Delixi rangefinder analysis

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 ...

Delixi's three-phase circuit breaker is generally divided into three types, namely 3P, 3P+N and 4P. (1) Differences: 3P: Only three wirings are used for pure three-phase electrical equipment, which trips when there is no single-phase load to the ground or when there is a short circuit between phases; Otherwise, when a one-phase N-line load occurs, the N-line is disconnected ...

Delixi solid state relay and Delixi communication touch device are more used products, so what are the advantages of solid state relay compared to communication touch device, how should we choose when we can choose? 1. First of all, solid...

1. Pay attention to the maximum value of output current: this is a very critical parameter, the current used exceeds the maximum output current of LDO, then the voltage is unstable, and the system will fail. LDO limit parameters: The output current is considered according to the 2/3 criterion. The cost of the whole system ...

(1) Ferromagnetic resonant communication regulator: a communication regulator composed of a full choke and a corresponding capacitor, with constant voltage voltammetry characteristics. The full type is a typical structure in the early stage of this type of regulator. It has simple structure, convenient production, wide allowable scale of input voltage, reliable operation, and overload energy.

The correct choice of Delixi inverter is very critical to the normal operation of the control system. When selecting a frequency converter, it is necessary to fully understand the load characteristics driven by the frequency converter. In practice, people often divide production machinery into three types: constant torque load, constant power load and fan, water pump ...

1.AC/DC the use of power supply Schematic diagram of the use of low-dropout linear regulators in AC/DC power supplies. In this circuit, the alternating current is stepped-down by the power transformer to obtain the AC low voltage, and then through the rectifier filter circuit to obtain the unstable DC voltage, and then through the low dropout linear voltage regulation.

1. Motor encoder alarm 1. The cause of the failure (1) Wrong wiring; (2) electromagnetic disturbance; (3) Encoder hardware damage caused by mechanical vibration; (4) Pollution caused by the on-site environment. 2 ...

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. ...

Varieties of circuit breaker accessories It is divided into two categories: in-flight accessories and out-of-flight accessories. The accessories in the machine are the subordinate equipment of the equipment inside the circuit breaker, including four types: shunt tripper, undervoltage tripper, auxiliary switch and alarm switch. Normally the in-flight accessories have to be uncovered with the device, but now ...

The type of inverter is selected according to the type of production machinery, speed regulation range, static speed accuracy, and starting torque requirements, and it is most appropriate to decide which inverter is the most suitable to use. The so-called suitability is not only easy to use, but also economical, to meet the basic conditions and requirements of technology and production. ...

1. Ability to adapt to the environment When the motor on the bus starts in a group, when the bus is the largest motor unit starts, the impact on the operation of the inverter, which is related to the input voltage fluctuation scale parameters promised by the inverter, for thermal power units should ensure that the bus voltage drops by 30% when the frequency conversion ...

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. ...

Delixi Electric launched a new "product intelligence" series of products, with outstanding quality and higher cost performance of professional competitiveness, to meet the green consumption demand for low-voltage electrical appliances in the field of construction and real estate, and promote China's low-voltage electrical profession into a new green development era. This "product wisdom" ...

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.

In Delixi voltage regulator, the voltage correction from and under voltage conditions is performed through two basic operations, namely Oersted and step-down operation. These operations can be switched on and off manually or automatically by electronic circuits. Under voltage conditions, the voltage of the boost operation is increased to the rated voltage.

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 ...

In the design of Delixi power distribution system, the selective cooperation between the upper and lower levels of the circuit breaker must have "selectivity, rapidity and sensitivity". Selectivity is related to the cooperation of the upper and lower circuit breakers, and the speed and sensitivity are related to the maintenance of the characteristics of the appliance itself and the way the line operates ...

1. The device of the inverter 1.1 The device environment requirements of the inverter Ambient temperature - 10 °C - 40 °C; Ambient humidity: The relative humidity does not exceed 90% (no condensation); Other occasions requiring no direct sunlight, no corrosive gas and flammable gas, less dust, ...

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