E-T-A to power feed active systems in OpenRAN
The new Radio Network, OpenRAN, has caused a lot of discussion as a upcoming future technology of radio networks.
Condition Monitoring for DC 24 V circuits and power distribution
The fourth industrial revolution is particularly moving the mechanical engineering industry. The constant goal is to increase machine availability and output by means of digitalization. To this end, a particularly large number of resources are being invested in targeted data acquisition, smart services, and special condition monitoring systems for an optimized remote maintenance and servicing strategy....
Electrification with the 48-volt on-board electrical system requires special protection
The 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.
A reasonable possibility to save fuel is the partial electrification with a 48-volt on-board electrical system, which is already taking place in modern passenger cars...
Industrie 4.0 – Condition Monitoring and Predictive Maintenance
Storage and evaluation of all data logged in machinery and plants is the precondition for solutions on the score of “condition monitoring” and also “predictive maintenance”. Plant transparency is significantly enhanced through the consistency within the systems - always aiming at increasing the system availability...
Reliable power safety of UPS units (AC230V)
UPS means “uninterruptible power supply”. These systems are used to ensure permanent power supply even in the event of a mains failure.
The current dilemma is: The current supplied by the UPS is not sufficient to magnetically trip the overcurrent protection. Hence, the entire UPS system will be disconnected. The so-called “uninterruptible power supply” will interrupt ...
Reliable electrical medical equipment and machines
Reliable electrical medical equipment and machines is the basic requirement for successful work in the operating rooms, on the wards or also in the laboratories. Safety and quality must not be compromised. This is particularly true for the protection of devices and machines in the event of overcurrents.
E-T-A’s circuit breaker/switch combinations reliably disconnect hazardous overcurrents...
SCR® technology: What are the risks of using mechanical battery master switches?
With the implementation of the exhaust emission standard Tier 4 final or EURO 6 for diesel engines in off-highway vehicles, the SCR® technology has made its debut.
Selective catalytic reduction (SCR) takes place by injecting the AdBlue® preparation into the exhaust gas stream. Nitrogen oxides and ammonia react to water and also to nitrogen....
Chemical plants: Planning tool for simulating a load circuit
Electrical systems in the chemical and pharmaceutical industry often have long load lines, a DC 24 V supply and many loads supplied by one source. In addition, there are often problems with selective trip in the event of a short circuit at the load.
E-T-A supports the planning process with a simple calculation tool to realise the best possible selection of the correctly rated circuit breakers. Additionally, we offer suitable power distribution systems...
