Daikin EPD & EPK - Open Loop Control Method Euro-Card

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

• The Daikin EPD & EPK Open Loop Control Method Euro Card Controls the KSP valve of an open look control system to optimum conditions.

• Owing to the constant-current characteristics, the variations of supply voltage and of current by a solenoid temperature rise rarely happens.

• The output radio wave corrugation (dither frequency, amplitude) is set up so that 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 driver is restrained to be the smallest.

• As the function (response time adjusting function) to vary the output current slowly for the variation of step like command input is provided, it enables the oil output to vary in shock-less. (for either build-up or pull-down process, each process can be independently adjusted).
