Understanding Pure Sine Wave Inverters and Other Inverter Types When shopping for a marine inverter, RV inverters and car inverters it is important to note that there are two basic types of inverters on the market. Understanding the differences and pros and cons of each of these inverters is important in order to make certain you purchase the type of inverter that will best suit your needs. The two basic types of inverters include: Pure sine wave inverters Modified sine wave inverters Pure Sine Power Inverter pure sine wave inverter, which is also referred to as a "true" sine wave, utilizes sine wave in order to provide your appliances with power. A sine wave, which is produced by rotating AC machinery, is the type of wave that is generally provided by the utility company with the help of a generator. The benefits of using a pure sine wave inverter include: All equipment currently on the market is designed for use with sine waves. Some appliances, particularly microwaves and variable speed motors, will not produce full output if they do not use sine wave power. Some appliances, such as light dimmers and bread makers, will not work at all without sine wave power. On the downside, pure sine wave inverters are more expensive than the other two types of inverters. By looking out for discount inverters that are on sale, however, you can keep your costs down. Modified Sine Power Inverter The modified sine inverter is different from a pure sine power inverter because the wave is in more of a step wave and because appliances are not specifically designed to work with this type of inverter. Although many appliances will still work with a modified sine inverter, some may not work as efficiently. As such, it may take more power to run appliances with a modified sine inverter. Using fluorescent lighting can be problematic when using modified sine power inverters. For example, they may not get as bright and some may make buzzing noises when on. Certain appliances with digital clocks or electronic timers may also work improperly with this type of inverter because the waves are rougher and cause extra "noise" to be created in the line. Furthermore, appliances that use electronic temperature controls will not be able to properly control the temperature when using modified sine wave marine inverters, RV inverters or car inverters. Despite the few problems associated with them, most equipment can run just fine with modified sine wave inverters. In addition, since they are less expensive than the pure sine wave inverters, they are the most commonly used inverter. In fact, it can sometimes be difficult to find options other than modified sine wave inverters. Regardless of the type of inverter you use, you will also need to acquire the proper power inverter cables. Your power inverter cables need to be the proper size in order to guarantee damage does not occur. For most people, pure sine wave inverters are the best choice for meeting all of their on-the-road needs.http://www.yiyenele.com/products/proshow-565.html |

Uninterruptible Power Supply Can an uninterruptible power supply (UPS) Help You? An Uninterruptible Power Supply (UPS) only has one mission, to protect the load when the power goes out. Everything else that a great salesman wants to tell you is meaningless. When the competition shows up to the game, everything from MTBF to Efficiency becomes the subject of conversation. The truth is, all UPS manufacturers equipment can get the job done. In the end, it comes down to, who you are more comfortable (no liars allowed) and who has the right people to service you. What is the difference in Power Systems & Controls topology? Our topology needs to be discussed in 2 ways, Rotary Uninterruptible Power Supply and Static Uninterruptible Power Supply. Our Static Uninterruptible Power Supply (UPS) is the latest in IGBT/IGBT topology which has also been adapted by a small number of other UPS manufacturers available today. The Static Uninterruptible Power Supply (Continuum) performs in the mission critical arena very well. Our Rotary Uninterruptible Power Supply (UPS) topology is only available with 2 companies worldwide and whether it is PS&C or not, a Rotary Uninterruptible Power Supply (MC or XC) is nothing less than Bullet Proof.http://www.yiyenele.com/products/proclass_426/ |

Plastic Sheet extruder Plastic Ingenuity’s commitment to quality at all phases of the packaging process was the primary motivating factor in our decision, in 1976, to extrude our own plastic sheet material for use in our packaging products. Plastic Sheet extruder is the first step in the thermoforming process; many companies contract with third party suppliers to buy already extruded materials to use in their manufacturing operations. At Plastic Ingenuity, we perform our own Plastic Sheet extruder for most of our resin types and, as a result, can offer our customers superior traceability throughout the entire design and manufacturing process. Major Advantages Because we do the work in-house, we can exercise more complete control over scheduling and provide improved turnaround times for our customers, allowing them to respond quickly to changes in the marketplace. This also provides significant cost advantages that are typically passed through to our customers. We can extrude plastic in a variety of different base materials and blends. These including the following: PET, utility PET and PET side-by-side; HIPS, utility HIPS, HIPS side-by-side, HIPS clear blends crystal and Finaprene rubber blend and HIPS high-gloss co-ex; PETG; HDPE; ABS; Barrier laminates; and Homo-polymer and co-polymer polypropylene. Plastic Ingenuity uses ten state-of-the-art extruders and monitors all sheets produced with atomic gauge scanners; we can produce consistent gauges ranging from .010” to .080” and sheets up to 55 inches in width. This level of control over every part of the process allows PI to provide faster and more cost-effective services for our customers.http://www.plasticcupmachine.com/products-2.html |

vacuum thermoforming machine vacuum thermoforming machine In addition to their use for interior items, plastics are increasingly being used on the exterior of vehicles. Colour-coated foil materials can be used to substitute complex coating processes. The goal is to create a top-class surface finish. This is done by using a positive highly-polished vacuum-capable thermoforming tool to form the components in clean-room conditions. The subsequent back-injection or back-pressing process provides the required dimensional stability. Use the Essix? vacuum thermoforming machine with Essix? Brand Plastics to fabricate removable dental appliances like retainers and whitening trays right in your office. BC-700/1200A-1 Full vacuum thermoforming machine is designed by the principle of mechanical-electrical-pneumatic integration. It adopts PLC control system, panel and digital power control.

City Weekend Review City Weekend Review On a rainy week day night, we walked into Green Massage’s Xujiahui location with aching tension in our backs from hours of sitting in front of the computer screen. Since Green Massage specializes in Asian pressure point massage, we knew we’d be in for a good experience with its 70-minute traditional Chinese massage. After we changed into our satiny, lavender pajama sets, massage shanghai, Vivian, greeted us with a cup of fragrant flower tea. The massage began at the back of our necks, as her fingers applied medium, but insistent pressure on points in the soft area below the base of the skull. She alternated to a lighter motion, gently kneading our necks to further reduce the tension. Using this technique, she massaged outwards to our limbs and down to the base of our spines. Grabbing our arms and then legs, she gently twisted them to stretch out the muscles. With each area, she had the impressive ability to press the right points between the bone and muscle, squeezing the muscle tension out like some sort of liquid. Her attentions were surprisingly gentle though so efficient. That delicate but focused approach makes all the difference. Too many times we’ve paid for a traditional Chinese massage, the cheapest massage shanghai option in most salons, only to have our prone bodies pounded by an indiscriminate flurry of arms. Green Massage raises the bar with a treatment that focuses on applying light, directed pressure to specific points on the neck, back and waist to relieve soreness. We walked out completely satisfied and much less sore than before. http://www.shkeji163.com/ |
