Delixi uses three-phase regulators need precautions

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 ...

In the process of practical speed regulation, an ordinary frequency-adjustable communication power supply can not meet the requirements of speed regulation and control of asynchronous motors, and must also take into account the effective use of the motor magnetic field, the suppression of the starting current and the acquisition of the desired torque characteristics, such as low-frequency torque characteristics.

Delixi voltage regulator will have a stable preset amplitude of a fixed output voltage, regardless of its input voltage or load conditions change. There are two types of voltage regulators: linear and switched The linear regulator is an active (BJT or MOSFET) operated by a high-gain differential amplifier ...

The circuit breaker insulation incident can be divided into the internal insulation terminal and the external insulation incident. The hazards caused by internal insulation incidents are generally greater than those of external insulation. (1) Internal insulation incidents The internal insulation end is mainly a bushing and a current transformer ...

In the use of soft starters, some users often have some faulty concepts such as: 1. It is thought that whether the motor can start successfully is related to the function of the soft starter, and a good brand or even a foreign brand should be selected under heavy load. 2. When the motor is not ...

The circuit breaker has arc extinguishing equipment, so the circuit breaker can be operated with load, not only the load current, but also the fault (short circuit) current; The circuit breaker has a good package form, so simply observing the circuit breaker cannot intuitively determine whether it is in the closed or disconnected position. Isolate ...

Delixi inverter parameter check setting steps Using the keyboard to set the frequency, we can use the keyboard number direct setting and the keyboard potentiometer setting two methods, and the control method can be selected by modifying the parameter P0.01. ...

The traditional textile printing and dyeing industry is a labor-intensive industry, and the degree of automation is not high. Most of the transmissions used are not speed regulation, and most of the occasions that need speed regulation are DC motors, such as warping machines, sizing machines and many printing and dyeing equipment.

1. Superior performance The new vector control algorithm is adopted, and the starting cabinet is large, the torque response is fast, and the control accuracy is high, which further improves the operation efficiency of the motor. 2. Powerful function and low cost of use Built-in large number of ...

1. Although the air switch is a type of circuit breaker, it is a switch that will automatically disconnect as long as the current in the circuit exceeds the rated current. However, air switches are used in low-voltage distribution networks and electric traction systems, mostly on the low-voltage side. Widely used in the home, such as general household switches ...

1. Classified according to the operating voltage level Low-voltage electrical appliances: electrical appliances used to communicate circuits below 1200V and DC 1500V to play the role of on/off, protection, control or regulation. High-voltage electrical appliances: communication 1200V or more, DC 1500V or more. ...

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 ...

An inverter is usually a device that replaces a constant voltage and frequency with a constant voltage or frequency for a variable voltage. However, in the application, the inverter will inevitably present shortcomings, and when analyzing the shortcomings of the problem, in order to deal with the shortcomings well and quickly, ...

First: Initialize the parameters Before wiring, initialize the parameters. On the control card: select the control method; Reset the PID parameter to zero; When the control card is powered on, the enabling signal is turned off by default; Save this status to ensure that this is the condition when the control card is powered on again. The servo motor ...

1. Extra limit short-circuit breaking can be used for Icu There are two types of breaking capacity targets for circuit breakers: additional limit short-circuit breaking capacity of 4U and additional operating short-circuit breaking capacity Ics. As a characteristic parameter, ICS is not only a brief consideration of the breaking ability of the circuit breaker, but also a breaking purpose.

Delixi leakage maintainer, as a common anti-shock equipment, can quickly disconnect the circuit in the face of leakage, overload, short circuit and other problems in the electrical circuit, useful maintenance personnel safety, to prevent damage to electrical equipment. Volume...

Delixi inverter has launched CDI9000 series inverter, CDI9100 series inverter, CDI9100-S series inverter, CDI9200-G series general-purpose inverter, CDI9200-P series fan pump inverter, CDI9200-ZS series injection molding machine special inverter, CDI9200-GS series ...

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. If strong electricity and weak electricity are to be separated by a long distance from the horizon walking line, the interval should generally exceed 30 cm to prevent disturbance and be interspersed with each other. 2. In order to facilitate the future line change, the PVC pipe must be cut down and straightened as much as possible.

Electrical safety is not a trivial matter in modern society. Delixi communication contactors are used in homes, public places or commercial buildings. As a power device, its importance is self-evident. If you buy an unsuitable communication contactor, it will appear briefly in the future application process ...
