ATOS Amplifier Board E-ME-AC-05F Introduction
1. Product Overview:
• The E-ME-AC-05F is an electronic amplifier produced by ATOS (Italy), primarily used for driving proportional flow control valves, proportional pressure valves, and other proportional valves, as well as single proportional pumps.
• It amplifies the voltage or power of the input signal to control the electromagnets of proportional valves or proportional pumps, achieving precise regulation of hydraulic systems.
2. Technical Features:
• PWM Modulation: Utilizes Pulse Width Modulation technology for precise current control.
• Current Negative Feedback Constant Current Control: Ensures stable and accurate output current.
• Independently Adjustable Ramp Times: The rise and fall times can be independently adjusted to meet different control requirements.
• High Precision, Ultra-Compact, Environmentally Friendly: Features a compact design, stable performance, and meets environmental standards.
• Long Service Life, Low Heat Generation, Low Power Consumption, Strong Adaptability: Suitable for various harsh industrial environments.
3. Electrical Parameters:
• Power: 0.35 kW (may vary by model).
• Current Adjustment Range: 0-3 A (specific range may vary by model).
• Load Impedance: 2-45 Ω (specific impedance may vary by model).
• Control Value Input: Differential input ±10 V, four control value inputs, start-up voltage ±10 V; current input 4 to 20 mA.
• Power Supply Voltage: Typically 24 V DC (specific voltage may vary by model and application).
4. Functions and Applications:
• Functions: The E-ME-AC-05F amplifier converts the reference signal input from the machine's central control unit into a current signal proportional to the proportional electromagnet of the valve, enabling precise regulation of hydraulic systems.
• Applications: Widely used in hydraulic systems, mechanical equipment, heavy-duty machinery, hydraulic transmission systems, and other fields for driving proportional valves and proportional pumps to achieve precise control of parameters such as pressure and flow rate.
5. Structure and Design:
• Modular Design: Facilitates integration into valve types, enhancing system flexibility and maintainability.
• Printed Circuit Board Structure: Mounted on a printed circuit board in a European format measuring 100*160 mm, suitable for installation in racks.
• Protection Rating: Some models feature an IP67 protection rating, suitable for outdoor operations and harsh environments.
6. Supporting Equipment and Options:
• Supporting Rack Mounts: Such as 19-inch rack types VT19101 and VT19102, as well as fully enclosed rack mount VT12302.
• Supporting Power Supply Units: Such as the compact power supply unit VT-NE30-2X.
• Options: Include amplifier boards with dual position sensors, different ramp time ranges, gating inputs, ramp on/off inputs, etc.
