Thomson Electrak® HD Linear Actuator

Key Features and Benefits

The Electrak HD integrates advanced control systems, providing flexible operation and eliminating the need for separate control units. Its design offers higher performance, longer stroke lengths, and reduced power consumption compared to previous models, making it ideal for transitioning from hydraulic to electric systems.

Integrated "On-Board" Electronics

The Electrak Modular Control System (EMCS) forms the basis of the Electrak HD's integrated control, offering optional CANopen and SAE J1939 CAN-Bus support. This modular design simplifies installation, saves space, and reduces overall costs.

• Voltage options: 12, 24, 48 VDC
• Optional CANopen and SAE J1939 CAN-Bus for enhanced controllability
• Electronic shut-off point calibration for overload protection
• Continuous monitoring of critical parameters (end position, voltage, current, temperature)
• Dynamic brake for precise end-of-stroke positioning
• Optional low-current switching with automatic standby mode
• Optional end-of-stroke output signal
• Optional synchronization function for up to eight actuators

Superior Performance

With increased force capabilities and longer stroke lengths, the Electrak HD can handle applications previously beyond the reach of other electric linear actuators.

• Higher load ratings up to 16 kN, ideal for hydraulic-to-electric conversions
• Stroke lengths up to 1 meter (10 kN models) or 500 mm (16 kN models)
• Optimized design, including high-quality ball screw, reduces power consumption by up to 20%

Highest Protection Against Environmental Influences

The Electrak HD is tested against the strictest OEM criteria for mechanical and electronic components, ensuring reliability in harsh conditions.

• IP69K (static), IP67 (static), and IP66 (dynamic) ratings
• Operating temperatures from -40 °C to +85 °C
• 500-hour salt spray resistance
• CE, RoHS, and REACH compliant
• IP-X6 rating for dynamic protection against water jets

Additional Standard Features

• Integrated manual override
• Anti-rotation piston rod
• Integrated thermal overload protection
• Safety nut for ball screw failure
• Flexible clevis options (front and rear)

Bus Communication: The Future of Actuator Control

Controlling actuators via a network bus opens up new possibilities in machine design. Integrated control, monitoring, and feedback options eliminate the need for separate control units, simplifying machine construction, diagnostics, and installation while reducing hardware costs.

CAN Bus in Practice

The Electrak HD utilizes CANopen and SAE J1939 CAN bus standards, widely used in material handling, construction, and agriculture. Up to eight Electrak HD actuators can be connected to the same control unit and network.

• Enables complex real-time interactions between multiple actuators and systems.
• Benefits include enhanced control functions, real-time feedback for safety, shorter planning and installation times, increased flexibility, and reduced costs.

Control Architectures (with and without CAN Bus)

System without CAN Bus: Power is distributed to individual devices, and a central control system communicates separately with each actuator's control unit, requiring individual planning and configuration.

System with CAN Bus: Allows direct communication between control and actuators, simplifying the integration of multiple actuators. This architecture leads to simplified system planning, improved performance, better controllability, reduced installation times, and lower overall costs.

Synchronization Option

The synchronization option allows for precise, position-based movement of up to eight Electrak HD actuators. This feature is crucial for handling asymmetrical loads, lifting heavier loads, and achieving synchronized movement to multiple end positions, effectively replacing mechanical couplings.

• Benefits: Smooth operation, stable and potentially faster strokes, ability to handle asymmetrical loads, simplified installation with minimal wiring.
• Applications: Handling asymmetrical and heavy loads, lifting higher loads, integrated movement to multiple end positions, eliminating mechanical coupling.

Applications

The Electrak HD is suitable for a wide range of applications, including:

• Door/flap/hatch openers
• Assembly stations
• Solar collectors
• Driverless transport systems (AGV)
• Trucks, construction, and utility vehicles
• Road construction equipment
• Rail vehicles
• Logistics systems
• Emergency and rescue vehicles
• Switchgear
