Sdyns Low Thrust Series of Electrodynamic Vibration Systems comprises of our air cooled shakers and air cooled amplifiers. These are designed for low payload capacity and for tests that require high resonance and frequency response.

A customer chooses this range for its low price, small form factor, and high reliability. These systems are generally very specific to the customers testing requirements and offer very little scope for future up-gradation.

Standard features of Low Thrust Series are:

• Electromagnetic Armature and Field Coils
• Magnesium Alloy Casting based Armature Structure
• Dual Field Coil based Magnetic Circuit
• Class D Full Bridge (H Bridge) Power Amplifier

Advanced features of Low Thrust Series are:

• Explosion Proof Design
• Remote Operation from PC
• Modified Shaker and Controller for Damper Testing using Force and Acceleration Sensing
• Modified Shaker and Controller for Rubber and Elastomer Testing using LVDT and Load Cell

Some common applications of Low Thrust Series are:

• Testing to meet BIS Test Specifications
• Electronics and Electrical Component Testing
• LED and Bulb Testing
• Sensor and Transducer Testing
• Transmission Line Damper Testing
• Rubber and Elastomer Testing

Ranges covered under Low Thrust Series are:

• SEV 125 (100 to 150 kgf)
• SEV 140 (200 to 300 kgf)
• SEV 180 (400 to 600 kgf)
• SEV 240 (1000 to 1500 kgf)

Sdyns Medium Thrust Series of Electrodynamic Vibration Systems comprises of our air cooled shakers and air cooled amplifiers. These are designed to address a wide range of test objects and attachments which represent generalised testing requirements.

A customer chooses this range for its value for money, high scalability and high reliability. Being the most commonly opted range, these systems are used where a variety of tests are conducted on a single system. With features like body isolation and trunnion being standard, this series is the first pick of every national and international testing laboratory.

Standard features of Medium Thrust Series are:

• Electromagnetic Armature and Field Coils
• Magnesium Alloy Casting based Armature Structure
• Dual Field Coil based Magnetic Circuit
• Class D Full Bridge (H Bridge) Power Amplifier

Advanced features of Medium Thrust Series are:

• Long stroke design with displacement up to 76 mm (3 inch)
• Explosion Proof Design
• Remote Operation from PC

Some common applications of Medium Thrust Series are:

• Automotive parts and assemblies
• Locomotive parts and assemblies
• Aeronautic parts and assemblies
• Industrial parts and assemblies

Ranges covered under Medium Thrust Series are:

• SEV 300 (2000 to 2500 kgf)
• SEV 360 (3000 to 3500 kgf)
• SEV 440 (4000 to 6000 kgf)

Sdyns High Thrust Series of Electrodynamic Vibration Systems comprises of our water cooled shakers and air cooled amplifiers. These are designed for large and heavy specimens of irregular shapes and sizes.

A customer chooses this range for its sheer power, very high payload capacity, and high reliability. Being a part of big projects, everything about these systems is as per the customers requirement.

Standard features of High Thrust Series are:

• Electromagnetic Armature and Field Coils
• Magnesium Alloy Casting based Armature Structure
• Dual Field Coil based Magnetic Circuit
• Class D Full Bridge (H Bridge) Power Amplifier

Advanced features of High Thrust Series are:

• Explosion Proof Design
• Remote Operation from PC

Some common applications of High Thrust Series are:

• Aeronautics and Astronautics
• Arms and Ammunitions

Ranges covered under High Thrust Series are:

• SEW 500 (7000 to 10000 kgf)
• SEW 590 (13000 to 16000 kgf)
• SEW 760 (29000 to 32000 kgf
