摘要
A control system utilizing a magnetic reed switch responsive to the output of a battery regulated power supply for controlling an impedance means to maintain the voltage output of the supply within a predetermined range. In the preferred embodiment, the power supply transformer has a separate secondary winding for controlling the energization of a relay coil to initially activate the reed switch. When the a.c. power is removed, particularly under adverse conditions, the battery maintains the output supply voltage within a predetermined voltage range until the relay coil senses a predetermined minimum voltage and in response thereto opens the reed switch effectively changing the impedance value of the impedance means from a finite value to an infinite value.
