Ethernet Switching - What You Should Know

  Local Area Networks (LANs) were once accustomed to the use of connectors like repeaters and hubs until Ethernet Switches came to be in the 90s. Connectors, as their title implies, are those additional pieces that make computers possible to connect . But the specific Ethernet Switches function at the OSI model's data link layer 2. Categorized under "network bridges" , these switches are unlike the also known router . With Ethernet switching, information transfer happens to all connected network devices regardless of which is which. With routers, on the other hand, the relay of data is restricted to a specific device in the network. In Ethernet networking technology , the term Bridges could take the place of Switches and the same applies the other way around. Although, a connector must be completely tested and proven to comply with the Ethernet 802.3 networking standard for it to deserve the title of being an Ethernet Switch . Ethernet Switching, although highly simi...

How Do Solid State Relays Work?

  Solid state relays are one of many relays. A relay is a switch operated by electricity . Very often, a relay uses an electromagnet to mechanically run a switching mechanism . They are most often used when it is necessary to control a signal that has a low power signal, or where different circuits work with a single signal. Historically speaking, telegraph signals were the first to use relays. They then moved on to telephone exchanges and also the earliest computers. There are many different types available, including those that can deal with higher powers or electric motors . Solid-state relays work in circuits that do not have any moving parts. They use a semiconductor to make a switch. The different types can also protect from faults or overloads , which is why they are also often described as being protective . There are two main types of solid-state relays. The first is the regular relay, which uses an electronic part. This gives the same type of function as an electromechan...

Eaton PW9130 Review

  Storing and accessing sensitive data is very important. Similarly , someone who has to work on servers or maintain a server cannot afford to switch it off or lose power as it would lead to disaster for the critical jobs they handle. A strong power backup is the most essential important in these cases. Nothing does the job better than Eaton pw9130 . It is a powerful UPS that can provide the required backup for a long time. It can handle both the 50Hz and 60Hz voltage and provide uninterrupted power backup till the main power is restored. Equipped with ABM battery charging technology the UPS can provide non-stop power backup in cases of power failure. The minor voltage fluctuations and any power spike can be handled well by the product. In normal times it runs on normal power during normal time but in case of a power outage, the power is drawn from the battery. It is also fitted with the latest updates and power management software that helps the battery handle the power source...

Why Choose to Update Your Heating Controls

  You can keep your heating system up to date and modernized by considering installing or updating heating controls . Heating controls can be vital in keeping your heating costs down with thermostats and timers providing automatic on and off options, allowing you to control when your central heating systems switches on and also allowing you to control the actual room temperature . You can achieve full control over your heating system by installing heating controls, allowing you the flexibility to precisely manage your central heating, the time zones, and the temperature levels. With clocks and timers, you can oversee the amount of time your system will switch on at whatever time of day. You can even set it up so it switches on at a certain time of day and off again when you so wish. Some homeowners also install heating valves and stats to control the flow within the system. You can find all these heating products and supplies at reputable suppliers . They will stock plumbing and he...

Poorly Designed & Installed VFDs Can Do Serious Damage

Image
  Recently there’s been a number of articles with regards to VFDs and motors controlled by them being burned out. Much of this comes from the problem of a VFD using a pulse width modulation that at peak voltages becomes strong enough to burn through the insulation protection in an equipment’s motor and fry the related windings. The other problem that contributes to this situation is matching a VFD to a motor that is not designed to be controlled or powered by a VFD, a common mistake matching older equipment to newer VFD controls. The other issue that can occur are shaft currents. A VFD connected to a motor and pulsing through a motor shaft can prematurely burn out motor bearings. This problem occurs due to arcing. The VFD sends electrical charges through the shaft which ultimately transfer through the bearing balls, causing pitting. That in turn causes deterioration of the bearing and ultimately failure of its rotational capability . Bad Design and Poor Application Add to Regr...
