ABSTRACT:
A power supply which automatically adapts to different input power sources. A double pole, double throw, latching relay switches the primaries of the rectifier transformer to a series or to a parallel configuration depending upon the output voltage of the rectifier, thus adapting the circuit to either a nominal 220 VAC source or a nominal 120 VAC source. The control circuit also derives power from the rectifier transformer and is designed to operate even under the worst possible undervoltage or overvoltage conditions. The additional choice of 24 VDC power is available by the use of a diode OR circuit. When a 24 VDC source is connected to the DC input, it is also connected to the rectifier output through a diode, so that power is furnished to the load by whichever source has the higher voltage. In this configuration, a battery pack can be connected to the DC input to supply automatic backup power.
