The basic component of the inverter is LS power generation

1. It is used for switching control The ability of PLC to manipulate switching quantities is very strong. The number of points in and out of the control, less than a dozen points, dozens of points, more can be hundreds, thousands, or even tens of thousands of points, because it can be networked, the number of points is almost unlimited, no matter how many points can be controlled, the control ...

The inverter is composed of many electronic parts, such as semiconductor components, etc., in the operation and maintenance involves the replacement of a related component, because of the composition or physical characteristics of the inverter, it will deteriorate in a certain period of time, so it will reduce the characteristics of the inverter, and even ...

1. When the power supply is now powered or the inverter is in operation, do not open the shell of the inverter. Otherwise, an electric shock may occur. 2. When the front cover of the inverter is opened, do not run the inverter. Otherwise, you may be subjected to ...

Now enterprises need to use a lot of ventilator inverters, the larger the scale of the enterprise, the more production workshops, the more ventilator inverters will be used. However, no matter how large the enterprise, there is a primary ventilator inverter, the selection of this kind of inverter is very important, because if there is no ...

How LS Contactor Works: Generally, after the contactor coil is energized, the entire coil current will generate a magnetic field, which will make the core inside have electromagnetic attraction to attract the core, and let their communication contactor point action normally closed contact disconnect, or close, which ...

1. Problem phenomenon: servo error OL, servo motor can not start, and there is abnormal sound problem analysis and possible causes: (1) Bearing damage, foreign objects falling and stuck, stator magnet bursting and falling or moving tissue jamming caused by the motor itself. (2) ...

Solid state relays consist of three parts: the input circuit, the barrier (coupling), and the output circuit. Input Circuit: According to the different categories of input voltage, the input circuit can be divided into DC input circuit, communication input circuit and AC-DC ...

Frequency conversion motor refers to the motor that runs continuously with 100% rated load in the range of 10%-100% rated speed under standardized environmental conditions, and the temperature rise will not exceed the allowable value of motor calibration. Communication contactors are not necessary for frequency converters and are built in, ...

LS touchers are divided into AC touchers (voltage AC) and DC touchers (voltage DC), which are used in electricity, power distribution and consumption. Toucher broadly refers to the electrical appliances that use the current flowing through the coil to generate a magnetic field in industrial electricity, so that the contacts are closed, so as to control the load. ...

1. The load is too heavy, the load carried by the motor is too heavy, or in other words, the resistance torque of the production machinery exceeds the additional torque of the motor. 2. Use improper overload, for example, increase the operating frequency of the inverter to the extra frequency of the motor, and the motor is in the extra frequency.

The basic method of switching the power supply of the device requires us to carry out the corresponding installation and debugging according to the specific model and the device environment. And in the process of installation, we need to pay more attention to safety and stability to ensure the normal operation of the switching power supply. ...

A transistor is a solid-state semiconductor device with a variety of functions such as detection, rectification, amplification, switching, voltage regulation, and signal modulation. A transistor is a variable current switch that can manipulate the output current based on the input voltage. Unlike general mechanical switches (e.g. Relay, swit...)

Features of SUSOL series circuit breakers: It can be used as the main switch of electrical equipment, and the limit breaking ability is high, Icu=Ics Modular construction of circuit breakers: Tripper replacement (TS series) can be combined in a variety of combinations, such as ...

The Viet Nam Professional Football League, sponsored by LS Group, began operations in June and is hosted by Viet Nam Professional Football Joint Stock Company. With the comeback of football events such as the Korea K League and the Bundesliga, more and more football events are also brewing to restart. ...

1. Improper device: The motor is not concentrious with the equipment being dragged, resulting in excessive radial load on the motor, which eventually leads to metal exhaustion. When the radial load on the extension end of the motor shaft is too large, it will cause the motor shaft to have zigzag deformation in the radial direction. When the motor rotates, the shaft's ...

An important difference between servo and frequency conversion is that frequency conversion can be without encoder, while servo must have an encoder for electronic commutation. 1. What the two have in common: The skill of communication servo itself is the learning and application of ...

　　The main functions and functions of PLC: 1. For sequential control: sequential control is based on the current and pre-historical situation of the input switch, and produces the required switching output, so that the system can operate in a certain order. ...

Motion control has a significant period characteristic, it is a combination of a variety of high-tech to push industrial automation, office automation and home automation to a higher stage. At present, the motion control is mainly composed of three parts: inverter, motor and controller. ...

(1) When the inverter is connected to the power grid of large-capacity power transformer (more than 500kVA), perhaps the same power transformer is connected with a thyristor converter without using a commutation reactor, or when there is a switching capacitor bank for power improvement in the same power grid, an AC reactor or DC reactor should be equipped.

1. Wiring of fire emergency lighting Generally, the flame retardant wire is used to wear the metal pipe and the thickness of the protective layer is ≥ 30mm.
