    • A system for controlling the connection of power from a mains supply (11) to electrical devices (22) by way of switching devices (19). The system includes a low voltage, direct current power supply (10), a plurality of command units (15) connected to and powered from the power supply by way of an electrical connection (14), and a plurality of switching devices (19) connected to and powered from the power supply by way of the electrical connection (14). Respective ones (15A, 15B and 15C) of the command units are arranged to generate uniquely coded pulse-form command signals and to feed the command signals to a central processing unit (18) by way of the electrical connection (14), and the central processing unit is arranged to generate pulse-form actuating signals having codes determined by respective ones of the command signals. The central processing unit is arranged to feed the actuating signals to the switching devices (19) by way of the electrical connection (14). The power supply (10) incorporates a voltage regulator (11) which includes circuitry which functions to detect the presence of the pulse-form signals on the electrical connection (14), and the voltage regulator includes means for modulating the output voltage of the power supply between two discrete levels responsive to and at a rate corresponding with that of the pulse-form signals.
    • 一种用于通过开关装置(19)来控制从主电源(11)到电气装置(22)的电力连接的系统。 该系统包括低压直流电源(10),通过电连接(14)连接到电源并由电源供电的多个指令单元(15)和多个开关装置(19) 通过电连接(14)连接到电源并由电源供电。 命令单元的各个(15A,15B和15C)被布置成产生唯一编码的脉冲形式命令信号,并且通过电连接(14)将命令信号馈送到中央处理单元(18),并且 中央处理单元被布置成产生具有由相应的命令信号确定的代码的脉冲形式的致动信号。 中央处理单元被布置成通过电连接(14)将致动信号馈送到开关装置(19)。 电源(10)包括电压调节器(11),其包括用于检测电连接(14)上的脉冲形式信号的存在的电路,并且电压调节器包括用于调制功率的输出电压的装置 在两个离散电平之间提供响应于和与脉冲形式信号相对应的速率。
