Delixi voltage regulator boot voltmeter does not indicate fault analysis and solutions

Voltage vf and v difference: The two have different meanings, vf on the battery represents the feedback voltage, while v represents the capacity of the battery, which is the unit of measurement of voltage. Lithium battery is a kind of battery with lithium metal or lithium alloy as the positive/negative electrode data and the use of non-aqueous electrolyte solution. ...

1. The output voltmeter is constantly swinging back and forth, and sparks are generated at the carbon brush 1. The contact pressure between the carbon brush and the coil plane is too small 2. The carbon brush is severely worn 1. Clean the coil and carbon brush with a fine file or sandpaper, and then adjust the carbon brush pressure 2. Replace the carbon brushes with new ones ...

1. The safety wire is blown off In a general environment, a blown safety wire indicates that there is a problem with the internal wiring of the power supply. Because the power supply is operated in the shape of high voltage and high current, the fluctuation of the grid voltage and the surge city cause the current in the power supply to increase suddenly and cause the safety wire to be blown off. The focus should be on checking the power ...

1. The use environment of regulated power supply requires good ventilation, no moisture, no corrosive gas, explosive substances, conductive dust Egypt steam, etc., and it is required to be installed in places without intense oscillation. ​ 2. The voltage regulator is used according to the function of the electrical equipment.

With the continuous progress of industrial automation, inverters have also been widely used, energy conservation and environmental protection as the center of China's industrial economic development, in the direction of the sustainable development of China's industry, but also in the effective promotion of the sustainable development of China's inverter profession, so that I ...

1. According to the requirements of the device part and the needs of the maintenance function, reasonably select the motor maintainer model and its various maintenance action parameter settings; 2. According to the requirements of the product operation manual, the correct device should be connected correctly according to the use of each terminal, and the operating power supply should be connected to the control ...

Delixi Electric launched a new "product intelligence" series of products, with outstanding quality and higher cost performance of professional competitiveness, to meet the green consumption demand for low-voltage electrical appliances in the field of construction and real estate, and promote China's low-voltage electrical profession into a new green development era. This "product wisdom" ...

The high-voltage circuit breaker (or high-voltage switch) is the primary power control equipment of the substation, which has arc extinguishing characteristics. When the system is in normal operation, it can intercept and connect the no-load and load currents of lines and various electrical equipment. When there is a problem in the system, it can quickly block the fault with the cooperation of relay maintenance.

In the use of soft starters, some users often have some faulty concepts such as: 1. It is thought that whether the motor can start successfully is related to the function of the soft starter, and a good brand or even a foreign brand should be selected under heavy load. 2. When the motor is not ...

1. There is a problem with an inverter, it cannot operate and the LED shows "UV" (abbreviation of under voltage), which clarifies that the alarm in the book is under voltage of the DC bus. Because the power supply of the control loop of this type of inverter is not taken from the DC bus, but from the AC input through the transformer alone.

Thermal accounting requires information such as power loss, thermal resistance of the package, and ambient temperature. The power loss is calculated in the same way as the efficiency accounting, which is simply the value of the difference between the output input voltage and the input current. The thermal resistance should have a technical standard documented, and if it is not, it is necessary to ask the manufacturer. Basically...

In the process of practical speed regulation, an ordinary frequency-adjustable communication power supply can not meet the requirements of speed regulation and control of asynchronous motors, and must also take into account the effective use of the motor magnetic field, the suppression of the starting current and the acquisition of the desired torque characteristics, such as low-frequency torque characteristics.

1. Failure analysis. 1) Closing fuse, control fuse blowing or poor contact. 2) Poor contact of DC contactor or poor contact of control switch contact and auxiliary contact of circuit breaker. 3) The DC voltage is too low. 4) Closing and locking action. ...

Delixi Group focuses on low-voltage power distribution and industrial automation in the field of comprehensive solutions suppliers, founded in 1984, is a collection of industrial operations, brand operations, capital operations as one of the large enterprise groups, for 18 consecutive years ranked among the top 500 Chinese enterprises. Delixi rangefinder is designed for ...

The spring is a widely used component in the circuit breaker mechanism, and the critical spring has a great impact on the function of the circuit breaker. From the perspective of energy, combined with the installation space of the tension spring, the author uses the existing accounting formula of the tension spring to solve the unknown quantity from the known quantity to obtain the required tension spring parameters.

Delixi control transformer is the most used type is BK, JBK, BKC and other types, these transformers use some precautions as follows! 1. Before purchasing, estimate the total capacity of the electrical appliances used, and choose a transformer with a certain capacity to ensure that it will not burn out when it starts instantaneously.

1. Before the inverter device is in place and debugged, please tighten the components, especially the connecting bolts of the wire part, if not tightened, the connection will be heated and cause fire. 2. The on-site planning of the installation should be reasonable, and the excellent ventilation environment should be maintained. 3. The incoming and outgoing power lines of the inverter are not ...

There are substantial differences between servos and inverters in terms of application intention and function. Which one to choose depends on factors such as operating mode, load conditions, price, etc. Basically, the performance of the servo is superior to that of the inverter. Therefore, when changing from an inverter to a servo, there are generally no operational problems ...

1. Is it possible to put the motor directly into a fixed frequency inverter without using soft start? It is possible at very low frequencies, but if the given frequency is high, the conditions for direct starting of the power supply are similar. A large starting current (6-7 times the rated current) will flow too much, due to ...

1. The pressure of Delixi inverter system is unstable and easy to vibrate? Answer: The pressure of the system is unstable, which may be due to the following reasons: A. There is a problem with the direction of the pressure of the pressure sensor acquisition system, and the pressure collection point is too close to the water outlet of the water pump, and the pressure of the pipeline is affected by the water outlet ...
