摘要
Control device delivers at its output pulse width modulated voltage signal and a signal during a certain time interval of the charge-discharge cycle of connected storage heaters. A display unit is controlled in accordance with a charge-discharge state of a capacitor, whose charge-discharge is controlled by a two-stage amplifier to which one stage the time dependent signal is applied, and and second stage is so operated by the pulses, that pulses of one polarity provide the supply voltage, and those of the other polarity the voltage at a control electrode.
