The customer confirms the model of the product required to be purchased = We will prepare a detailed formal quotation process based on the inquiry model, price and delivery date.
The customer orders the product after receiving the quotation and confirming that the model is correct = the person in charge of the quotation drafts a sales contract based on the model and quantity provided by the customer.
After receiving the contract review and approval, the customer will stamp and return it and remit the money to the company's account bank according to the contracted sales volume.
After our company's finance department checks the payment, the salesperson arranges the shipment and notifies the customer to track the waybill.

>Technical indicators of DC power supply
>
> The technical indicators of DC power supply are divided into two types: one is the characteristic indicators including allowable input voltage, output voltage, output current and output voltage adjustment range Another quality indicator is used to measure the stability of the output DC voltage, including voltage regulation coefficient (or voltage regulation rate), output resistance (or current regulation rate), ripple voltage (surrounding and random drift) and temperature coefficient.
> Ripple voltage: The AC voltage component superimposed on the output voltage. Use an oscilloscope to observe the peak-to-peak value of a sanitary pump, which is generally on the order of millivolts. An AC millivolt meter can also be used to measure its effective value, but there is a certain error because the ripple is not a sine wave. The ripple voltage of a general DC power supply is -.
>
> Voltage regulation rate: the relative change amount of the output voltage when the relative change of the input voltage is %. Both the voltage regulation coefficient and the voltage regulation rate illustrate the impact of the input voltage change on the output voltage, so only one of them needs to be tested. Just one.
> The output resistance is the same as the output resistance of the amplifier, and its value is the absolute value of the ratio of the output voltage change to the output current change when the input voltage remains unchanged. Current adjustment rate: the time when the output current changes from the maximum value to the maximum value. The resulting relative change in output voltage. Both output resistance and current regulation indicate the impact of changes in load current on the output voltage, so only one of them needs to be tested.

>Types of DC power supplies There are many different types of DC power supplies, the nature of the non-electrostatic force, and the different energy conversion processes. Also different. In chemical batteries (such as dry batteries, storage batteries, etc.), non-electrostatic force is a chemical action associated with the dissolution and deposition process of ions. When a chemical battery discharges, chemical energy is converted into electrical energy and Joule heat in a temperature difference power source (such as a metal thermocouple, semiconductor The non-electrostatic force in the thermocouple is the diffusion effect associated with the temperature difference and the concentration difference of electrons. When the thermoelectric power supply provides power to the external circuit, the thermal energy is partially converted into electrical energy. The non-electrostatic force in the DC generator is the action of electromagnetic induction. When the DC generator supplies power, mechanical energy is converted into electrical energy and Joule heat. The non-electrostatic force in the photovoltaic cell is the function of the photovoltaic effect. The photovoltaic cell supplies power and converts light energy into electrical energy and Joule heat.

>●Simple design. Only a power module with a few discrete components is needed to obtain power.
>
>●Shorten the development cycle. Module power supplies generally have a variety of input and output options. Users can also repeatedly superpose or cross-superpose to form a building-block combination power supply to achieve multiple inputs and outputs, which greatly reduces prototype development time.
>
>●Flexible changes. If the product design needs to be changed, just convert or connect another suitable power module in parallel.
>
>●Low technical requirements. Modular power supplies are generally equipped with standardized front-ends, highly integrated power modules and other components, thus making power supply design simpler.
>
>●The module power supply casing has a three-in-one structure that integrates a heat sink, a radiator and a shell, which realizes the conduction cooling method of the module power supply and makes the temperature value of the power supply approach the minimum value. At the same time, the module power supply is given standardized packaging.
>
>●High quality and reliable. Module power supplies generally adopt fully automated production and are equipped with high-tech production technology, so the quality is stable and reliable.
>
>●Wide range of uses: Modular power supplies can be widely used in locomotives and ships, military weapons, power generation and distribution, postal and telecommunications, metallurgical mining, automatic control, household appliances, instrumentation and scientific research experiments, etc. All areas of social production and life, especially in high-reliability and high-tech fields, play an important and irreplaceable role.
