Hi,
I have a product in which 5v 2.5 amp adapter (input 230vac 0.2 amp max) used. The adapter is burning out sometimes usually when I connect it to the one of the phase (in 3 phase line where ac >30 hp motor is connected) carrying upto 50 amp current.
Now my question is why the adapters are burning? As per my knowledge the adapters cannot connect to a phase line which is carrying high current.
But I dont have any option, so planning to connect a high wattage resistor in series between the phase and adapter which will be acting as current limiting resistor. Is this method solve the issue? If this method is correct what resistor value (with wattage) need to be choosed.
Your help will be appreciated.
Thanks
