Non-Spring Damper Actuators with torque 4 Nm - RA4 series

damper actuators 4Nm - RA4-series

Description

VCP non-spring return damper actuators are suitable for many applications including motorised control of dampers in ventilation systems such Building Automation Systems (BAS), Building Management Systems (BMS) or Heating, Ventilation, and Air Conditioning (HVAC) environments.

Solutions for VCP non-spring return damper actuators are ideal for control dampers, air handlers, economizer units, VAV terminal units, fan coil units, fan shutters, and unit ventilators.

VCP non-spring return damper actuators to be direct mount on standard damper shafts to control dampers.

The RA4-series non-spring return damper actuators with torque 4 Nm are used to regulate dampers up to approx. 1.0 m2.

The 4 Nm non-spring return damper actuators RA4 24D and RA4 220D are with control signal on/off (two-position) or 3-point (3-point flaoting / tri-state).

The 4 Nm non-spring return damper actuators RA4 24V is with control signal 0-10 Vdc and RA4 24C is with control signal 4-20 mA .

Auxiliary switch equipped on the digital (on/off or 3-point) types of non-spring return damper actuators types RA4 24D S1 / RA4 220D S1 and on the analogue (0-10 Vdc or 4-20 mA) types of non-spring return damper actuators types RA4 24V S2 and RA4 24C S2.

Feedback signal is standard on all the 4 Nm non-spring return damper actuators RA4-series with analogue control signal.

The 4 Nm non-spring return damper actuators RA4-series are equipped with position indicator, manual override by push button, direction of rotation changeable via switch on pcb.

Running time for all 4 Nm non-spring return damper actuators RA4-series is 35 seconds.
