The linear power supply structure is generally composed of: AC power input → power transformer → rectifier circuit → filter circuit → voltage regulator circuit → DC power output.

The DC power supply system mainly consists of two parts, a battery cabinet (battery screen) and a DC screen (DC charging screen). Among them, the DC panel is a high-frequency switching power supply module, control unit, step-down silicon chain measurement module, switching module, insulation detection module, battery test module and a plurality of AC input, DC voltage display, power display and other distribution units.

Generally speaking, the DC power supply in the automated test system has two output modes of constant voltage and constant current. Under certain voltage and current parameters, the power supply will work in constant voltage or constant current mode according to the load

Magnetic material is the main material of DC switching transformer. The magnetic material used in switching transformers is soft ferrite, which can be divided into two categories according to its composition and applicable frequency: MnZn and NiZn.

Voltage regulation coefficient and voltage adjustment rate: The voltage regulation coefficient refers to the relative change of the output voltage caused by the relative change of the input voltage under the condition that the load current and the ambient temperature are unchanged.

The hydrogen fuel reactor system test is mainly to test the working condition of the reactor system under different conditions, collect hydrogen, air, current value, pressure and other related data generated by the reactor, calculate the power and efficiency under different states, so as to calculate the control situation of the reactor system integrated into the vehicle and under different road conditions.

Continuous power supply to the electrolytic cell to produce pure water. During the test, Wanruida RU-18-3650 DC power supply is used for testing, setting voltage 24V, current 30A or 50A output; Set the power supply to CC constant current output mode for a long time test

Due to the continuous development of DC regulated power supply, the current DC regulated power supply is widely used in national defense, scientific research, universities, laboratories, industrial and mining enterprises, electrolysis, electroplating and charging equipment. However, with the increase of the use of regulated DC power supply, its type will also increase, then, what types of regulated DC power supply?

A transformer used as a power source for a rectifier device is called a rectifier transformer. Most of the rectifier DC power used in industry is obtained by the rectifier equipment composed of rectifier transformers and rectifiers in the AC power network. In today's highly modernized world, its great use can be seen directly or indirectly in almost every field

Dc motor refers to a rotary motor that can convert direct current energy into mechanical energy (DC motor) or convert mechanical energy into direct current energy (DC generator). Such as DC brushless motor, drone motor, electric tool motor and so on. When the DC motor leaves the factory, the body test will be carried out.

With the development of electronic technology, especially the development of digital technology, DC regulated power supply is becoming more and more important, and close to our actual life.

In the past, we know that the dispute between AC power and DC power can be said to be a key event in the history of power development, then what is the use of direct current and alternating current today?

High power DC power supply has the advantages of high power, small size, light weight and fast response, it is very widely used, but in the actual use of the process will also appear some problems, the following to introduce it in the use of several problems and corresponding solutions.

A lot of measurement work is to use programmable DC power supply to supply power to the tested part to complete the entire test process. When measuring at the set voltage point, we want the supply voltage to be very stable and accurate. But in fact, there will be some factors that cause the instability of the supply voltage. This includes the load effect and source effect of the power supply.

Compared with HVDC power transmission, HVDC power transmission is gradually showing its position, so what are its advantages

With the acceleration of the conversion of old and new kinetic energy in China, more and more high-tech new technologies are applied to industrial production, and the application of high-precision DC power supply is one of them. Compared with ordinary DC power supplies, the upgraded products can be better applied to new industries. It can provide higher speed and more stable power support during use, providing continuous power for more demanding production. So, what are the advantages of high-precision DC power supplies?

A switch is a network device used to forward electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes of the access switch. Generally, the aging time is 8 hours. Test whether the switch can work normally for a long time and check the performance stability of the switch.

With the development of power technology and the improvement of product application requirements, power supply power is also constantly improving, high-power DC power supply used for testing there are two main types, one is a linear DC power supply, the other is a high-frequency DC power supply.

The steering column is the component of the steering system that connects the steering wheel and the steering gear. Through the steering column, the driver transmits the torque to the steering device, which drives the steering device to achieve steering. Common steering columns include hydraulic steering column, electrically controlled hydraulic steering column and electric steering column. Different steering column systems are different. Then the steering column module is mainly the name of the entire system that controls the direction.

With the rapid growth of mobile communication demand, the use of battery-powered wireless communication equipment is also increasing rapidly. From the early smart phones, to the rapid expansion of the Internet of Things, drones and wearable devices, a large number of batteries are used for power to meet people's needs for small size and portability.
