Good morning Kai,

Yes the voltages goes as high as 295VAC and as low as 110VAC sometimes even 100VAC
Many times they run on Generater in that condition even this is not guranted & the worst case is I am not sure if the generators give 50Hz which standard in INDIA.

The SMPS for 85-260 is a standard but when we discussed with PI for a custom make SMPS they said it is posible to make SMPS from 85VAC to 300VAC.

As you said correctly the current required now is not above 2A (MAX) but we are planning to add a card reader (With Driver Card), Thermal printer (With Driver Card), and may be additional parallel LCD.

I know, now you will say what flow meter I am making.

It is a FUEL DISPENSING PUMP :-))))

http://www.midcopumps.com
is our website.
In MIDCO PRODUCTS you can see Electronics Pumps i.e MEB, Multi Dispensing Pumps & others.

In this there two products
1. MEB Midco Electronic Bullet
Single Product - Single Nozzle
2. MPD Multi Product Dispenser
3 Products (Max) - 6 Nozzles (Max)

I am making a SMPS for MEB

if you want I will attach or mail you the circuit which PI forwarded to me for my SMPS with 85VAC to 300VAC in & 5V 3A, 5V/4A & 12V/2A o/ps.
