GDA-20P is motor actuated proportional damper actuator controlled by the signal DC 0~10V or 4 ~ 20mA, and designed for damper control in HVAC system and can provide 0 ~10V position feed back signal.

Used for operating Damper for ventilation and Air handling facilities.
Nominal torque is 20Nm and can be covered damper surface area for 4㎡.
Proportional operation will be activated by DC 0 ~10V or 4 ~ 20mA and possible to be DC 0 ~ 10V position feedback signal output.

Damper rotation can be selectable direction ( CW or CCW ) by jumper PIN.
Damper moves by control signal that it maintains same position unless changing control signal.
When operating power is at normal and at no control signal, Actuator moves to the direction of " 0°" or " 90°" ( operating direction can be changd by jumper PIN ).
When power is OFF, Actuator will be stopped at current position.
