Never used 'em before. Other than having high values for their size, don't know much about them. Just curious about your opinions.
Thanks!
Thanks!
11.7 mA is the steady-state current. Kick-in current is the combination of the inductor kick-in current, which is zero, and the magnetization current, that is unspecified.boji said:I think the equation is C=I*t/U.
TQ2-12 draws 11.7mA. * 12 relays = .14 Amps
So, 0.14 A * .5 seconds / 12v = .00583 or 5800uF
I figured half a second is more than enough time for a relay coil to energize so 2200uF would be ok.
Quite right, thanks for pointing that out.11.7 mA is the steady-state current.
Nice. I've been at the soldering station in the evenings for what feels like three months straight. Now I have an excuse to learn this little 2ch LeCroy scope my brother gave me.Kick-in current is the combination of the inductor...and magnetization current.. Trial-and-error is de rigueur.
Lucky you!boji said:this little 2ch LeCroy scope my brother gave me.
Yes, thanks Benb. I've decided to use standard polar lytics for buffering. They should do the do.Be sure to read [super capacitor] specs carefully, specifically the equivalent series resistance and the max current you can get out of it.
Shoot... Not to apple-polish too much, but I feel luckiest of all for the gifts of advice I've been given around here over the years ... 8) :-*Lucky you!
Hello NM,What is the psu / voltage source for the relay coil voltage ?

Dedicated 12v out from an old 600w Wheatstone broadcast desk PSU, or possibly a nos Amek big44 SMPS.
