Dan, in a past life I worked for a company that makes commercial ice cream makers like you would see in your local Dairy Queen, McDonalds, Burger King, etc. For India we had to include a UPS for some of our models because the power there would give us problems with the controls. I don't know the details but I do recall adding a UPS option to a newer model unit as recently as 3 yrs ago because of it.
The UPS took care of the problem for the manufacturer when I worked there.

Hope everyone is staying healthy and safe. I would like to know if anyone has experience with power quality issues in India related to damaging equipment and whether you find it is necessary to harden power supply designs specifically for India that you would not normally consider for other regions like the EU. From some reading on the topic there seem to be power quality issues but these are largely power interruptions and voltage sags that would temporarily cause the product to stop functioning but not result in the permanent damage of a global design. I have no recent experience with India but over a decade ago I do not recall having any issues with equipment in data centers, but perhaps they had facility power conditioning so the local building infrastructure prevented issues. Is the failure rate with typical consumer products higher in India because of power quality issues? Are extra precautions necessary? Thank you. ______________________________________________________ Dan Roman, N.C.E.
