Russell: This is the right group. We have an opinion on everything. Power factor is tied up with the complex subject of power quality and low frequency emissions. The US controls this on a facility basis with IEEE 519 and in Europe it is controlled by the EMC Directive under EN 61000-3-2. This means it is on a product basis.
In Europe the control is down to 25 Watts if a luminary and 50 Watts for all other products. There is an EMC workshop starting tomorrow at the Sheraton at the BWI airport where two days is going to be devoted to this subject.

I know that with the increase in power supplies that convert the AC voltage to DC there has been an increase in concern for keeping the power factor of the instrument close to unity. Is this a power utility problem or does it also apply to the small electronic instrument? Are the standards the same in the US and Europe and other countries? What are the standards? Do they apply to all equipment? Thanks in advance for any information. Best Regards, -------------------------------------------------- Russell Anderson Campbell Scientific, Inc.
