What does daisy chaining mean for power supplies?

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 as power supplies, are connected directly in parallel. This type of wiring is also referred to as "looping through". The English term “Daisy Chaining” is used colloquially, since the structure is vaguely reminiscent of a daisy chain. The principle can be used both to achieve a higher total current and to transmit analog signals or digital data. If…

Analysing backfeeding events with the help of power supply data

Backfeeding is a physical process that is highly desirable in many applications, such as electric vehicles, for the purpose of energy recovery. However, in an industrial setting, backfeeding can be a problem and lead to costly system downtimes if the power supply units fail. In this blog article you will learn how power supply data can help you to identify those backfeeding events and take measures. Resistance to backfeeding: why is it important for power supplies? Rotating machine components, such as drum motors, store kinetic energy which they feed back during braking in the form of voltage to the output of the power supply. On its output side, the power supply can absorb…

How do medical power supplies help protect patients and hospital staff?

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 to convert voltage as safely and efficiently as possible, while ensuring smooth operation over many years and in the tightest of spaces. Although this is a principle that applies to medical technology and to machine building alike, it is the industrial engineering segments where standard power supplies that meet these requirements are much more widespread. In turn, this…

DIN rail power supply units: How the service lifetime is determined by the temperature

As a system engineer, it is important to have a reliable and long-lasting power supply on which you can rely. Failure of the unit after a short time is annoying, costly and time consuming. Heat is the archenemy to long service life and reliability: The minimum lifetime of power supplies is determined by the lifetime of the electrolytic capacitors. The warmer it is, the faster the electrolytic capacitors dry out. Even a temperature rise of +10°C in the power supply cuts in half their service lifetime. In order to achieve the longest possible service lifetime for DIN rail power supplies, it is essential that the device is protected against overheating. The cooling concept…
