Se trata de un dispositivo eléctrico compuesto por un acumulador de energía, asociado a un tablero de comando que contiene contactores, circuitoseléctricos y convertidores, y a un convertidor de corriente, mediante los cuales es posibleaccionar un motor eléctrico acoplable al motor del ascensory curso de freno del mismo. De esta manera se conduce el ascensor de manera independiente del comando propio.It is an electrical device made up of an energy accumulator, associated to a command board containing contactors, electrical circuits and converters, and to a current converter, by means of which it is possible to drive an electric motor that can be coupled to the elevator motor and the brake course of the same. In this way the elevator is driven independently of the command itself.
