Components for

Power Conversion ETD /EER-Series

Components of the ETD-Series andEER-Series are on-devel opments ofthe well known EC-range. Theyhave been devel oped specially forconverters in switch-mode powersupplies.

We can supply coilformers made inhigh quality thermoplastics, matchingyour production require ments. Accessories, such as potting boxes,safety class spacers and clips, arealso included in this catalogue.

All dimensions in mm/inch. The permissible deviations according toDIN 16901 apply as tolerances.

Wherever high-temperature soldering processes are used inconnection with ETD/EER-Seriescoil formers, we recommend irradiation cross-linked plastics. This ensures that the mechanicalproperties – in particular those of gfr-polyamides – are maintained and breakages are reduced. For this reason NORWE offers all plasticcomponents of the ETD/EER-Seriesin irradiated cross-linked materials.

In the short term, the cross-linkedmaterials can be exposed to veryhigh temperatures. Apart fromimproved aspects in productionthere may be interesting costadvantages, and a discussion withus could be useful.

Should you need further assistance,be it technical or to assist whenplacing your order, we look forwardto hearing from you.

Fully tagged or pinned coilformersare – in small quantities – usuallyavailable from stock. We can alsoquote for coilformers with pins ortags fitted to your requirements. All lead-times are relatively short.

Our extensive range of modular tooling allows almost unlimited constructional changes to meetcustomers specification, often bysimple changes of tool inserts.

In addition the modular tooling system allows extremely short tooling times and can be very costeffective.

This catalogue contains information on all productsof the ETD-Series and EER-Series.

ETD Standard with Solder-Pinsand Side-Wrapping Pins(horizontal and vertical)A well-established design and –resulting there of – optimum features in the further processingcharacterize this solid series. All coilformers are suitable for automatic winding on computercontrolled machines. They featurestand-offs on the pcb-side, thus reducing solder problems.

The coilformers with side-wrappingpins have U-shaped terminals.This allows automatic binding-onof the wires, and after solderingleaves the pcb-side of the terminalclean and free from tin.

ETD lr CoilformersThe ETD-Series lr is a completelynew design from NORWE. The coilformers feature a reducedweight and also a minimized overallheight. Special winding noses anda new wire routing provide tension-relief when binding on the wire. The coilformers are due to their optimized design very attractivewith regard to technical and alsoeconomical aspects.

EER CoilformersThe coilformer series is a com pletelynew design from NORWE and features a reduced weight and alsoa minimized overall height. TheEER-coilformers for power conver-sion are very well suitable for compact windings with low leakageinductance.The design allows automatic wind ingalso on NC winding machines. The round inner core is suitable forthe use of thick wires or strips.The coilformers have stand offs toavoid cold-solder joints to the pcb.

ETD Standard with Solder-TagsFrom the technical point of view this series is very solid and well-established and convinces by optimum characteristics in the further processing. The coilformers are suitable for automatic winding on computercontrolled machines. Side-wrapping and soldering, including thick wires and litz wires,does not distort tag positions in the grid and leaves the undersidefree from tin.

ETD Safety Class with Spacers DR Clearance and creepage dimensionsfor safety-insulated componentsmay vary from country to country. Accordingly, test voltages of 2500/4000/7500 V between primary andsecondary and to the core requirecreepages and clea rances from 4 to 12 mm (0.157 to 0.472 inch).

Spacers DR are advantageous forthese applications. Examples areshown in the drawings below. Insulating tape between separatewindings (across the total widthincluding spacers) is required toachieve creepage and clearancedimensions.

With spacers DR on both sides ofthe winding creepage and clearancedistances of 8 or 12 mm (0.315 or0.472 inch) can be achieved.

With spacers DR only on one or theother side of the winding creepageand clearance distances of 4 or 6 mm (0.157 or 0.236 inch) can beachieved.

Irradiation Cross-Linking of ETD/EER Components

NORWE cannot only look back on more than 40 years of experience in the development and production of coilformers but has in the meantime also gained almost 10 years of experience in irradiation cross-linking.

All components of the ETD/EER-series can on request be supplied in cross-linked material. A cross-linkingenhancing material is added to the thermoplast granulates. After moulding the components are irradiated withBeta- or Gamma rays – depending on the penetration required.The material loses its thermoplast characteristics (but it is not a thermoset) and withstands very high tempe ra -ture peeks for short periods without any problems.

● Depending on the degree of cross-linking the coilformers and accessories withstand solder temperatures of450–480°C for about 1–3 seconds. Irradiated cross-linked components easily tolerate the higher solder tem -peratures required due to the contact elements being changed to be leadfree.

● Unlike high temperature polymers – also cost-effective granulates are suitable for irradiation cross-linking. The characteristic features of the coilformers and accessories do not change due to the cross-linking.

● In contrast to high temperature polymers lower temperatures of material and mould during the production process are required and thus the tool elements are less stressed resulting in longevity.The lower temperature profiles during the moulding process provide a lower wear and tear of the tool elementsas well as a perceptible saving of energy costs.
