i want to make reverse polarity protection without voltage drop ,i was searching and i found this
now , i want to size this relay .
load ( 30 A , 48 V ) 1440 Watt
Does load ( normally closed ) matters with relay?
Where load is normally closed so relay is not operated when power supply is connected correctly.
so if that right then
Does relay ( 12 V , 5 A ) 60 Watt can do the work ?
if all above right , then the load will taken into concern is when relay energized so the led ( in photo above ) and resistor here will be loads .
Thanks you .
