Hi Alan,
Firstly i ordered the fortron groups psu (3 units , all for my own use) without checking the details as i know the quality of your products.
about the input filteration, let me put it this way the quality of power in about 95% of our country is very "Dirty".
Brownouts and Surges are the norms. most of our industrial units and sub-stations do not have adequate or appropiate power factor correction capacitors and since our electric grid is interconnected the input mains power is extremely "jerky". sagging or brownout is more prevalent then over-Voltage. voltage droping to 200V AC or less is very common for extended period of time.
Not only the voltage varies a lot but the frequency (rated 50 Hz) varies a lot too.
Also most of us use our m/c's at an ambient average temp of 35C to 38C. with high humidity to make the matters worse. and many of the users do not have proper "earthing / grounding" of the mains power lines.
NB: the power position in cities like Banglore, Delhi, Chennai, Pune etc... is comparitively and relatively good. i am based in Mumbai where the power position is world class. but the vast majority of our people live in semi-urban and rural areas where lies the future world market for pc hardware. (just like in China).
Hence the quality of the X2 rated input filter caps, and the coils, surge supressors should be extra heavy duty for Indian sub continent. regulation and post regulation components you guys are the best judge and am sure you would be using the top rated parts as the name and reputation you have earned proves that.
The reason i am posting this long post is that we need good quality psu's in our country, especially for fast rising enthusiast community. We do not want you to be just satisfied by these small , sample orders. but we want you to be a bigplayer in the main stream indian market. How you achieve that is ur co's business policy but you should not ignore a market potentially 2~3 times bigger than Europe.
