The difference between Delixi LDO and DC-DC

After long-term use or too frequent movements, or improper daily maintenance, problems may occur during operation and affect the normal operation. Frequently asked questions are as follows: 1. Coil problem The first problem with the coil is because of the ...

In the project, because of the 630 A circuit breaker wiring bar in the 500 kVA box-type transformer, see the second circuit breaker and circuit breaker on the left in the figure. The temperature of this corresponding region is significantly higher than that of the other two corresponding regions, and the other two phases are also hot, and the copper bars of this phase have turned white. There is no induction Deli ...

On March 12, Delixi Electric partner Qingdao Hengtong Ruide received an order, continued to deploy a batch of components to be shipped to Laixi cabin hospital, Delixi Electric strategic cooperation plant Qingdao Fengtai Electric overnight deployment, 24 hours smoothly completed handover, escort for Qingdao war epidemic. ...

Delixi's three-phase circuit breaker is generally divided into three types, namely 3P, 3P+N and 4P. (1) Differences: 3P: Only three wirings are used for pure three-phase electrical equipment, which trips when there is no single-phase load to the ground or when there is a short circuit between phases; Otherwise, when a one-phase N-line load occurs, the N-line is disconnected ...

1. Cooling fan (2-3 years) As long as the inverter is in use, the cooling fan has always been running, so the cooling fan is generally the shortest service life of the accessories, generally after the use of the cooling fan for 2-3 years, the bearings, balls, motors, etc. of the fan are seriously worn, and they need to be replaced.

1. Its overall inductive skills function is the best, its design does not use electronic equipment, and the environmental adaptability and stability and reliability function are the highest. When the capacity of most power grids is sufficient, the voltage is relatively stable, but with the improvement of electrification and informatization, the pollution of some power grids, ...

If the zero line of Delixi's air switch is reversed to the front, there is not much obstacle to the 2P circuit breaker and 2P leakage circuit breaker. The only effect is that it looks irregular, and you need to find the zero line from scratch when repairing, which brings a little inconvenience. ...

The advantages of linear DC regulator are high stability, small ripple, high reliability, and easy to make a multi-output connected adjustable power supply. The disadvantages are large size, bulkiness, and relatively low power. There are many kinds of this kind of regulated power supply, which can be divided into regulated power supply, stabilized current power supply and ...

1. The aesthetic slab adopts frameless large buttons and fluorescent grid planning, giving people a comfortable texture experience. The large-pitch flat panel is simple and useful, and is available in four colours: Funky White, Champagne Gold, Starlight Silver and Midnight Black. 2 ...

Shanghai, September 19, 2018 ---- Today, the 20th China International Industry Fair (hereinafter referred to as the "Industry Fair") officially kicked off in Shanghai. From the perspective of a new breakthrough in the integration of manufacturing and the Internet, this year's industry fair focused on showing the scientific and technological innovation of China's manufacturing profession.

Delixi built-in bypass soft starter CDRA-K3 series is a set of soft start, soft parking and multi-functional protection in one of the motor control equipment. Realize a smooth starter motor without impact during the entire starting process. CDRA-K3 series has built-in bypass contactor and control power supply.

1. The socket quality is low quality First of all, we should check whether the socket is a miscellaneous and inferior product, the copper clamping force in the defective socket is not good, resulting in poor contact between the socket and the plug, and the socket and plug will heat up after a long time of electrical use. So be sure not to buy cheap miscellaneous ...

There are three types of motor inverters ●Ordinary function type. The fundamental V/F frequency conversion speed regulation function, speed regulation accuracy and torque control function requirements are not high for general use can be satisfied. ●High function type. V/F frequency conversion speed regulation with torque control function, hoist constant ...

Delixi switch socket real and false distinction 1. Appearance The shape of genuine Delixi switches is relatively fashionable, looks beautiful, neat appearance, and other impact resistance functions are relatively strong, not easy to crack or turn yellow. Whereas...

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) The additional operating voltage of the circuit breaker ≥ the additional voltage of the line. (2) The additional current of the circuit breaker ≥ the line load current. (3) The additional short-circuit of the circuit breaker can be turned on and off to ≥ the maximum shortness that may be present in the line.

1. The output power of the voltage regulator is the maximum power Basically, most of the nominal power of household appliances refers to active power, and the so-called refrigerators, air conditioners and those water pumps used in the home, etc., most of them are also inductive loads that start instantaneous currents.

1. The capacitance is generally indicated by "C" plus a number in the circuit (e.g., C25 indicates the capacitance numbered 25). A capacitor is an element composed of two metal films that are placed next to each other and separated by an insulating material. The characteristic of the capacitor is first and foremost the communication through the DC block. The size of the capacitance is ...

Since it is used as a low dropout voltage regulator, the first feature is the extremely low input and output voltage difference, and secondly, it also has stable voltage output, low noise, small ripple, small size, and simple peripheral circuits. If an LDO regulator is used when planning the circuit, the general requirement is at least ...

Features of the soft starter: The motor can be soft-started, soft-stopped, and soft-stopped. It can achieve a small impact on the machine-to-power grid. It is much smaller than the Star-Delta starter and the installation is simple. Frequency converters ...
