To make device installation and replacement as easy as possible for the users, we will answer some frequently asked questions regarding the challenges of high cut-in currents or so-called “inrush currents” in the following. "Inrush currents" occur in applications with inductive loads such as transformers and motors, but also in applications with switch mode power supply units.
[...] Read articleWhen it comes to overcurrent protection, the manufacturers of medical devices and systems often ask the following question: Fuse protection or resettable circuit breaker? The DIN EN 60601-1 medical device standard classifies both as permissible protection elements. However, the differences in practical application are considerable.
Read articleWhether remote access to systems or connecting employees working from home: In the age of digitisation, constant access to the internet is essential. The E-T-A Elektrotechnische Apparate GmbH ControlPlex® Rack power distribution system provides one of the key components for setting up stable communication networks.
Read articleE-T-A’s REX system is now approved for use in ATEX Zone 2 hazardous locations. It offers a wide range of modules for different applications. The system includes standard devices with signalling contacts and intelligent bus controllers for connecting superordinate control systems.
Read articleDC technology is the central future technology in many different areas. This also applies to busbar systems in the production plant and warehouse technology sectors.
Read articleDC technology is an important component for future applications. Further technological developments are necessary to successfully implement the energy transition. Switchgear that can keep up with these developments plays a central role.
Read articleThe EU has agreed on emission reduction targets according to which newly registered heavy utility vehicles should emit on average 15 % less CO2 in 2025 than in 2019.
Read articleAn increasing number of comfort functions in vehicles must be supplied with increased power. The obvious solution is to enable more power by increasing the operating voltage. The flowing current remains unchanged so that power loss, cable cross-sections and cooling systems must not be adapted.
Read articleHigher voltages for the active technology supply in the telecommunication technology area have been discussed for years. While existing systems are normally not retrofitted due to the high costs involved, this option is quite popular for newly built control rooms and data centres.
Read articleElectrical cars, buses and delivery vehicles are a common sight today. However, new solutions are needed to make them even more desirable and economical and appropriate for other applications, such as long-distance trucks and coaches.
