Clock control for DC device in personal computer system providing switching of DC device at frequency of identified external clock signal

摘要

The clock control (1) has 2 current terminals provided with plug-in connections (3,4) for personal computer peripherals and a clock input with a 2-pin plug (2) having a 2.54 mm pin spacing, supplied with each AC voltage signal of given amplitude, with identification of an external clock signal for switching a DC device (5) at the same frequency as the clock signal.
