Proportional Damper Actuator for duct ventilation system
HY-DF series damper actuators are to adjust the control air damper.The series are widely used in the building automatic control system of heating,ventilating,air-conditioning and cooling.HY-DF series air damper actuators provides the 4~32N.m torque.Every torque have two types to be chosen:
1.digital input 2.0(2)~10V and 0(4)~20mA proportional input
1.Install directly and needn't the linked apparatus,saving the time and cost of installation
2.The circuit possesses the function of electric overloading protection,and it doesn't need localized switch.There fore this reduces the consumption of power and improves the actuator's reliability.
3.Hand switch control,simplify the spot modulation of equipment,permit the hand localized on the emergent situation.
