DC CONVERTERS – WHAT ARE THEY AND WHAT ARE THEIR FUNCTIONS?
Voltage converters can decrease or increase the output voltage in relation to the input voltage. By alternately turning on and off the voltage with high frequency, they control the value of output voltage without causing any disturbance in the work of the device.

What does it mean in practice and what are the benefits of it? Let us look at an example. Imagine we want to power up a device with a rated voltage of 6V. However, we only have a car battery that provides 12V DC. In this case, a converter would allow us to safely turn on the device by adjusting and lowering the value of the voltage. This type of a converter is called a step-down converter. Similarly, in order to power up a device that requires higher voltage, the converter will raise this value, while maintaining the appropriate parameters. Here, we are talking about a step-up converter. There are also more advanced converters which can both lower and raise the voltage as needed.

Recom DC/DC converters

Highest quality – Recom DC/DC converters

Years of experience and the thoroughly developed technology makes it possible for Recom to produce reliable, high-quality products that are also safe for users. The company owns advanced laboratories located in, for example, Austria, thus allowing for the continuous improvement of DC/DC converters and putting new solutions on the market. Recom products are used in such crucial branches as power generation and railway industry. They are also useful in medicine and automotive industry, especially when it comes to e-mobility solutions and new, related technologies. Using their knowledge, Recom is currently expanding their business to include AC/DC power supplies (with the power of up to few dozen kW) and LED drivers.

Recom DC/DC converters – key technical parameters

One of the flagship devices from Recom are R-78 DC/DC converters. The specific parameters of the converters from this series differ, allowing the users to choose ones that will suit their needs. Taking into account the full range of capabilities of DC/DC converters, these are the most important technical parameters:

  • Power 180mW – 30W.
  • Input voltage from 0.65 to even 72V, each device allowing for a certain input voltage deviation, and so e.g. in the R-781.8-1.0 converter this deviation can be around 4.75÷18V.
  • Output voltage which, unlike the supply voltage, is a constant value with no interruptions. Here, the voltage varies around 1.2÷24VDC.
  • Device efficiency – power transmission, especially through intermediary devices, comes with certain energy losses. In the case of voltage converters, energy losses in the form of generated heat are particularly important. The efficiency, meaning the output to input power ratio in the products described, declared by the producer reaches up to 97%. This parameter proves that Recom devices are flawlessly designed when it comes to energy losses and allow for highly effective work of the converters.
  • The converters in this series work in three temperature ranges – from -40°C to 70°C, 85°C or even 100°C.
  • Recom converters have a short-circuit protection. They are safe both for the user and the whole power system.
Use of DC/DC converters

Only few people know how many different applications these devices may have. Often, the work of a complicated electronic assembly would not be possible without them. Then, where can we find them and what role do they play?

Nowadays, very popular devices that use DC/DC converters are solar panels. Because of the changing weather conditions throughout the day, the production of electricity by the photovoltaic array oscillates within a very wide range, causing output voltage fluctuations. A converter can also help in this case, as it stabilizes the output voltage before supplying the energy back to the grid. Besides, all the battery-powered devices, with voltage that is different than the output voltage of the battery, are supported by voltage converters.

Summary

All these examples show how important DC/DC converters are for the proper functioning of various devices. In fact, it would be hard to imagine a contemporary device without them. DC/DC converters convert the unstable input signal and prepare it to work with a device that requires a constant voltage with no interruptions. They can lower or increase its value within the range set by the manufacturer. The wide range of highest quality products offered by Recom will satisfy the needs of the most demanding electronic circuits. Many years of recognition from clients from all over the world are the best evidence for that.

Recom converters offer


SWITCHES FROM E-SWITCH – A NEW MANUFACTURER
E-Switch is an American brand that specialises in all kinds of switches. Their wide range of products includes basic components like TACT switches, but also high-current switches, DIP-switches, ignition switches, touch buttons, trigger buttons and many other solutions.

DC CONVERTERS – WHAT ARE THEY AND WHAT ARE THEIR FUNCTIONS?
Voltage converters can decrease or increase the output voltage in relation to the input voltage. By alternately turning on and off the voltage with high frequency, they control the value of output voltage without causing any disturbance in the work of the device.

ARDUINO – COMMUNICATION USING THE ETHERNET NETWORK
For many years, the creation of extensive computer networks has ceased to serve only for connecting computers.

Wireless communication in IoT systems using Arduino MKR modules
One of the biggest problems currently facing the Internet of Things (IoT) devices market is its high fragmentation. The multitude of devices and communication protocols makes it very difficult to build a uniform and functional system if you decide to use components from different manufacturers.

VELCRO® PRODUCTS NOW AVAILABLE AT TME
The TME offer has been expanded by products of the world-famous Velcro® brand. Velcro® was founded in 1951 and quickly became a dominant supplier of fastening solutions in a wide variety of industries. The company's offices are located in America, Asia, Europe, and Africa. The first Velcro® factory, opened in Manchester in 1957, is still there.

INFRARED LEDS IN SMD PACKAGES
The TME catalogue includes a wide range of infrared LEDs. The noticeable market trend in favour of the miniaturisation of devices forces manufacturers to search for solutions combining high power (ca. 1W) with a small size of SMD components. For this reason, today we present one of such solutions: PK2S-series IR LEDs, which are the smallest SMD power diodes offered by ProLight.

NKK SWITCHES - QUALITY AND FUNCTIONALITY
Switches are electromechanical components that control the current flow by connecting and disconnecting the electrical circuit. Even the popularity of touch screens has not changed the fact that it is still the leading method of user-device interaction.

KEMET FERRITE PLATES
Today, electric vehicles are becoming increasingly popular. Electric motors are gradually replacing traditional internal combustion engines, and in the future we will see more and more electric vehicles on the streets.

ORNO - OR-WAT-419 Power Meter [electricity consumption calculator]
In brief, wattmeters tend to operate by measuring continuously instantaneous voltage (volts) and current (amperes) to give accurate information of energy units used, expressed usually in KWh.

UNIVERSAL AND RAILWAY DC/DC CONVERTERS
Traco Power is one of the leading manufacturers of DC/DC converters. Their DC/DC converters are designed for the most demanding industry sectors, including the railway industry. There are numerous railway industry safety standards. They concern not only the mechanics of rail vehicles, but also many design aspects. Appropriate certification is required, among others, for electric train components.

ETHERLINE® LAN CAT.6A PATCHCORDS BY LAPP
TME’s offer now includes ETHERLINE® LAN CAT.6A patchcords by LAPP. The series is designed for applications where reliability and safety are of utmost importance. With high resistance to electromagnetic interference and harsh environmental conditions, the products are intended for demanding industrial and commercial applications. The patchcords are designed with user safety in mind, which is confirmed by the renowned UL (Underwriters Laboratories) certification.

PCB – GET READY FOR WORK WITH A PRINTED-CIRCUIT BOARD
Printed-circuit boards (PCB) can be found in each electronic device. They accommodate all necessary elements. They are connected via copper tracks protected from external conditions (such as oxidation) by a “solder mask”. Printed-circuit boards can be made of various materials, although the most commonly used solution is the PCB laminate comprising fibreglass and cured with epoxy resin. Such boards can be cut to various shapes and sizes.
