IEC

[rocoa]

¿Que tipo de IEC es este, sabeis si tiene alguna ventaja de conexion frente a los estandar actuales?.

Son lo IEC de 20 amp. y los montan algunos aparatos de reputadas marcas como Audio Research y Jeff Rowland (mi etapa de potencia utiliza ese conector). Obviamente el IEC del cable de red es también más grande.
La ventaja es que el contacto tiene mayor superficie.

Pues nada! al que le pueda interesar dicho IEC de 20 amperios... solo tiene que hacermelo saber. Por el momento yo no le puedo dar utilidd ninguna.

Este IEC me llego con un power-cord que compre en Estados Unidos, del cual no me fije mucho en su momento, pero bueno.. ahi esta!!

Recupero este hilo porque ya he dado con la respuesta:

How Electrical Safety Works in Grounded and Ungrounded Audio Equipment

There are two accepted ways of keeping people safe from the mains power. One is to connect all exposed metal to the mains safety earth, which is carried on the third prong of the mains plug. The alternative, depending on the particular country electrical code, is to ensure that all mains power connections, live and neutral, are isolated by at least two insulating layers, one of which may be air. Such equipment may have just a two prong power cable.

Double-insulated equipment is not connected to the mains earth and most of the HiFi and Video gear intended for the domestic user is double-insulated. In double-insulated gear the metal chassis is connected only to the "common" side of the circuitry to achieve some shielding to prevent RF interference from radiating into or out of the item. There can be no mains filters which connect to the chassis, so at least the chance of a shock from this cause is eliminated or at least minimised. It is easy to identify double-insulated equipment because the mains power lead will often be flat instead of round and the mains plug will only have two pins and there may also be a symbol on the chassis - two concentric squares. So what can go wrong with double-insulated gear? Plenty, as we shall now see.

En resumen: muchos equipos tienen doble aislamiento (Clase-II), con lo que no necesitan toma de tierra y funcionan perfectamente con tomas IEC de 2 y de 3 pines, porque el tercero (tierra) no lo utilizan.
