Abstract
A system for providing one or more voltages at predetermined magnitudes. The system may be supplied with power having a range of voltage magnitudes without affecting the predetermined magnitudes of the one or more voltages provided by the system and without a need to change circuitry of the system. The system may be connected, for example, from 28 VDC to 250 VAC without affecting the predetermined magnitudes of the output voltage or voltages. This system is protected from a mistaken power hook-up thought to be for 28 VDC but actually being connected to 250 VAC, which could be a disaster for a system not having the present circuitry. The system may be used for supplying power for opto-couplers in relay detection and other applications. The system may incorporate lightning and reverse polarity protection, reference and regulated voltages, an output driver, and input isolation circuitry.
