SPUTNIK AR230-2-S Electric Actuator

SPUTNIK AR230-2-S is an electromechanical actuator without a return spring from the AR series, designed for controlling air dampers in general supply and exhaust ventilation and air conditioning systems. The device provides reliable opening and closing of dampers with a torque of 2 Nm and operates from a 230 V AC (50/60 Hz) power supply.

The actuator features 2/3-point control: applying voltage to the corresponding contacts causes the shaft to rotate in the "open" or "close" direction. When voltage is removed, the shaft maintains its position, allowing the damper to be fixed in intermediate positions. The AR230-2-S model is equipped with auxiliary microswitches (limit switches) for monitoring the damper's end positions.

The device is housed in a durable plastic enclosure with an IP54 protection rating, ensuring resistance to dust and water splashes. The actuator is designed for mounting directly onto the damper shaft using a universal mounting clamp and can be installed on round shafts with a diameter of 6–16 mm or square shafts of 5–12 mm.

Key Features and Benefits

• 2/3-Point Control Without Return Spring: The actuator has no return spring, allowing the damper to be fixed in any intermediate position when voltage is removed. Control is achieved by applying 230 V voltage to the corresponding contacts (e.g., N+L1 — open, N+L2 — close).

• Built-In Limit Microswitches: The AR230-2-S model is equipped with one built-in microswitch for monitoring the damper's end positions (open/close). The monitored angle position (5° or 85°) is selected by turning a switch on the actuator's top cover. This allows the actuator to be connected to controllers and monitor the damper status from a dispatch point or using indicator lamps.

• Manual Override and Mechanical Indication: If necessary, the actuator can be switched to manual mode by disengaging the gearbox using a lever on the housing. A mechanical position indicator on the housing allows visual monitoring of the damper rotation angle.

• Simple and Reliable Installation: The actuator is mounted directly onto the damper shaft using a universal mounting clamp. It supports round shafts of 6–16 mm diameter and square shafts of 5–12 mm. The actuator is attached to the valve body using a universal mounting plate or directly to the housing.

• High Reliability and Long Service Life: The actuator is rated for 60,000 open/close cycles, requires no maintenance, and remains operational over a wide temperature range from -30 to +50 °C. The IP54-rated housing provides protection against dust and moisture during operation in ventilation systems.

• Low Power Consumption: Power consumption during movement is only 2.5 W, and in holding mode — 0.7 W. The calculated power is 5 VA.

• Compatibility with Other Manufacturers' Equipment: The SPUTNIK AR230-2-S actuator is a complete analogue of such models as Belimo CM230-L/R, Dastech DA-02N220A, Nanotek LM 230 B, Lufberg DA02N220S, and others.

Technical Specifications

Below are the detailed technical parameters of the SPUTNIK AR230-2-S electric actuator.

Installation and Connection

Installation

The AR230-2-S electric actuator is mounted directly onto the air damper shaft:

• Shaft Attachment: The universal mounting clamp secures a round damper shaft of 6–16 mm diameter or a square shaft of 5–12 mm.

• Attachment to Valve Body: A universal mounting plate or direct attachment to the valve body ensures reliable fixation.

Rotation Direction

Changing the shaft rotation direction is done using the "CW-CCW" switch on the actuator housing.

Wiring Diagram

Control is 2/3-point (reversible): applying voltage to the corresponding contacts causes the shaft to rotate in the desired direction.

• N + L1: open

• N + L2: close

Manual Override

If necessary, the actuator can be switched to manual mode:

• Disengage the gearbox using the lever on the housing

• Rotate the actuator shaft manually

Limit Switch Adjustment

The AR230-2-S model is equipped with a built-in microswitch for monitoring end positions. The monitored angle position (5° or 85°) is selected by turning the switch on the actuator's top cover.

Applications

The SPUTNIK AR230-2-S electric actuator is designed for automating air dampers in the following systems:

• General Supply and Exhaust Ventilation: Opening and closing supply and exhaust dampers upon command from the control system.

• Air Conditioning Systems (HVAC): Controlling mixing chamber and recirculation air duct dampers.

• Air Valves: Installation on valves with a damper area of up to 0.4 m².

• Smoke Extraction and Fire Protection Systems: Controlling dampers with end position monitoring.

• Building Automation (BMS): Integration into dispatch systems with the ability to monitor damper status via limit switches.

Why Choose the SPUTNIK AR230-2-S?

The SPUTNIK AR230-2-S electric actuator is a reliable and easy-to-operate solution for automating air dampers in ventilation and air conditioning systems.

1. Reliability and Longevity: A service life of 60,000 cycles, no maintenance requirements, and an IP54 protection rating guarantee long-term trouble-free operation in ventilation systems.

2. Application Versatility: 2/3-point control allows the actuator to be used both for simple open/close operations and for fixing the damper in intermediate positions.

3. Status Monitoring Capability: Built-in limit switches provide a signal about the damper's end positions to the controller or operator panel, enhancing system information content.

4. Easy Installation and Setup: The universal clamp fits various shaft sizes, while the rotation direction switch and limit switch adjustment simplify commissioning.

5. Energy Efficiency: Low power consumption (2.5 W during movement, 0.7 W in holding mode) allows the actuator to be used in systems with limited energy resources.

Important Note: The SPUTNIK AR230-2-S electric actuator does not have a return spring. When voltage is removed, the damper remains in its current position. For systems requiring automatic closing upon power failure, models with a return spring (ARF series or equivalents) should be selected. The product is active in the manufacturer's line. Installation and connection must be performed by qualified personnel following safety regulations. Always verify compatibility with the nameplate and official documentation for the specific device.
