Tom-
Thanks for writing.
Perhaps you could give me a little more info.
When you say to the transformer maker
"ICAS 50% duty cycle with maximum load period 5 minutes"
how does he translate this to core and wire size?
Also, how does this translate into the advertised specs for the amp.
I get real confused reading the manufacturers specs when
comparing amps. They seem to all use the same language
but it doesn't necessarily mean the same thing.
Thanks,
-bob

| I haven't seen a standard for ICAS. The rating difference is a DUTY
| CYCLE rating change, not a current rating change. In other words,
| if you draw 800 mA from a bridge you spec the transformer for 800
| mA dc load with a bridge rectifier and then say something like
| "ICAS 50% duty cycle with maximum load period 5 minutes". If
| you don't spec it in detail, the transformer will be underbuilt or
| overbuilt for some load conditions.
