Hello to all,
by mistake we ordered and got delivered el. magnetic valve with AC 24V coil but we have only 24 V DC voltage. I know that if we try to connect DC voltage to AC coil it is very probable that we'll burn out the windings. I know that using resistor is also a bit tricky because in that case we cannot be sure if coil will work always as intended.
I was thinking to try something like this:
I'll measure ohm resistance of this AC coil and use resistor of about the same resistance in series. This way I'll limit the current that can damage the coil. And then I would connect electrolytic capacitor in parallel with this resistance. My idea is that during initial loading higher current will pass to the coil causing it to react and then capacitor will block the DC current so all current will flow through resistor. When 24 VDC disappears, capacitor will burn its energy on resistor and AC coil will de-energize.
Will this work? Is here any danger to damage something?
What do you think about this improvisation?
I need to say that due to the limit time we cannot wait for DC coil to be delivered.
Thank you
