28VDC Power Supply                 2-21
     Two power supplies feed the same DC line but are diode isolated. The diodes keep the power supplies from "talking to each other" and prevent damaged to pass transistors, over current sensors etc.


     Some of my favorite power supplies use constant voltage transformers. Most of mine are made by Sola. These type of power supplies are all most bullet proof and are perfect for dynamotors. They do not generate any RFI.
