| 摘要 |
The present invention relates to a stand-by circuit (1) comprising a first input (100) for receiving a phase of the mains supply, a second input (101) for receiving a stand-by signal, a monostable switch (3), an AC-DC converter (4), wherein said switch (3) is adapted to connect said first input (100) electrically to said AC-DC converter (4) when said switch (3) is suitably energized, further comprising an energizer module (5) adapted to energize said switch (3) when at the output of said converter (4) there is a voltage other than the ground voltage, said energizer module (5) being further adapted to interrupt its energizing action upon said switch (3) if it receives a suitable stand-by signal at said second input (101). Said stand-by circuit (1) further comprises a switch (6) which allows, when closed, to energize said switch (3). |
