all-about-relays

In recent news, TE Connectivity, a global manufacturer that specializes in making products for harsh environment, came out with their newest relay product design. This relay is built to their company standards with an outer-covering that manages harsh lamp and motor loads.

Relays are switches that close and open electronically or electromechanically. Relays are managed when an electrical circuit opens and closes by the contact of another circuit. Relays are used when there is a need to manage a low-powered signal or only one signal. For example, relays were used for early computers and telephones. If you need something that requires higher power like electric motors, you will want to investigate getting a contactor instead of a relay.

These new relays were created for marine, defense, and aerospace applications. As a result, they were built for tough power switching and can handle large loads with a restrictive 35A/28Vdc load rate.

The TE Connectivity’s CII FC-335 series relays were created to meet MIL-PRF-6106 military standards. This means relays with this specification have the environmental and electrical requirements to be mounted on the structure of a missile, ship, aircraft, and other vehicles, directly. These requirements are needed to be able to use guidance and navigation systems, ground support equipment, power distribution, weapons systems, and fuel pumps.

Since relays both have a bundle across two contract pairs, they are made with double built contacts. This allows the relays a stable performance as well as less wear and tear.

Fun Facts:

  • Solder-sealed relays are said to be less stable than all-welded construction.
  • You can get these relays in terminal block configurations, 28Vdc coil configurations, solder hook configurations, and 115Vac coil configurations.
  • Relay Coils need a lot less current than most accessories.
  • A relay can act as multiple switches. That way you can deal with the complications of all the wiring where the relay is at instead of the having to deal with those devices from their specific locations.
  • Certain relays can be used to deal with radio frequencies, which makes the relay a form of an amplifier.

ultracapacitors

What are you going to do when it’s the dead of winter, and your power goes out? That electric fireplace is now useless as you try to scramble around the house to find enough blankets to keep everyone warm. What if you’re a principal of a school? The power goes out, so you must send all the kids home. As a result, you are losing a whole day of school and getting everyone behind. Instead of letting the weather or unfortunate events ruin your day try one of these new systems!

Power Supplies:

There are solutions to all these problems. Invest in a continual power system. Continual Power systems are equipment that gives emergency energy to a load when the main power source stops working.

In recent news, power supply interfacing BLOCK specialists came out with two new uninterruptible power supply units. The units, 24V/40A are DC input UPS that are made to provide reliable availability of safety in case of power failure. These power supplies can use capacitive energy storage or battery-power. The battery-powered UPS backs a diverse amount of different battery technologies which allows for total backup in case power failure. If there is a desired back up time, you can add extra battery packs.

Ultracapacitors are used in UPS units for effective and fast-moving coverage with only a minute lead time. Ultracapacitors are designed to operate like a capacitor and a battery. An ultracapacitor has the energy of a battery, but it does not run out or wear down as a battery does. Putting in extra batteries do not require maintenance since the ultracapacitors are built for a higher power density.

Maintenance costs on ultracapacitors are low since they have internal controls that monitor the temperature within the battery management system. They even have features that allow communication between the whole system and the requirements of Industry 4.0

stepper motor

A stepper motor is an electromechanical device that can convert electrical power into mechanical power. Stepper Motors are brushless and synchronous electrical motors that can split up a full rotation into a multiple number of steps. The position of the motor can be managed accurately without any feedback mechanism if the motor is attentively sized to the application. The theory of operation is used by the stepper motor. This theory makes the shaft of the motor turn an accurate distance when a pulse of electricity is supplied.

There are three main type of stepper motors: permanent magnet stepper, hybrid synchronous stepper, and variable reluctance stepper. Like its name, a permanent magnet stepper uses a permanent magnet in the rotor and operates on either the attraction or repulsion in the middle of the rotor permanent magnet and the stator electromagnets. The variable reluctance stepper involve a plain iron motor and runs on the idea that minimum reluctance takes place with minimum gap, thus the rotor points are captivated toward the stator magnet poles. The hybrid synchronous stepper, like its name, uses a mixture of permanent magnet and variable reluctance techniques to reach maximum power in a compact package size.

There are many advantages of stepper motors. These motors possess full torque even at standstill, are very reliable because no contact bushes are present in the motor (thus the lifespan of the motor is solely dependent on the life of the bearing), and the motor responds to digital input pulses, which provides open loop control which makes the motor easier and cheaper to control. The motor is also able to reach a low speed rotation that is synchronous along with a load that is coupled to the shaft.

