Hi guys,
Is there a reason why I can't use 3 x single phase SSRs (with an appropriate rating of course) with their "coil" sides in parallel to switch a bank of resistive heating elements in lieu of a single 3 phase SSR?
I'm reviewing an old circuit which was terribly un-balanced - anyway, the circuit is now fine, but budget is a factor (as is resistance to change by those building it, but that's another story). A single 3 phase SSR is expensive, but three of the single phase SSRs that they already use would (I think) do the job just as well at a fraction of the cost.
I can't think of any reasons why it would be a problem, but I have found it is always best to check.
Thanks in advance for any help you are able to offer,
...and merry Christmas
Thom
