The connection for permanent power supply of electronic units in a network disconnecting from the source solves cases when the distribution network is intermittently disconnected from the power supply source because the main - high-power - devices are out of order during a given time interval. For such cases, a connection is designed, which uses change-over to switch from the supply power source (1) to the extra low-voltage power supply source (2), supplying without interruption electronic units (8) connected through a converter (6) accepting a wide range of input voltages. |
