Hi,
Regarding our axial-flux controllers & protection scheme...
One detail I wanted to ask folks here. Dgd had cautioned us earlier about the "protection diode" that we are using - should it fail. Briefly, we have Aux2 output of one controller connected to our 3-ph load bank (home-made clipper) via SS relay. This signal is 12V. We also have an Omron voltage sensitive relay connected to this relay, but it is a 24V output. The diode, Dgd pointed out is the only thing separating the two, different outputs. I just wondered if any one might suggest a better protection scheme? I've seen some small, low-power switch-mode DC/DC converters...there are DIN rail power supplies (a bit pricier)...or maybe just a linear voltage regulator? I'd like to keep it simple.
thanks for any suggestions, ~ks
