    • A simplified and economical power supply for redundant computer systems of control systems is disclosed. These control systems may include burner control for furnaces. The safety and reliability of the system are increased. The power supply comprises one single common voltage supply in the form of a self-monitoring power pack unit SN having a power pack NT, an undervoltage monitor UW and an overvoltage monitor. The self-monitoring power pack unit communicates with the redundant computer units P1, P2 via a supply line 1e. This single self-monitoring power pack unit is used according to the invention instead of the known fully parallel two-channel operation with two computer units and two power packs with appertaining components and supply lines. The overvoltage monitor UW and the undervoltage monitor UW are preferably checked for operability through the periodic transmission of a test signal.
    • 公开了用于控制系统的冗余计算机系统的简化和经济的电源。 这些控制系统可以包括用于炉的燃烧器控制。 系统的安全可靠性得到提高。 电源包括一个具有电源组NT,欠压监视器和过电压监视器的自监控电源组件SN形式的单个公共电压源。 自监控电源组单元经由电源线1e与冗余计算机单元P1,P2通信。 根据本发明使用该单个自监控电源组件单元,而不是已知的完全并行的双通道操作,具有两个计算机单元和两个具有组件和电源线的电源组。 优选通过测试信号的周期性传输来检查过电压监视器ÜW和欠压监视器UW的可操作性。
