Transformers for multiple units could be centrally located and the low voltage AC then routed to each throttle. All transformers should be mounted in a fully enclosed metal cabinet and properly grounded. As this section of the throttles uses 120 volt AC power great caution should be taken in this area. Shown is the primary and secondary circuits and the components needed to power the throttles. The first schematic is of the Direct Current power supply for the throttles. The circuits although functional are meant to be used as guides for other designs. The diagrams and texts start with the transformer and rectifier circuits and some throttle designs and on to the addition of other features such as unplugable walk around control. The Waveform diagrams shown on this page are not technically correct but are meant to illustrate of the throttle output wave forms for a given control setting. The basic transistor throttle serves as a base to which other circuits are added. The throttles range from 'tried and true' to experimental designs. This page has a number of variations on transistor type throttles and related circuits.
