· The main technical indicators of DC power supply

The main technical indicators of DC power supply can be divided into two types: one is 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). 1. Stability coefficient and stability rateStability coefficient refers to the relative change in output voltage caused by the relative change in input voltage while the load current and ambient temperature remain constant. The voltage regulation rate refers to the relative change in output voltage when the relative change in input voltage is ± 10%. The voltage regulation coefficient and voltage regulation rate both indicate the impact of input voltage changes on output voltage, so only one of them needs to be test...

· Definition and advantages of DC power supply

DC power supply is a type of power supply device that provides direct current energy. It converts alternating current into direct current and provides stable power supply for various electronic devices. This article will provide a detailed explanation of the definition of DC power supply, explore its advantages, and explain its applications in various fields. 1. Definition of DC power supplyDC power supply is a power supply device that converts alternating current into direct current. It converts alternating current into stable and continuous direct current by using circuits such as rectifiers, filters, and regulators. The output voltage of a DC power supply can be adjusted as needed and usually has lower ripple and higher stability.2. Advantages of DC power supplyCompared to AC power sources, DC power sources have several significant advantages:2.1 StabilityDC power supply can provide stable voltage output because it undergoes rectification and filtering processing, resulting in m...

· Will data cable affect the charging speed of mobile phone

Question: Will data cable affect the charging speed of mobile phone?Answer: Yes.A small data cable may not be eye-catching, but its quality and specifications can have an impact on the charging speed of the phone.The thickness of the data cable. Usually, the thicker the wires inside a data cable, the more current it can carry and the faster the charging speed.The length of the data cable. In general, for data cables with the same quality and thickness, the shorter the length of the cable, the smaller the power loss, and the faster the charging speed.Adaptability of fast charging protocol. The charging head and data cable must match the fast charging protocol of the phone to achieve fast charging. It is recommended to use the original charger as much as possible when charging.How to protect data cables well?Don't pull the data cableDuring daily use, do not forcefully pull the data cable. When charging, avoid keeping the data cable tight while playing with the phone.Avoid approaching he...

· What is the voltage of a typical onboard charger?

Generally, there are two types of voltage for an On board charger: 12V and 24V, and the output power varies depending on the settings of the On board charger. In most cases, the output power of the USB interface is 5V1A, which is 5W. Nowadays, many On board chargers support fast charging technology, and the output power may vary accordingly, with the common ones being 5V2A and 9V2A.The On board charger is usually powered by the cigarette lighter interface, and when in use, the cigarette lighter needs to be removed and the On board charger inserted into the cigarette lighter interface. Through the USB interface of car charging conversion, you can provide charging or power supply services for mobile phones or other auxiliary electrical devices in the car.It should be noted that the voltage and output power of the On board charger are related to the settings of the car charger, so careful selection is necessary when purchasing. In addition, the use of on board chargers also requires s...

· What should I do if the charger of a new energy vehicle malfunctions?

When your new energy vehicle charger malfunctions, the top priority is to ensure safety and avoid using chargers that may cause further damage. Here are some professional suggestions to help you deal with charger malfunctions:1. Cut off power: Once a charger malfunction is detected, the power should be immediately cut off to ensure a safe operating environment.2. Check the charger: Carefully inspect the charger for obvious damage, such as broken wires or loose plugs. Do not attempt to repair on your own to avoid more serious damage or safety hazards.3. Contact professionals: Timely contact the after-sales service or professional maintenance personnel of new energy vehicles, consult with them and seek help. They will be able to provide you with professional guidance and advice.4. Do not continue to use a damaged charger: To avoid irreversible damage to the car battery, do not use a damaged charger for charging.In addition, understanding the basic structure of new energy vehicles is als...
