The difference between Delixi air switch and leakage protection switch

The so-called DC-DC is actually DC to DC voltage, of course, LDO is also a kind of DC-DC, and only LDO can only achieve step-down. The general DC-DC is mainly converted from DC to AC communication through the self-excited vibration circuit inside, so the external inductance and capacitor are required to achieve LC vibration (and LDO is only ...

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. ...

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". ...

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...

All large AC power blocks are connected by a three-phase transformer for transmission and distribution at high voltage levels. Single-phase transformers can be electrically connected to form a three-phase transformer bank in a distribution system. But the standard is to combine a single phase coil into a three-phase transformer unit on a common core ...

The inverter is a device that can control the speed of the motor, and it completes the speed regulation by adjusting the voltage and frequency of the motor. When selecting an inverter, there are several factors to consider, including the power of the motor, the type of load, the operating environment, etc. This article will specifically introduce the selection of frequency converters ...

Delixi high-precision fully active AC voltage regulator uses linear integrated circuits to form a control system, controls the servo motor, drives the contact voltage regulator to actively regulate the voltage, and is equipped with delay, overvoltage, undervoltage and overcurrent maintenance functions. The product has high efficiency, the same input and output voltage waveforms, and the output ...

Three-phase communication servo motors are widely used, but after long-term operation, various problems will occur. Timely identification of the cause of the fault and corresponding treatment is an important task to prevent the spread of the fault and ensure the normal operation of the equipment. One...

There are many kinds of manufacturers and brands of electrical equipment and sales of electrical equipment on the market, we must choose the authentic brand of Delixi Electric when buying, and we must buy from regular dealers to avoid buying fakes. Everyone calls the electric tiger because electricity will form poles when it is not used properly.

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, ...

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's three-phase circuit breaker is generally divided into three types, namely 3P, 3P+N and 4P. (1) Differences: 3P: Pure three-phase electrical equipment only uses three wirings, and in the case of no single-phase load, it trips when it is short circuited to ground or phase; Otherwise, when a one-phase N-line load is generated, the N-line is disconnected ...

Whether it is a linear regulator or a switching regulator, their daily protection must start from the following aspects: 1. Always observe whether the cooling fan and transmission organization of the voltage regulator are operating normally, check whether the input voltage and load exceed the rated scale, and deal with the abnormalities in time.

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

Delixi 3P air switch, rated current 630A, rated voltage 380V. The Icu=Ics=70kA of this circuit breaker. When the short-circuit current reaches 70kA, can the circuit breaker still be used? If it works, the ICU is already at its limit, which is a contradiction. If it can't be used, ICS is 70KA, which means ...

When buying wires, the first thing to look at is two aspects: conductors and insulation. 1. Conductors 1. Color High-quality copper is called "red copper" or "red copper" - the color of this copper is red, purple, and purple-red. The worse the copper ...

Inverter selection is a skill, if the selection is not appropriate, it may damage the inverter explosion, and seriously affect the normal production of the factory, so it is very important to select the inverter scientifically and reasonably. The following are the principles of inverter selection: ...

The fuses should be installed on the lines of each phase. It is strictly forbidden to install fuses on the neutral line of the two-phase three-wire or three-phase four-wire circuit. Fuses are mainly used for short-circuit maintenance. When the fuse is used for blocking purposes, the fuse must be installed.

We are able to compare the values of resistance and hose diameter (conductance vs. practical diameter). Regarding metal wires, this analogy works well. Small-diameter wires have a higher resistance than large-diameter wires made of the same metal. ...

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...
