I recently came across some solenoids in the field that used 120V AC primary input and then rectified voltage to DC for use with a DC coil in the solenoid.
What is the point of rectifying voltage to DC? Why not just have an AC rated coil in the solenoid?
Would DC coil have a larger impedance and therefore require less current when reflected on AC?
