Light-emitting diodes (LEDs) and sensors are directly woven into textile fibers for health monitoring, new nano-sensors have spawned wearable smart textiles, silk fibers imitating comet moths have been made into super-porous multi-functional fibers, etc... Textile black technology has emerged in recent years. They emerge in endlessly, bringing more convenience to our lives.

Intelligent textiles integrate textile, electronics, medicine, computer, physics, chemistry and other technologies. They can sense environmental changes and respond accordingly. They play an important role in improving the quality of life and meeting the needs of special industries. They are the future development of the industry. The main direction, but the operating environment of textile machinery is harsh. To achieve large-scale mass production, production equipment must be efficient and reliable to match the development needs of the industry.

1. Dust-proof, moisture-proof and vibration-resistant

Starting from the application environment, textile production equipment has special application conditions and certain risk factors:

1) Fan: During the operation of the equipment, a lot of lint and dust from textiles will inevitably be produced. The fan will blow these objects into the power supply, causing a potential short circuit. Moreover, lint and dust can easily block the fan, causing the power supply to fail. get dissipated and thermally damaged.

2) No protection: If textile lint and dust fall into the power supply, without protective measures, it will easily cause an internal short circuit in the power supply, causing damage. In severe cases, the internal cotton may catch fire and cause a fire.

3) The product is damp: The shell has holes and the hollow structure inside the shell cannot block water vapor. At the same time, the air inlet of the fan becomes a passage for moist water vapor. When the internal environment of the power supply is not closed enough to block water vapor, harsh indoor and outdoor environments, outdoor environments, etc. will directly affect the life of the power supply and equipment.

4) Strong vibration environment: Textile equipment usually uses processes such as vibration, pulling, and impact to separate fibers and remove impurities. Therefore, there are high requirements for the anti-vibration ability of the power supply.

2. Strong environmental adaptability

The conventional input voltage range is 85-264VAC, which cannot cope with all situations. For example, when the equipment is started and shut down, the input voltage exceeds 264VAC instantaneously, and conventional products are at risk of damage; for example, during high and low peak power consumption periods, large voltage fluctuations can exceed 264VAC; for example, equipment There is demand for exporting overseas, and it cannot meet overseas electricity standards.

weho's fanless semi-filled power supply LMF-UH series products have a wide input voltage range of 85-305VAC, which is not afraid of power grid fluctuations; in addition, the product's operating temperature range is: -40 to +85℃, lower operating temperature, broadening the application area. Suitable for lower environment applications, fast startup is not limited, specially designed for conductive heat dissipation scenarios, no derating in 55℃ windless environment.

At the same time, the LMF-UH series can also maintain 1.5 times the peak power output for 1 second, meeting the transient high current demand of the motor when starting up. It is widely used in strong vibration environments of knitting machinery, spinning machinery and other equipment, providing customers with Come to a better choice.

2. Typical application solutions in the textile industry

In the textile equipment system, after the front-end power supply LMF350-23B24UH is connected to the mains input, it outputs 24V to power the back-end PLC, stepper motor and other components. The product can achieve 1.5 times the peak power output for 1 second to meet the back-end motor start-up generation. The transient large current; the back end is connected to URB2405YMD-6WR3 to step down to 5V to power the LCD touch screen.

The power supply of textile machinery needs three-proof protection and meets certain vibration level requirements; lint is easy to accumulate inside the equipment, causing power failure. Weho LMF-UH series not only meets the above needs and ensures high reliability, but also takes into account the advantages of domestic brand, complete protection functions, fast delivery, and localized fast service, bringing customers a better choice
