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.
Switching Amplifier Features:
Designed with the Data Physics LE-series water cooled shakers in mind, the new LE-DSA15 IGBT amplifiers are based on the same reliable and robust architecture as the LE-DSA10 series units which have a proven track record of continuous high output operation. The LE-DSA15 amplifiers are rated for 200 Vrms continuous operation which will allow for high velocity testing without the need for an output transformer. When connected to a LE-DSA15K amplifier, the LE-2016-3″ shaker systems are capable of up to 170 in/sec (4.32 m/s) velocity shock at 11 mSec.
Less is More
The elimination of the output transformer allows the shaker to be direct-coupled, making it possible to operate the shaker at less than 5 Hz.
The transformerless design also eliminates the need for switching for sine, random, and shock profiles.
The overall size of the amplifier is thus reduced, freeing up valuable floor space in your vibration test laboratory.

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.
