A compact noise filter for large equipment accommodates currents as large as 100 A or more because it incorporates flat, vertically wound copper wire. Samples will be available in October. To wind the straight copper wire, the engineers used an automatic winder, creating double coils adjacent to each other. This raises the density of the electromagnetic coupling and results in 5-to-10-fold improvements in the current super-position characteristics of inductance. For easy assembly, the coil combines with UU or UI ferrite cores. Offering voltage rating for AC 250 V single-phrase or AC 450 V triple-phase, the filters attain a current rating of 50 to 150 A. The 80 A version measures 150 €240 €90 mm.

Conductors are materials having a low resistance so that current easily passes through them. The lower the resistance of the material, the more current can pass through it.
The most common conductors are metals. Silver and copper are the best of them. The advantage of copper is that it is much cheaper than silver. Thus copper is widely used to produce wire conductors. One of the common functions of wire conductors is to connect a voltage source to a load resistance. Since copper wire conductors have a very low resistance a minimum voltage drop is produced in them. Thus, all of the applied voltage can produce current in the load resistance.

Successfully diminishing the difference between the effective permeability and the initial permeability in a practical core, the H5C3 ferrite core material provides an excellent permeability reaching 13,000. This enables drops in size. The material is at work in the EP-style core. During manufacturing, sinter technology minutely controls the crystal structure of the H5C3 while maintaining excellent frequency characteristics. The H5C3 material has excellent temperature characteristics with a temperature coefficient of -0,5 to 1,5 (-30 ± 70˚C), improves the frequency characteristics in the high and low bands, reduces the insertion loss and operates in the temperature range of 0˚ to 40˚C.

To protect an IC from static surge invasion, the Emi Guard electromagnetic interference (EMI) filter provides a surge-absorbing function. Use of a proprietary three-terminal capacitor structure for the varistor allows it to absorb the static surge that invades the I/O pins of a semiconductor IC; this prevents IC destruction. ICs that static surges of 1 kV normally destroy will withstand static surges of 15 kV. The filter provides a static capacity of 130 pF + 20 per cent (at 1 kHz), a DC resistance of 200 to 500, a rated voltage of dc 25 V, a rated current of DC 20 mA, a surge withstanding current of 15 A (twice in 8/20 µs) and operating temperature range of – 25 to 85˚C.

A phase monitoring relay which ignores momentary voltage or phase failure has been launched by Carlo Gavazzi Electromatic.
Designated the Electromatic S-System Type 5074, the relay was developed as a result of frustrations in the British water industry where monitoring relays had the costly and annoying feature of switching alarms or shutting down equipment when a mere momentary loss or reduction in voltage of a phase was detected. The Electromatic solution has been to build a delay on de-energise timer into the relay unit so that a 10 second delay is experienced before the relay points release.
