In the search for a suitable power supply, the costs play a major role, alongside the technical requirements. The focus is often on the initial purchase price, while other potential costs that may be incurred during the operation of the power supply are not taken into consideration. In this blog post, we demonstrate why the […]
MTBF is the measure for the reliability of a device or system component. In this blog article you will learn what exactly is meant by MTBF, why it is an important quality indicator for power supplies and how it differs from service lifetime. The term MTBF appears in the data sheets of various technical system […]
For plant operators, the primary goal is to ensure maximum availability of machines and systems. This requires a reliable power supply throughout the entire lifetime of the system. Therefore, it is important that the applied power supplies are reliable, safe and durable. Within a power supply system, however, the power supply unit is often just […]
You are in need of a higher total power for your system or machine, or want to ensure a reliable power supply? Common solutions include the parallel connection or establishing a redundant power supply system. In this blog post, you will learn more about the definition, the differences and the correct use of both system […]
The colloquial term daisy chaining has established itself as a description for the direct connection of technical devices in series. In this blog article, you will learn what you should consider if you want to operate several power supplies in a daisy chain. Daisy chaining refers to a wiring scheme in which several devices, such […]
Manufacturers’ data sheets often only give blanket information on efficiency and power losses of their power supplies at different mains voltages or loads. Therefore, it is advisable for users to measure the efficiency of a power supply themselves. In this blog article, you will learn what you should pay attention to. Multimeter, wattmeter or power […]
In medical technology, the protection of patients and hospital staff has top priority. For this reason, medical power supplies are subject to strict requirements regarding safety, reliability and EMC. In this blog article you will find out how medical technology can benefit from the experience gained in machine building and system engineering. Power supplies have […]
Higher efficiency means less heat An essential factor for low heat generation in the power supply is, a high efficiency of the unit. The efficiency value describes the ratio of output power to input power of a power supply. The difference is converted into heat as loss. The advantage of high efficiency is obvious on […]
Derating is a protective measure which allows the use of power supplies at high temperatures, at high altitudes or in alternative mounting orientations. In this blog article you will learn what you should consider when it comes to derating. Most power supply manufacturers specify ratings for lifetime, output current, and reliability (e.g. MTBF) for their […]
A high inrush current is problematic for an efficient and simplified system design. Therefore power supply manufacturers try to keep AC inrush as low as possible. In this blog article you will learn why inrush current occurs in power supplies and which methods manufacturers apply to minimize it. Probably most of us already have noticed […]
