Voltage amplitude controlled reversing D.C. power circuit

摘要: The circuit permits control of two D.C. motors in both speed and direction over a single pair conductor line. Control circuits produce voltage regulated amplitude. controlled are responsive to pulses opposite polarity. A zener diode passes voltages above predetermined level activates switches that cause the motor run first direction. Voltages do not peak at sufficient initiate breakdown utilized activate second set capacitor time delay for amplitude diode. Once is activated latched off.
