I have 208 VAC coil voltage relay that I want to operate with 240 VAC. Can I drop the voltage down with a capacitor? If so what value? Should the capacitor be rated for 370 VAC? I don't know the impedance of the coil. Can I find it with a meter?
If C1,C2 are capacitors,
Vin----- | = C1 | o-------Vout | = C2 | _ COM
Vout = Vin *C1/(C1+C2)
208/240 = 86/(86+14)Can I do it with an 860mfd capacitor and a 140mfd capacitor? Should they be rated for 370 volts?
