Embedded power supplies are key components in many electrical and electronic systems.   At Onninen we offer a wide range of these devices. Our products are characterized by high quality and reliability. We provide solutions tailored to the various needs of our customers. From small projects to large industrial installations.

Our offer includes power supplies from renowned brands. Among them, Mean Well, F&F and MPL Power stand out. Each of these companies has an established position on the market. They guarantee reliable operation and long product life. Thanks to this, our customers can be sure of the quality of the devices purchased.

Types of built-in power supplies available at Onninen

The range of built-in power supplies in our wholesaler is very wide. It includes various types of devices, adapted to specific requirements. Here are the main categories of products available in our offer:

• Modular power supplies
• Built-in power supplies
• Switching power supplies
• Bridge rectifiers

Modular power supplies are a popular solution in many installations.   They are characterized by compact dimensions. They are easy to install in control cabinets or switchboards. Thanks to their modular design, they can be easily expanded. This flexible solution works well in various applications.

Built-in power supplies are designed for installation inside devices. They are small and have efficient cooling. They are often used in electronic equipment and industrial automation. Their design allows for optimal use of space in housings.

Switched-mode power supplies are characterized by high energy efficiency.   This translates into lower energy losses and lower operating costs. These devices are lightweight and compact. They are used in many modern electronic systems. From simple devices to advanced industrial installations.

Bridge rectifiers are essential elements in many power supply systems. They are used to convert alternating current to direct current. Our offer includes bridges with various parameters. We select them depending on the power and voltage in a given application.

How to choose the right built-in power supply?

Choosing the right built-in power supply is crucial for the correct operation of the system. At Onninen, we often come across questions on this topic. Here are the most important criteria to consider:

• Power Supply Output Power
• Input and output voltage
• Mounting type (DIN rail, enclosure, etc.)
• Dimensions and weight of the device
• Energy efficiency
• Protection (overload, short circuit, thermal)

Output power is one of the key parameters when selecting a power supply.   It must be properly matched to the load. Too little power can lead to unstable system operation. On the other hand, oversizing the power supply increases costs and can reduce efficiency.

The input and output voltage must be in accordance with the requirements of the installation. Our offer includes power supplies with various parameters. Thanks to this, we can select the right device for a specific application. We take into account the specifics of a given project.

The type of mounting is important due to the place where the power supply is installed. DIN rail power supplies are popular in switchboards. Built-in models are used inside devices. Dimensions and weight are important when the mounting space is limited.

Energy efficiency affects operating costs and generated heat.   Modern switching power supplies achieve high efficiency. This translates into lower energy consumption and lower thermal load. This is especially important in the case of long-term operation of devices.

The protections protect the power supply and connected devices from damage. Our offer includes models with different types of protections. We select them depending on the specifics of a given application. This ensures safe and reliable operation of the entire system.

Examples of applications for built-in power supplies

In everyday practice, we encounter a variety of applications for built-in power supplies. Here are some typical examples:

In industrial automation, these power supplies are an essential element of control cabinets.   They provide stable power supply for PLC controllers, sensors and other devices. We recently implemented a project for a large production plant. We used Mean Well modular power supplies for DIN rail. Their compact dimensions allowed for optimal use of space in the switchboard.

In monitoring and access control systems, built-in power supplies are crucial. They ensure uninterrupted operation of cameras and card readers. In one of our recent projects for an office building, we used MPL Power switching power supplies. Their high efficiency translated into lower system operating costs.

In LED lighting, built-in power supplies are often used in luminaires.   They provide the appropriate current parameters for the diodes. In the project of the building facade illumination, we used F&F power supplies. Their small dimensions allowed for discreet installation in lighting fixtures.

In medical devices, power supply reliability is critical. That's why we use the highest quality power supplies. In a recent project for a clinic, we used Mean Well medically certified power supplies. They provided stable and safe power for sensitive diagnostic equipment.

At Onninen we have extensive experience in the selection of built-in power supplies. Our specialists will be happy to help you choose the optimal solution. Please contact us and take advantage of our technical knowledge. Together we will find the best solution for your project.
