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…

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…

The all new PISA-B multi-channel electronic circuit breakers help you to optimize the availability of your DC 24V systems right away and grow with your application. Protect Inform Secure Assist Selective tripping of overloaded channels In the event of a fault, PISA-B disconnects the affected channels only and ensures constant power supply to the remaining loads. This means individual faulty connections can be rapidly identified, isolated and rectified. Two different output types PISA-B features two types of output channels. Channel 1 and 2 are ideal for high capacitive loads up to 100mF and allow peak currents up to 12 A. Standard loads with up to 20mF can be connected to channels 3 to…
