Selection of Delta power supply

Delta's inverter has made the motor drive system complete two hopes: first, the motor has completed the operation of higher power; The second is to make the motor controllable and prevent the problem of the big cow pulling the trolley. But the problem in front of the engineer is: there are so many types of motor loads, and the frequency converter ...

(1) The harmonic current will directly cause the additional heating of the motor, so that the stator of the motor will exceed the rated temperature rise of the motor itself, so that the rated output capacity of the motor will be greatly reduced. ​ (2) The current wave output of the inverter ...

1. Install AC reactor and DC reactor. When the capacity of the inverter is greater than 500kva in the distribution transformer, and the transformer capacity is more than 10 times the capacity of the inverter, an AC reactor is installed on the input side of the inverter. And when the output voltage of the distribution transformer is unbalanced and uneven in three phases ...

1. Visually inspect the UPS and battery (or other energy storage) equipment for obstacles, and properly cool the surrounding area. 2. Ensure that there is no abnormal operation or positive warning on the UPS panel, such as: overload or overdischarge of the battery close to it. 3. Check if there is battery corrosion or other shortcomings ...

The converter is capable of manual and active switching: 1. The switching between the manual operating system and the DCS operating system is done by the transfer switch SA installed on the field operation tower, which has active, manual and ...

At present, Delta PLC has ES, EX, EH2, PM, SA, SC, SS, SX, SV and other series. Each series of models has its own characteristics to meet different control requirements. The ES series is cost-effective and can be controlled sequentially. EX ...

The role of the "communication input reactor" of the inverter input device is mainly to improve the power factor of the communication power supply on the communication side of the input side; It is useful to eliminate the higher harmonics on the input side to avoid damage to other electrical equipment caused by voltage distortion; Eliminate the three-phase AC power phase ...

In the inverter problem, it is often encountered that the energized panel does not appear. Generally speaking, the problem of the inverter panel not showing up is usually caused by three parts, one is the poor contact of the contactor, the second is the control panel of the inverter, and the third is the damage of the power module that supplies power to the control panel.

In order to ensure the reliability of production, all kinds of production machinery are designed with power drive, and there is a certain surplus when designing and matching power drive. When the motor cannot operate at full load, in addition to reaching the power drive requirements, the residual torque increases ...

Inverter is a high-tech product, mainly composed of power electronic equipment and microelectronic equipment. The three-phase communication grid is connected to the input of the frequency converter. The input end of the inverter is a rectifier circuit, and the output end is a frequency conversion circuit. As a result, the voltages and currents on the input and output sides include abundant ...

There are many setting parameters of the inverter, and each parameter has a certain selection scale, and the inverter can not operate normally due to the improper setting of a single parameter is often encountered in the application, therefore, the relevant parameters must be correctly set. ...

Not long ago, Delta was awarded the "2020 Excellence Award for Optimal Allocation of Human Resources Resources" by the Human Resource Management Service Project Organization "Future", which stood out from more than 5,000 companies. This is also the second time since 2018 that Delta has won this honor. Delta ...

The main problems of the iron core of the small electromagnetic relay are that the armature cannot be sucked after being electrified: This may be due to broken coils, foreign matter between the moving and static cores, and low power supply voltage. It should be patched on a case-by-case basis. When energized, the armature is noisy: This may be because of the ...

The low-voltage fuse cannot be used as an overload maintenance for the motor. It is necessary that the additional voltage of the fuse is greater than or equal to the operating voltage of the distribution line. It is necessary for the additional current of the fuse to be greater than or equal to the additional current of the melt ...

Delta's inverters should be thoroughly inspected for the first time or after long-term installation. The items and methods of inspection are as follows: 1) Check whether the Delta inverter is damaged, whether the metal parts are rusty, and whether there is frost. If there is frost and condensation, it should be dried for 4 hours (60°C) or ...

1. Before the inverter is energized The temperature and humidity of the surrounding environment should be detected first. Too high a temperature will cause the inverter to overheat the alarm. When severe, it will directly lead to damage to the power supply device of the inverter and short circuit of the circuit; Excessive humidity of the air can lead to a direct short circuit inside the inverter. When the inverter is in operation ...

What are the benefits of inverter power correction? Many brands of inverter power boards, driver boards, and motherboards can be universal, as long as the type, volume, and hardware are the same, and the desired power and voltage value can be obtained by correcting the manufacturer's parameters.

Programming equipment: simple programmer, most only accept mnemonic programming, and some can also be programmed graphically (such as Japan's Toshiba EX programmable controller). The cluttered one has a graphical programmer, which can be programmed in the trapezoidal language. Some also have dedicated computers that can be used for other ...

Delta's servo motor system is planned for industrial use, and it is necessary to have a sufficient understanding of the motor standards and operation manuals before operating the motor. For the safety of the operator and equipment, and to ensure that the motor can be used correctly, please read this safety precaution carefully before installing the machine. ...

1. Vibration circuit: the leakage-source and R4 of the main winding N1 and Q1 of the switching transformer are the channels of the power supply operation current; R1 provides the starting current; The self-powered windings N2, D1, and C1 constitute the power supply voltage of the vibrating chip. The normal operation of these three links is the prerequisite for the power supply to vibrate.
