We’ve expanded our P0584/85NL high isolation gate drive transformer line with the new –ANL series.

This new series uses insulation wire on all windings, making them compliant to safety agency standards such as IEC61558 and IEC60601 for reinforced isolation. The P0584/85NL series provides isolation in MOSFET and IGBT drivers in industrial applications such as motor drive circuits and solar inverters and for power supplies for a range of medical devices. The P0584/85ANL versions extend these to applications that require higher levels of safety and isolation with 30% increased isolation capability (to 4250Vrms) and 20% greater volts-sec capability.

Gerard Healy, Product Manager for Pulse Electronics Power Business Unit, explained:

“Existing toroidal gate drive transformers with triple insulated Teflon wire on just one winding are not compliant to certain safety standards which require mechanical support between windings, even when triple insulated wire is used on one winding. Pulse’s new P0584/85ANL series uses insulated wires on all windings, making them fully compliant. In addition, by using smaller wire diameters, Pulse can increase the number of turns to increase volt-second capability within the same platform size.”

P058xxANL Key Features

Our P0584/85ANL series expand our line of P0584/85NL high isolation gate drive transformers to offer higher isolation capabilities. They come in a robust package with 8mm creepage distance. The transformers are RoHS compliant and meet standard EIA481 requirements. P0584/85NL are UL recognized/TUV certified to IEC 60950 while the –ANL versions are compliant with the requirements of IEC 61558 and IEC 60601 for reinforced insulation. They are available in tube packaging.
