AC / DC and DC / DC converters

AC/DC and DC/DC converters - key elements of electrical installations

Voltage converters are essential devices in many electrical systems.   They are used to change the parameters of electric current. In our offer you will find a wide selection of AC/DC and DC/DC converters. These devices allow you to adjust the voltage to the needs of specific receivers. They provide stable power supply and protection of sensitive components.

AC/DC converters convert alternating current to direct current. They are commonly used in power supplies for many electronic devices. DC/DC converters, on the other hand, change the value of the DC voltage. They are used in photovoltaic or automotive systems, among others.   In our daily practice we see a growing demand for these devices.

Types of AC/DC and DC/DC converters available at Onninen

Our offer includes various types of voltage converters. We offer models for both home and industrial applications. Devices with different power and output parameters are available. The most popular products include:

• DIN rail mount AC/DC converters
• DC/DC converters for photovoltaic systems
• Converters for vehicles and mobile machines
• High efficiency switching converters

We especially recommend converters of our own brands: Onnline and Fxa.   These devices are characterized by high quality of workmanship and attractive price. They were designed with the most popular applications in the electrical industry in mind.

How to choose the right AC/DC or DC/DC converter?

Choosing the right voltage converter is a key issue. It affects the efficiency and safety of the entire installation. When choosing, several important parameters should be taken into account:

• Converter output power
• Input and output voltage
• Device efficiency
• Protection (e.g. short circuit, overload)
• Working conditions (temperature, humidity)

Our experience shows that selecting a converter is often difficult for customers.   That is why we offer professional advice in this area. Our specialists will help you choose the optimal solution for a specific application.

It is worth remembering that the converter should have a power slightly higher than the sum of the power of the devices being powered. This will ensure stable operation and extend the life of the components. In the case of inductive loads (e.g. motors), the starting current should be taken into account.

We often come across the question about the difference between linear and switching converters. The former are simpler in construction and generate less interference. However, they are characterized by lower efficiency. Switching converters are more technologically advanced. They offer higher efficiency, but can introduce interference into the network.

Applications of AC/DC and DC/DC converters in practice

In our daily practice we observe a wide spectrum of applications of voltage converters.   These devices are essential in many industries and home applications. Here are some real-life examples:

Recently, we delivered AC/DC converters for a large logistics center project. They are used to power control and monitoring systems. They provide stable voltage for sensors and PLC controllers. Thanks to this, the entire installation operates reliably, which is crucial in logistics.

In the case of street lighting modernization in one of the cities, we used DC/DC converters. They enabled efficient use of energy from photovoltaic panels. The converters adjust the voltage from the panels to the requirements of modern LED luminaires. This solution significantly reduced the operating costs of lighting.

Many customers ask us about converters for campers and caravans. In this case, compact DC/DC converters are useful. They allow batteries to be charged from the car's alternator. They also provide stable power supply for 12V devices from on-board batteries.

Our experience shows that properly selected converters can significantly improve the efficiency of the installation.   That is why we always advise not to save on these key elements. Investing in a high-quality converter pays off in reliability and long service life.

At Onninen we offer not only the converters themselves, but also accessories for their installation. We offer protective pipes for running cables or actuator regulators. These elements allow for professional execution of the entire installation.

It is worth mentioning that voltage converters are also used in emergency power supply systems. In the event of a power grid failure, a DC/AC converter can convert the voltage from batteries to 230V alternating current. Such solutions are particularly important in facilities requiring continuous power supply.

Onninen recommends the use of comprehensive solutions that combine converters with other installation elements.   For example, in photovoltaic systems, DC/DC converters work together with inverters and charge controllers. This allows for optimal efficiency of the entire system.

When reorganizing offices, small AC/DC converters are most often needed. They are used to power office equipment such as routers or IP cameras. Our compact models are ideal for such applications.

In summary, AC/DC and DC/DC converters are key elements of modern electrical installations. Their correct selection and use translates into the efficiency and reliability of the entire system. At Onninen, we offer a wide selection of these devices, as well as expert advice. We invite you to contact our specialists who will help you choose the optimal solution for your needs.
