Daikin KF – Minor Loop Control Method Drive (for AC current)

Market leaders in environmentally responsible heat pumps, ventilation and air conditioning systems for domestic, commercial and industrial applications.

  • The Daikin KF Minor Loop Control Method Driver controls the LEM valve which detects the spool position by a differential transformer to carry out a feed back control (minor feed back).
  • Owing to the constant-current characteristics, the variations of the supply voltage and output current by a solenoid can cause a temperature rise but this rarely happens.
  • The output radio wave corrugation (dither frequency, amplitude) is et up so that the hysteresis of a solenoid proportional control valve and a resolution power can get the best values.
  • Since the current is controlled by PWM (pulse width modulation) method, heat generation from the drive is reduced to a small amount.
