Delixi inverter uses the keyboard to set the frequency step

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 ...

Product Introduction With optimized open-loop vector control, V/F control, closed-loop vector control, stable function, function optimization, it is a high-function vector inverter, which can be widely used in speed control accuracy, torque echoing speed...

Most modern LDOs and switching regulators operate reliably under no-load conditions, and some older power devices require a minimum load to ensure stability, because one of the electrodes that needs to be compensated is affected by the payload resistance. For example, the LM1117 requires a load current of at least 1.7 mA (most ...

Voltage regulators have become an integral part of many appliances in household, industrial, and commercial systems. Earlier, manually operated or switchable regulators were used to raise or lower the input voltage to supply the output voltage within the desired range. This stabilizer is built with electromechanical relays as switchgear ...

input/output reactor for frequency conversion speed regulation; Because the inverter is often affected by the impact of inrush current and surge voltage in the process of driving the inverter motor operation governor, which will seriously damage the performance and service life of the inverter and the motor, so it is necessary to install a transmission in front of it.

1. Voltage circuit breaker problem The contact is overheated, you can smell the power distribution control cabinet, by checking that the moving contact is not completely inserted into the static contact, and the contact pressure is not enough, resulting in a decrease in the switching capacity, causing the contact to overheat. At this moment, it is necessary to adjust the operating organization so that the moving contact is completely inserted into the static contact ...

1. Check the time first, if the time of the week, hour and minute is correct, don't care. If it's not correct, you need to take care of it yourself. Conditioning is very simple, you just need to press the clock, and then adjust the week by week, the hour of conditioning, and the minutes of conditioning. ...

Application of air switches (circuit breakers). Delixi air switch, also known as circuit breaker. It is a switch that actively closes as soon as the current in the circuit exceeds the additional current. Air switch is a very important electrical appliance in the low-voltage distribution network and electric traction system.

1. Overcurrent (short circuit) Overcurrent problems are the most common in the side of various faults in the inverter. The problem is mostly due to the following problems: first, as long as the speed converter is reported when starting, it is clear that the overcurrent is very serious, and most of them are load short circuits, mechanical parts stuck, inverters...

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-...

Circuit breaker refers to a switchgear that can close, carry and break the current under normal circuit conditions, and can close, carry and break the current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and ...

Delixi's communication contactor is widely used in industrial electrical, contactor as a kind of electromagnetic switch, its interior is mainly composed of the main and auxiliary contacts and electromagnetic coils, static cores and other parts of the control line connection and breaking. ...

1. Trial delivery and commissioning method The first thing to find is the fault of the remaining current action maintainer itself. The detailed operation method is: first block the power supply, and then remove all the zero-sequence transformer load side leads of the remaining current action maintainer (the second and third level remaining current action maintainers will directly remove the outgoing ...

Contrasting method The specific method is to let the problematic meter and the normal meter operate under the same conditions, and then detect the signals at some points and compare the two sets of signals measured, if there are differences, you can conclude that the fault is here. This method requires maintenance personnel to have considerable knowledge and skills.

It shows that the voltage regulator base is not voltage corrected, and the voltage regulator in this situation is like a transformer, the higher the input voltage, the higher the output voltage, the input decreases and the output voltage also decreases. This...

LDO, or low dropout regulator, is a low-dropout linear regulator that uses a transistor or field-effect transistor (FET) operating in its saturation region to subtract the excess voltage from the input voltage used to generate a conditioned output voltage. ...

First of all, Delixi inverter has a very high control accuracy. It uses advanced electronic skills and digital control skills, and can control the speed, torque, and current of the motor with a high degree of control. Together, the controller of Delixi inverter also has a high overload capacity and strong ...

When the VFD is viewed regularly, the power supply should be blocked, the operation of the VFD should be stopped, and the cover of the VFD should be removed. The first thing is to check the places that cannot be seen without downtime, or the places where it is difficult to find problems on a daily basis, as well as the inspection and adjustment of electrical characteristics. After blocking the VFD power supply, the main power ...

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

Problem depiction: Delixi inverter controller data flying, or the data is occasionally incorrect, how to solve? Solution(s): This is the result of severe disturbances to the controller. Frequently...
