I am brand new to All About Circuits, and I must say, this is awesome. It has everything. I am looking to build a DC Resistive Load Bank. It would need to handle 28 VDC and a full load of 360 A in 4 steps of 90A, 180A, 270A, and 360A continuous. I have built a few simple Control Panels over the years,mainly fluid tempurature and pump controllers but this is new to me. I'm looking for the type of resistors,(ceramic, wire wound) configuration,(one, or more resistors per load step) cooling, (how to calculate enough air flow) etc. If anyone has had experience with the resistor setup it would be greatly appreciated.
