Economic Flat Design (EFD) power transformer cores offer a signifi cant advance in circuit miniaturization. Their low build height and high throughput power-density make them ideally suited to applications where space is at a premium. Throughput power of a ferrite core transformer is essentially proportional to its volume. So the transformer is one of the main limitations in a DC-DC converter's size. Now, with the introduction of the EFD system, a signifi cant reduction in transformer core height has been achieved. EFD transformer cores combine both extreme fl atness with a very high throughput power-density for frequencies up to 1 MHz and higher. Every transformer, based on the EFD range, has a lower building height than any other existing low-profi le design with the same magnetic volume. This is achieved by placing the centre pole of the core always in the centre of the fi nished transformer, thus making maximum use of the winding area.
The PH core range consists of potcore halves specially designed for use in proximity switches. Their shape is derived from the IEC standard P-core range. Outside diameters are adapted to fi t standardized sizes of proximity switch housings. Since the cores are used as halves, their height is increased to accommodate the winding. A complete range of coil formers is available.
The EP/LP core range was specially designed for wideband transformer applications where low build height is a must. The board area occupied by the assembly is almost a square, allowing high packing densities on the PCB. The bobbins have two rows of pins allowing easy design of multiple output transformers. Cores are available in high permeability materials, including the new low THD material 3E55, for wide band transformers and in power materials for small power transformers.

Eddy-current testing (also commonly seen as eddy current testing and ECT) is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of electromagnetic induction to detect and characterize surface and sub-surface flaws in conductive materials. The two major applications of eddy current testing are surface inspection and tubing inspections. Surface inspection is used extensively in the aerospace industry, but also in the petrochemical industry. The technique is very sensitive and can detect tight cracks. Surface inspection can be performed both on ferromagnetic and non-ferromagnetic materials

three phase double winding amorphous alloy transformer - Extremely Low Loss, Energy-Saving Features, High Power Consuming Efficiency; ã??ã??- Amorphous Metal Materials are advantageous in that: They just need to consume lesser energy in material manufacture and with their extremely low losses, power is saved in a large sum, thereby greatly reducing the power plant output, or relatively lowering waste gas (CO2, SO2) emission, lessening both environmental pollution and greenhouse effects, and realizing a maintenance free and contamination free state; ã??ã??- Low in Operating Temperature, Tardy in Insulation Aging, and Long in Transformer Life; ã??ã??- High Overload Capacity, High Mechanical Strength; ã??ã??- Amorphous Cores are featured in that: When a magnetic flux pass through amorphous cores in a rather high frequency, these amorphous cores may remain a low iron loss and a low exciting current, which may not result in core saturation. Consequently SBH15 amorphous alloy transformers made from amorphous cores possess a rather fine resistance to harmonic waves; ã??ã??- Rapid Investment Recovery
