Schneider MD10SR - 24M Actuator Product Description​ Model​ MD10SR - 24M​ Product Range and Type​ The Schneider MD10SR - 24M is a high - quality electric actuator, part of the reliable MD10SR product series. Engineered with precision, it's designed to offer efficient and dependable performance for a variety of industrial and commercial applications.​ Actuator Application​ Specifically crafted for use with dampers, this actuator plays a crucial role in regulating air flow within ventilation and HVAC systems. Its rotary motion ensures smooth and accurate adjustment of the damper position, optimizing system performance and energy efficiency.​ Control and Electrical Features​ Control Type: Features an automatic reset mechanism, ensuring seamless operation in various conditions. This means the actuator can return to a pre - set position under specific circumstances, enhancing system reliability.​ Rated Supply Voltage: Operates on a 24 V AC/DC power supply, providing versatility and compatibility with different electrical systems. Whether in an AC - powered industrial setting or a DC - based control system, this actuator can function effectively.​ Analogue Input Range: Accepts an input signal in the range of 2...10 V DC, enabling proportional control. This allows for fine - tuned adjustment of the actuator's operation based on the input, ensuring precise control over the damper's position.​ Feedback Signal: Provides a feedback signal of 2...10 V DC, allowing for accurate monitoring of the actuator's position. This feedback loop is essential for maintaining optimal system performance, as it enables the control system to make real - time adjustments.​ Transformer Rated Power: Has a transformer rated power of 5.5 VA, ensuring a stable and reliable power supply. This power rating is optimized to meet the actuator's operational needs while minimizing energy consumption.​ Power Consumption: During operation, it consumes 3.5 W of power, with an AC power consumption of 5.5 VA. The hold - in power consumption is 2.5 W, making it energy - efficient when in a static position. This low power consumption not only reduces operating costs but also contributes to a more sustainable operation.​ Power Loss Return: Incorporates a spring return mechanism, which ensures the actuator returns to a safe position in case of power loss. This is a critical safety feature, especially in applications where maintaining a specific damper position is vital for system integrity.​ Control Signal: Operates on a proportional/modulating control signal, providing flexibility in different control scenarios. This type of control signal allows for smooth and continuous adjustment of the actuator's position, enabling precise control over the air flow through the dampers.​ Electrical Insulation Class: With an electrical insulation class of Class III, it offers enhanced safety in electrical installations. This class of insulation provides additional protection against electrical malfunctions, ensuring user safety and reliable operation.​ Physical Specifications​ Tightening Torque: Generates a tightening torque of 10 lb.in (1.1 N.m), providing sufficient power to operate the dampers effectively. This torque output ensures that the actuator can overcome any resistance and move the dampers smoothly, even in challenging operating conditions.​ Position Indicator: Features a stroke indicator on the bracket, allowing for easy visual monitoring of the actuator's position. This visual feedback simplifies the process of checking the damper's status, whether during installation, maintenance, or regular operation.​ Lead Length: Comes with a 1 - m lead length, providing enough cable for convenient installation and connection to control systems. The sufficient lead length allows for flexibility in mounting the actuator and connecting it to the necessary control components.​ Spring Return Timing: The spring return timing is set at 75 s, ensuring a controlled and timely return to the default position in case of power loss. This specific timing is optimized to balance the need for a quick response with the mechanical limitations of the spring mechanism.​ Actuator Rotation: Can rotate up to 95 °, with a maximum rotational range adjustment of 95° (limited by an adjustable end stop). This precise rotational control allows for accurate adjustment of the damper's opening and closing angle, optimizing air flow control. The adjustable end stop provides flexibility in setting the maximum rotation range according to the specific application requirements.​ Environmental Specifications​ IP Degree of Protection: Has an IP43 enclosure class, protecting against solid objects larger than 1 mm and water splashing from any direction. This makes it suitable for use in a variety of indoor and outdoor environments, even in areas with some exposure to moisture and dust. The IP43 rating ensures that the actuator can withstand harsh environmental conditions without compromising its performance.​ Ambient Air Temperature for Operation: Can operate in an ambient air temperature range of - 30…50 °C, ensuring reliable performance in different climatic conditions. Whether in cold industrial settings or warm, humid environments, the actuator can function without compromise. This wide temperature operating range makes it suitable for use in various regions.​ Relative Humidity: Can withstand a relative humidity of 0…95 % RH, non - condensing. This high humidity tolerance makes it suitable for use in areas with high moisture levels, such as near water treatment plants or in tropical climates. The non - condensing requirement ensures that the actuator's electrical components are not affected by moisture buildup, maintaining its reliability over time.​ Ambient Air Temperature for Storage: Can be stored in an ambient air temperature range of - 40…80 °C, ensuring the longevity of the product when not in use. This wide storage temperature range allows for convenient storage in different environments, from cold storage facilities to hot warehouses.​
