Attention to the wiring of the inverter ground wire - Delixi

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.

Variable-frequency drive (VFD) is an electric power control device that uses frequency conversion skills and microelectronics skills to control and communicate motors by changing the frequency of the power supply for motor operation. The inverter is mainly composed of rectifier (communication to DC), filtering, inverter (DC to ditch) ...

01. What is a linear voltage regulator? A linear regulator uses a transistor or FET that operates in its linear region to subtract the excess voltage from the input voltage applied to generate a conditioned output voltage. The so-called voltage drop voltage means that the voltage regulator maintains its output voltage at its ...

First, the principle of energy saving The die-casting machine is a typical periodic variable load equipment, and a complete production cycle includes the stages of mold clamping, injection, cooling, and mold opening and ejection. Usually the power of hydraulic equipment is supplied by a quantitative oil pump, and the motor that drives the oil pump to work has always been rated for its ...

The control of the inverter is nothing more than the fundamental logic of starting, aborting, forward rotation, rotation, and speed regulation, which fundamentally requires that the level condition is effective, rather than the rising edge is effective, so the use of button switches to control the inverter is generally required to use the self-protection of the button...

The low-voltage air circuit breaker is the primary equipment for low-voltage power distribution, and it should be able to operate reliably when the electrical equipment is no-load, load-loaded or short-circuited. Its primary function is to maintain the line and equipment, can turn on, carry and break the current under normal circuit conditions, and can also be used in the specified non-...

Typically, every electrical device or device is designed for a wide range of input voltages. Depending on the sensitivity, the operating scale of the device is constrained to a specific value, for example, some devices can tolerate ±10% of the additional voltage, while others can tolerate ±5% or less. ...

1. It can reduce the impact on the power grid, and there will be no problem of excessive peak-to-valley difference. 2. It can speed up the controllable function, and then speed up the slipping according to the needs of the user; 3. The abort mode of the motor and equipment is controllable, ...

In general, every electrical device or device is designed for a wide range of input voltages. Depending on the sensitivity, the operating scale of the device is limited to a specific value, for example, some devices can tolerate ±10% of the rated voltage, while others can tolerate ±5% or less. ...

1. Conductors 1. Color High-quality copper is called "red copper" or "red copper" – as the name suggests, this copper is reddish, purple, and dark red in color. The worse the copper, the lighter the color and the more yellow it is, which is called "brass". 2. Thickness ...

1. What is a switching regulator? Switching regulator, English (regulatior), some people call it a regulator, a voltage regulator source. To achieve voltage regulation, it is necessary to control the system (negative feedback), from the theory of automatic control, we know that when the voltage rises, it is lowered by negative feedback, ...

1. If the fuse is burned out, please approve the load equipment as soon as possible, make repairs in time, and restore power; 2. If you use a fixed amount of fuse, please use a regular line, and do not match it at will, so as not to cause ...

According to the controlled target and operating parameters such as voltage, current, power, frequency and operating system, the additional parameters of the contactor are determined. 1) The coil voltage of the contactor should generally be lower, so that the insulation requirements of the contactor can be reduced, and it is safer to use. But for the sake of the party ...

Delixi intelligent all-round circuit breaker CDW9 series, should be checked regularly every year, first open and close and long-distance equipment, successively use a variety of additives, test operation program column, control unit test using a small test suite; Every two years or when the control unit repair target reaches 100, it should be ...

On January 27, the "4th China Electrical Appliance Culture Festival and World Electrical Products Expo" was grandly opened in Liushi, Wenzhou, the capital of China's electrical appliances. More than 500 companies from home and abroad showed their faces on more than 1,400 booths. The largest Delixi exhibition hall with a booth area of more than 1,800 square meters ...

　　My name is Inverter, and among the many new energy-saving products, I am known as the "energy-saving forward" for my excellent function. In today's world, extreme disasters occur frequently, with melting glaciers, rising sea levels, persistent droughts, and heavy rainfall.

Variable-frequency Drive (VFD) is an electric power control equipment that uses frequency conversion skills and microelectronics skills to control and communicate motors by changing the frequency of the working power supply of the motor. The inverter is mainly composed of rectifier (communication to DC), filtering, inverter (DC to ditch) ...

A four-quadrant power supply is a power supply capable of absorbing and supplying positive and negative currents and voltages. While a simple voltage converter is capable of generating a fixed output voltage from the input voltage, this feature is not sufficient in some applications. An example is the control of voltage nodes connected to capacitors that ...

First, press the "Cancel Recovery Button" 4 times in a row; Then adjust the clock (the factory has been adjusted), if you need to adjust it again, press and hold the "clock key" together, and then press the "school week, time key, school minute key" to adjust the Beijing time. ...

The so-called "left zero and right fire of the circuit breaker" is nothing more than the order of the sockets - when facing the socket, the socket on the left is the neutral line, the socket on the right is the front, and that's it. Delixi socket wiring may not be "left zero right fire". ...
