security problems.

During the test of the turbopump, the power supply mainly provides the initial electric energy of the starting motor. After the turbopump is rotated, the starting motor switches to the measured state and becomes the generator. At this time, a resistance box is configured for continuous loading test.

At present, energy shortage, environmental pollution and climate warming are the common challenges facing the global automobile industry. Governments and the industry have put forward their own development strategies and actively respond to them in order to maintain the sustainable development of the automobile industry and improve the international competitiveness in the future. New energy vehicles have become a hot spot in the development of the automobile industry now and in the future.

High voltage DC power supply, usually refers to the output voltage of more than 5000 volts of power supply, generally the output voltage of high voltage DC power supply can reach tens of thousands of volts or even hundreds of thousands of volts or even higher.

In today's society, with the continuous progress of science and technology, more and more modern medical devices have been rapidly developed, medical power and other power supplies in the mass market and consumer electronics and other low-cost product applications are different from most power supplies

The key ways of heat dissipation of heat pipe radiators are radiation source and heat convection.

In recent years, with the rapid development of power electronics technology, some DC electrical equipment for DC power system requirements are becoming higher and higher, not only the output current is large, but also the voltage ripple, voltage regulation accuracy, overload capacity, efficiency and other indicators are also very high requirements, therefore, the study of large capacity, high-performance DC power system is necessary.

According to the division of function of the circuit, the control circuit can be divided into several parts: pulse generation circuit, trigger circuit, voltage feedback control circuit, soft start circuit, protection circuit, auxiliary power circuit, etc

In the hard switching PWM circuit, the switching tube works in the hard switching state, the switching device is on at high voltage and off at high current, so there must be a lot of loss at the switching moment. Therefore, buffer circuits, such as Rc absorption networks, are often added. It can limit du/dt when on and di/dt when off, so that the power device can operate safely and normally.

When testing the air conditioning compressor of electric vehicles, first choose [Wanrueda RU smart DC power supply], set the power supply to work in cv state, by adjusting the rated voltage ±10-15%V, test the performance of the compressor for how long it can withstand. Simulate the electric vehicle battery pack at full capacity and low power to test the compressor performance.