Stepper motors also have different applications. They can be used in automotive gauges as well as machine tooling equipment’s. Surveillance equipment use stepper motors and they can also be used in the medical field for medical scanners and samplers and can also be found inside fluid pumps and respirators. Lastly, stepper motors can be used inside cameras for automatic focus and zoom functions.

Cyber Power Systems

A leading company in the power world, Cyber Power Systems, showed off its newest creation in the beginning of the year. CPS was founded in the mid-90’s and employees hundreds of people. They produce and carry a wide range of products from software, computer accessories, mobile additions and much more.

Their new product, the UPS, which stands for Uninterruptible Power Supply, is an ultra-secure system that is programmed to defend entire buildings from mass outages, security breaches, and random power surges. This protection ensures that important information is not lost, due to a fluctuation in power. UPS is the very first option that smart buildings have had when it comes to protecting their security data, smart energy information and important documents.

Not too much is known about the UPS because it has not been officially unveiled yet. UPS will be featured at the 2018 ASHRAE, American Society of Heating, Refrigerating and Air-Conditioning Engineers, Winter Conference, as well as at the AHR Expo.

This new product from Cyber Power System shows what the future will look like, and integration is everywhere. This is the first time a product can handle pulling information and protecting data from multiple pre-existing systems and has the ability to combine them to create a brand-new system that runs seamlessly. In the past, power spikes and surges were inevitable, and system wide black outs were basically inevitable due to the high amounts of power running across the ever-active grid. But now, with CPS’s new products, these concerns can stay in the past.

Microcontrollers

Microcontrollers, a small computer on a single integrated circuit, allow for input from sensors, and power LEDs to send signals to other devices over protocols. However, most microcontrollers do not have enough power alone to send signals to other devices. Thankfully, transistors exist and provide an excellent solution to higher power needs. First developed in 1922 by Julius Edgar, transistors weren’t given much thought until 1947 when physicists John Barden, William Shockley, and Walter Brattain use them to create a device while working at AT&T. This was one of the biggest milestones in technology history and transistors are now the modern building block of all computing devices.

There are many different versions of the transistor, but their main purpose is to take a small signal and amplify it between a pair of terminals known as the base, emitter and collector. There are numerous part numbers and they all have different voltage, currents and temperature ratings. The variety of transistors make it great because they can be used on a bunch of different projects, but it can be tricky to figure out which one you need.

There are several things you can accomplish with a microcontroller/transistor combination. Some examples include; the ability to power multi-colored LED strips, relay control for extreme loads, and amplifying audio. Amplifying audio is one of the most common examples of a transistor because of the transistor radio. Instead of vacuum tubes, transistors are now used to amplify audio signals. This change has allowed for radios to become portable, because it is only made of six components. It also allows for the use of MP3 players to Bluetooth to larger speakers. Transistors have really modernized todays world in several different aspects.

Heat Shrink or Cold Shrink Tubing

Although Heat Shrink and Cold Shrink tubing look almost identical from the surface, their internal characteristics are incredibly different. Each of the tubing has a different insulation technique, different applications, and different physical properties. The tubing can be for a variety of applications including but not limited to, splicing, terminating, and environmental seals. This kind of tubing is more cost effective and easier on the environment than most other similar tubing.

So, if these products are so similar how are they different? The most evident difference between Heat Shrink and Cold Shrink is the difference in how each one is applied. Heat shrink comes pre-stretched and has a sleeve. This sleeve requires a heat source for installation and cannot be installed without one. The polyolefin tubing is shrunk to its original size, creating a seal over the cable or joint. The polyolefin material in the heat shrink is more resistant to most chemicals and becomes extremely ridged once heated, making it a great option for mechanical protection. Heat shrinks tubing are ideal for use in industrial/commercial installations were operating temperatures are low and where chemical resistance is required.

Cold shrink also comes stretched over a removable plastic core, which allows for easy mobility on the application. The moving cote, and the tubing will contract, creating water tight seal around the connection or cable. Cold shrink is composed of silicone rubber, allowing for a greater UV resistance. This UV resistance allows for cold shrink to be used in exposed, outdoor environments. It also had an “active memory” allowing it to return to its original size and shape, no matter how far it was stretched. Also, Cold Shrink is more cost effective than Hot Shrink due to its ability to stretch without heat. The best way to decide what kind of tubing works for you is to assess the environment in which it will be used.
