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 ...

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. What is a switching regulator? Switching regulator, English (regulatior), some people call it a regulator, a voltage regulator source. Completing voltage stabilization is the demand control system (negative feedback), from the automatic control theory we know that when the voltage rises, it will be lowered through negative feedback, ...

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. ...

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.

When the Delixi voltage regulator is turned on, the voltmeter does not indicate the problem phenomenon and cause analysis 1. The plug is not plugged in firmly, and there is no output voltage 2. The fuse is broken When the Delixi voltage regulator is turned on, the voltmeter does not indicate the problem is solved ...

The general leakage circuit breaker is used to wire the principle of the upper and lower lines, as long as the phase line and the zero line can be distinguished, between, the zero line is marked with N on the right, and the incoming and outgoing lines are the same. Delixi DZ47LE C40 ...

Delixi CDI-EM60 series inverter is a high-performance communication motor drive, suitable for a variety of industrial use. This kind of inverter has a variety of advantages, such as ** rate, low harmonic distortion, low noise, low oscillation, etc. Delixi CDI-EM60 series inverter can be used in a variety of ...

Thermal accounting requires information such as power loss, thermal resistance of the package, and ambient temperature. The power loss is the same as the power accounting, which is purely the value of the output input voltage difference multiplied by 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...

1. Its overall induction skills are the best, its design does not use electronic devices, and the environmental adaptability and stability 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, ...

There are many soft problems in inverters, which are also one of the problems that generally exist in the operation of various types of inverters. So how can we reduce the occurrence of soft problems in inverters? This is a problem that all inverter manufacturers and users are very concerned about. More on that below. ...

The electrical control system is generally called the secondary control loop of electrical equipment, different equipment has different control loops, and the control methods of high-voltage electrical equipment and low-voltage electrical equipment are also different. Specifically, an electrical control system refers to a combination of several electrical components that are used to complete the operation of a certain ...

Delixi general switching power supply can provide stable DC output products, widely used in communications, LED displays, industrial control, radio and television, computer networks, medical equipment, intelligent monitoring and other fields. Delixi universal switching power supply SA, DA, TA, QA Type 85 - 132 / ...

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. Thermal resistance should have a technical standard documented, and if it is not available, it is necessary to consult the manufacturer. Basically...

Delixi regulator output voltmeter keeps swinging back and forth, and sparks occur at the carbon brush, and the problem phenomenon and cause analysis 1. The contact pressure between the carbon brush and the coil plane is too small 2. The carbon brush is severely worn Delixi voltage regulator has ...

CDB1 miniature circuit breaker is a current-limiting high-breaking miniature circuit breaker with overload and short-circuit maintenance, which is suitable for communication 50Hz, additional voltage 400V and below, additional current 63A and below circuits, as line overload and short circuit maintenance, can also be used under normal circumstances.

1. Repair the damage of the inverter rectifier block The damage of the inverter rectifier bridge is also one of the common faults of the inverter, the inverter rectifier block produced in the early stage is mainly diode rectification, and now some rectifier blocks adopt the thyristor rectification method (voltage regulation and frequency modulation inverter). Middle...

(1) Gain Parameter: The share gain of the speed manipulator. If the gain is too large, it may cause speed fluctuations. (2) Integration time parameter: the integration time of the speed manipulator, that is, the change rate of the output signal of the manipulator under the deviation step signal. The shorter the integration moment ...

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. ...
