Hi folks,
I have the following problem and I wonder if somebody can give me some clue.
On my electronic board I have an AC/DC converter with the following specifications.
Max. input voltage = 277 volt
Max. input current = 70-80 mA
Freq. = 60 HZ
However my input voltages vary from 120 to 600 volt.
What comes to my mind is to have a self adjuster circuit to detects the voltages below the 277 volt and let them pass through and adjust the higher voltage. For such purpose I believe that I need a step down transformer or a clamper circuit. But I have no idea if this is feasible or not!
On the other hand, I may better to have 2 voltage converters. (As I searched in the market there is no AC/DC converter in a wide range of 0-600 volt) One gives 90-290 volt and the other 300-600 volt. However, I need to have a device maybe a relay or so to detects if the voltage is below 277 or not.
In total, what do you think and in your opinion how do you guys solve such problem?
Thank you in advance.
P.S. The photo attached gives you a rough idea of what I think.
