SignalForce Amplifiers

SignalForce amplifiers, or shaker amplifiers, provide very high levels of efficiency with superior levels of performance. These amplifiers occupy little space and are suitable for driving shakers from all manufacturers, as well as other laboratory applications. While new shaker systems include matched amplifiers, Data Physics engineers can match our modern power amplifiers to any electrodynamic shaker.

EMC has been a major factor in the design of the digital switching amplifiers. Full use has been made of Faraday cages, compartmentalization, filtered interconnections, segmented wiring, common mode chokes for symmetrical currents, mains filters, optical coupling of signals and screened cables. All amplifiers are also available CE marked.

Linear amplifiers are available from 30 to 1000 VA and digital switching amplifiers are available from 1 kVA to 470 kVA. Switching amplifiers are used for medium and large shakers and are commonly replaced on very old shakers.

• Up to 95% efficient
• Switches at >105 kHz
• 1 KVA, 5 KVA, and 10 KVA modules
• Includes field and degaussing supplies
• Safety interlocks
• Protection against over current and over temperature
• Remote and chamber interfaces

More Control with E-Link

Multi-bay digital switching amplifiers represent a sizeable investment and can provide a significant amount of power, generally more than 120 kVA. With large systems and amplifiers it becomes more important to monitor and control the amplifier remotely and instantly. The E-Link remote control interface does just that by providing the user easy access via an Ethernet connection to the amplifier allowing remote control of all amplifier functions and providing a remote dashboard of all amplifier parameters. This means you can optimize the amplifier setup for each test right from your control desk.

E-Link allows the user to remotely shutdown extra power bays or reduce the field current when running low force tests. The result is not only less wasted energy and lower energy costs, but increased life of the system for reduced maintenance costs.

E-Link Features:

• TCP/IP Connectivity – not cable length prohibited, such as RS-232 or USB devices
• Complete Amplifier Control and Status Monitoring
• Digital Gain Control
• Digital Armature Voltage and Current readouts with visual indications showing high and low limits
• Digital Field Supply Voltage and Current readouts with visual indications showing high and low limits
• Armature and Field Coil water temperature monitoring
• Armature Temperature Monitoring
• Persistent Emergency Stop and Gain Control on every tab
• Fully integrated Fault Monitoring
• Switching for Sine/ Random Selection
• Switching for Field Current- 50% and 100% field
• Output Waveform Display for Diagnostics
