مشغل التحكم في الجهد
Precision Analog Servo Motor for Continuous HVAC Valve and Damper Regulation
Product Overview
The مشغل التحكم في الجهد is an advanced, analog-driven servo motor designed specifically for use in the HVAC systems of buses, vans, mini-buses, and commercial vehicles, where precise, continuous control over airflow and temperature regulation is essential. Unlike traditional on/off or multi-position actuators, this unit enables proportional, infinitely variable control of dampers and valves through a 0V to 10V DC analog signal input, making it ideal for applications requiring smooth transitions and fine-tuned climate management.
This actuator integrates seamlessly into modern vehicle climate control architectures that utilize electronic control units (ECUs), sensors, and automated feedback loops. By responding directly to voltage signals from the HVAC controller, it allows for dynamic adjustment of air distribution, heating flow, or recirculation levels—delivering enhanced comfort, energy efficiency, and system responsiveness across diverse operating conditions.
With its robust construction, wide operating range, and compatibility with both 12V and 24V systems, the Voltage Control Actuator is a preferred solution for OEM manufacturers, fleet operators, and HVAC system integrators seeking high-performance, scalable climate control technology.
Key Features & Technical Advantages
- Continuous Analog Control (0–10V):
The actuator accepts a 0V to 10V DC control signal, enabling infinite position adjustments across the full rotation range. This allows for smooth, linear modulation of damper or valve openings, providing optimal airflow and thermal balance without abrupt changes. - High-Precision Positioning:
Equipped with a potentiometer-based feedback system, the actuator continuously monitors its rotational position and sends real-time data back to the HVAC ECU. This closed-loop control ensures accuracy, repeatability, and stability—even under fluctuating loads or environmental conditions. - Proportional Torque Output:
Delivers consistent torque of 4 kgf·cm during operation and up to 12 kgf·cm when locked, ensuring reliable performance even in high-resistance duct configurations typical in commercial vehicles. - Dual Voltage Compatibility:
Supports both DC 12V and DC 24V power supplies, making it suitable for a wide range of vehicle types including passenger vans, minibuses, school buses, and light commercial trucks. - Low Power Consumption:
Operates efficiently at just 3W with a maximum current draw of 108mA, minimizing electrical load and improving overall system efficiency. - Quiet Operation:
With a noise level of max. 43 dB(A), it operates silently—critical for maintaining passenger comfort in enclosed transport environments such as buses and coaches. - Wide Environmental Tolerance:
Designed to function reliably in extreme climates, with an operating temperature range of -30°C to +80°C and storage capability up to +85°C, ensuring durability in tropical, arctic, or desert conditions. - Extended Service Life:
Built for up to 200,000 operational cycles, offering long-term reliability and reduced maintenance needs in high-use commercial fleets. - Compact & Modular Design:
The actuator measures 83 × 50 × 28 mm, while the optional V-control box (60 × 35 × 27 mm) houses the internal electronics and signal processing circuitry. This modular setup allows for flexible installation and easy integration into existing HVAC assemblies. - Customizable Options:
- Rotational angle and position can be custom-designed to meet specific OEM requirements.
- Supports custom logo printing and branding for original equipment suppliers.
- Offers tailored wiring harnesses and mounting brackets upon request.
- Certified Quality Assurance:
Complies with ISO 9001 and TS16949 standards, ensuring strict quality control, traceability, and compliance with automotive industry norms.
How It Works: Analog Feedback & Proportional Control
The Voltage Control Actuator operates on a proportional control principle:
- When the HVAC controller outputs a 0V signal, the damper closes completely.
- As the voltage increases (e.g., 5V), the actuator rotates proportionally to open the damper partially.
- At 10V, the damper reaches full opening.
- Throughout this process, the built-in potentiometer provides continuous position feedback, allowing the ECU to adjust the signal dynamically based on actual conditions.
This analog control method eliminates the need for discrete steps or complex digital protocols, offering smoother airflow regulation compared to pulse-width modulation (PWM) or relay-based systems. It is particularly effective in large-volume vehicles where gradual temperature changes and uniform air distribution are critical.
