electric servo amplifier DFC-1100

  Product Description   DFC series single-phase servo amplifier is an accessory of combined instrument in DDZ type electric unit, which receives the signals from transmitting and regulating and manual control signal from other units, automatically regulates the operating mechanism and completes the regulating task by cooperating with the electric actuating mechanism. It is widely used in the regulating and control system of automation in the process of production in power plant, chemical industry, petroleum, metallurgy, mining and light industry when it works with other units of DDZ-type meters.
