Data Physics SignalForce Amplifiers combine high levels of efficiency with superior performance, while occupying little space and are suitable for driving shakers from all manufacturers.
Data Physics provides robust, reliable and efficient amplifier products that supply the power used to drive your test system to its limits. When selecting an appropriate amplifier, you need to consider the mass of your shaker’s armature, head expander, device under test and your test performance specifications, as these variables dictate overall power requirements. Data Physics offers a range of standard amplifier products specifically designed to meet comprehensive power delivery requirements while simultaneously assuring long-term, reliable operation.
Managing and minimizing the effects of EMC has been a major factor in the design of our 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 available CE compliant.

Power Amplifiers
Along with our SignalForce Power Amplifiers and Shakers, SignalStar® Vibration Controllers and SignalCalc® Dynamic signal analyzers, Data Physics provides fully integrated test and measurement solutions, all delivered from a single source. Our Engineers can match our modern power amplifiers to any electrodynamic shaker.
▍ Selection of Appropriate Power Amplifiers When considering what power amplifier is applicable for your testing needs, it’s important to remember Newton’s 2nd Law of Motion…the simple equation, F=ma, or Force = Mass x Acceleration. Acceleration: is given by the profiles to be tested, typically units of g for Sine and Shock, and g rms for Random. Mass: is the total moving mass including the shaker’s armature. The DUT, fixture, head expander (if applicable) or slip table + drive bar + bearings, and the shaker’s armature all add into the mass. Force: is the required force of the shaker for the given acceleration and mass. Vibration systems have different force ratings for Random, Sine, and Shock. If we think of force as directly proportional to an amplifier’s current output rating, then in general terms, the bigger and heavier the test item, the more power you’ll need to conduct your testing. Additionally, the higher the required test acceleration (g or g rms), the more power you’ll need. In sizing the proper replacement amplifier, it is important to know the system’s operational characteristics to match the best suited solution. Just as force is directly proportional to current, the shaker’s velocity is directly proportional to voltage. The maximum power of the shaker system is usually found right at the velocity to acceleration cross-over point. Data Physics offers a variety of power amplifiers to address a broad range of testing requirements. Our Linear Amplifiers provide compact and efficient solutions for smaller test items with comparably lower-intensity test inputs. These amplifiers also provide solutions for inertial and modal shaker applications. Our Digital Switching Amplifiers can be provided in a broad array of configurations, tailored to deliver the power necessary for more challenging testing requirements. |

▍ E-Link Shaker Systems Control for DSA10 Amplifiers
Reduce energy consumption and operating costs while extending the life of your shaker system.
With the SignalForce E-Link option, you can remotely control and monitor the performance of SignalForce shakers powered by DSA10 series amplifiers. Designed for easy access via Ethernet, SignalForce E-Link allows control of all amplifier functions and provides a remote dashboard of all amplifier parameters. This means that you can optimize the amplifier setup for each test right from your control desk. The easy-to-use interface allows you to shutdown extra power bays or reduce field current when running low force tests. Never waste energy again, reduce maintenance costs and extend the life of your system.
▍ Product 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 ● Embedded accelerometer monitoring The optional E-Link package can be purchased with new, or added to existing Data Physics DSA10 or Ling amplifiers. |

| ▍ Switching Units for Maximizing Available Power Vibration test labs that utilize multiple shakers often don’t require those test systems to be running simultaneously. To save on cost, a common amplifier, or set of amplifiers can be used to power select, individual shakers that are deemed appropriate for given test requirements. In addition to saving on an initial test equipment investment, switching units allow users to save on floor space and maintenance activities. Switchers have been made for both air cooled and water cooled systems in a variety of configurations and sizes. Switching units can be built into amplifiers for switching power between two shakers or can be custom designed for more elaborate user setups that include cooling. For larger setups, a specifically designed touch pad user interface is used to control the various switching combinations. |
