Delta's inverter failure analysis

There are many models of Delta's power supplies, and the currents and functions supported are also different, so how to choose? 　　VX Series Power Supplies. VX270: Active PFC270w, but 12v is still small and can only be used at low power. Active PFC and 12v output up to 276w at 300...

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.

1. The problem of the inverter and the motor itself If the motor has been used for a long time, it is not good to clean the insulation function, or the bearing may be stuck, and it may show a large current and heat. The coupling between the motor and the load may also be worn, or the motor is unbalanced, the fixtures of the motor are loose, etc.

Delixi Electric's newly launched CDQ1F series PC-level excitation active transfer switch, with more complete specifications and stronger functions, the power-off time can be shortened to less than 0.1s, escorting the continuous use of electricity in important places! CDQ1F Active ...

Intelligent machining solution plan Intelligent machinery is an important step towards intelligent manufacturing, in order to help manufacturers improve productivity or complete a few diverse forms of production, Delta will exhibit the intelligent processing solution plan at TIMTOS x TMTS 2022, which will be used to communicate with industrial-grade managed Ethernet networking.

All electronic equipment (including frequency converters) will generate some high-frequency or low-frequency noise during normal operation, and disturb the peripheral equipment through conduction or radiation. If the right EMC filter can be configured and the correct device method can be used, the disturbance can be reduced to a minimum. ...

The preparation of the braking resistor of the inverter is mainly to consume part of the energy on the DC bus capacitor through the braking resistor to prevent the capacitor voltage from being too high. Theoretically, if the capacitor stores a large amount of energy, it can be used to release it to drive the motor and prevent energy waste. However, the capacitance of the capacitor is ...

1. Harmonic problems The equipment that plays the role of switching in the main circuit of the inverter must generate harmonics in the process of turning on and off the circuit. The lower harmonics generally have a greater impact on the motor load and cause torque ripple; The higher harmonics increase the leakage current of the inverter's output cable, making ...

Delta's A2 series servo system is one of the more common and used servers on the market today, and the following describes the fault details of the azimuth controller in the repair of Delta's A2 servo drive and the corresponding repair methods Delta ...

What is the effect of speed regulation of fan inverter? According to the query materials, in industrial production, the throttling loss of the damper, baffle and other related equipment of the fan, as well as the protection and maintenance costs account for 7%-25% of the production cost.

1. The touch screen is controlled by PLC inverter 1. Now the general control of the inverter needs to use PLC to communicate with the inverter, read the information of the inverter, and then the touch screen communicates with the PLC in order to complete the control of the inverter to start, stop, and monitor the operation of the inverter.

Recently, Delta Group has made a big hit in the field of building automation with the launch of the DVPSCM52-SL, a slave communication module that supports BACnet MS/TP (Building Automation Control Network Communication Protocol). Building automation system is an indispensable part of intelligent building.

There are many types of Delta contact screens, of course, the parameters of different types are different, and the most important product is DOP-B03S201. This product is a 4.3-inch screen, its aspect ratio is 16:9, the screen is made of TFT raw materials, and its resolution can reach 480X ...

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 ...

Most inverter brand products can rely on the heat of internal electrical components to remove moisture during normal use. If you don't use it for a long time, it's easy to get wet. The chip pins, penetrating resistors, capacitors, and inductor pins of the DIP package will be severely rusted or desoldered, resulting in on-resistance ...

1. The inverter must be selected correctly. 2. Read the product manual carefully, and wiring, device and application in accordance with the requirements of the manual. 3. The inverter device should be firmly grounded to suppress radio frequency disturbance and avoid electric shock caused by leakage of the inverter. 4、 ...

Delta's Ultron HPH series UPS has an AC-AC efficiency of up to 96%, and can reach 99% in ECO mode, with significant energy savings. The flexible airframe provides a compact footprint (40kW / 0.15 m2) and reduces space waste. With an interface-friendly 5-inch colorful touch screen, ...

Problem Description: What is stall avoidance? Solution(s): If the given acceleration and deceleration time is too short, the output frequency of the inverter changes faster than the motor speed, and the inverter will stop working due to overcurrent, which is called stalling. In order to make the motor ...

The box structure of the inverter should be adapted to the environmental conditions, that is, the temperature, humidity, dust, pH, corrosive gas and other elements must be considered. There are several common types of structures that users can choose from: 1) Open IPOO ...
