The new current transformers from MAGNETEC, featuring NANOPERM® alloy core for high-precision readings plus improved tamper-proofing, can be combined with MAGNETEC’s magnetic shielding designs to form an ideal system solution for a broad range of anti tampering metering applications. The combined advanced features of both current transformer and adapted magnetic shielding offer a so far …
It is one of the most up-to-date topics within the Solar Power Industry to improve the efficiency of that complex process of energy conversion. Every single tenth of a percent is welcome – although > 90 % is already state-of-the art for modern DC/AC converters. Following this target, more and more producers of photovoltaic inverters …
For AC-type RCCBs that are sensitive to sinus exciting currents, toroidal cores made of Permalloy-type materials are used for decades. The application of nanocrystalline alloy NANOPERM in RCCBs were limited to a region where the special annealing cycle leads to flat or round ferromagnetic hysteresis loop with a remanence ratio smaller than 0,7 with a …
So far, nanocrystalline cores could not be used in applications with significant DC preload because they saturate early due to their high permeability level (> 18,000), which gives only an advantage in non DC applications. MAGNETEC now offers high saturation cores which enter into a low permeability range of typically 2,000 – 8,000 which was …
The new COOL BLUE range completes MAGNETEC’s series of high performance toroids made from the nano-crystalline material NANOPERM. Available are cores up to 500 mm (!) outer diameter and several space saving stadium-shaped (oval) variants. The cores of the new series feature significantly improved high frequency performance due to a permeability level several times higher …
