  • Emergency power system for electromagnets
    Patent number: 4387305
    Abstract: A system is disclosed for providing emergency power to a load, such as an electromagnet (36), in the event of the failure of the main power source (20). The system utilizes two series connected battery banks (26, 28) which have a combined output voltage that exceeds the output voltage of the main power source (20), and which are maintained in a fully charged state by means of a battery charger (42). Upon the failure of the main power source (20), control circuitry (58) instantaneously transfers the battery banks (26, 28) to the magnet (36) preventing the dropping of the load. A timing relay is provided to periodically sense whether the main power source (20) has been restored, and to disconnect the battery banks (26, 28) from the magnet (36) after restoration has occurred.
