Fig. 2.2. Spice simulation of power supply showing the positive and negative rails from a 120VAC input.

We did not have a chance to build the power supply because we had to have a special transformer to achieve the required voltage rails. This was not in our budget so we had to find an alternative way to build the voltage rails.

We reverted to using 4 AC to Dc converters rated for 25VDC & 1.5Amps each.

We did not have any problems with packaging since we have reduced the number of components needed drastically.
