Electrodynamic Shaker Power Amplifier
Product Details:
Sdyn's Power Amplifiers use compact and extremely efficient power modules. These help to amplify the small electrical signal from the Vibration Controller to a proportionally high voltage and high current output, that is ideal to drive the shaker. The design of the Power Amplifier ensures energy and space. DSA series Power Amplifier use solid-state power devices in a Class-D Full Bridge configuration. They are digitally modulated with a high frequency pulse width modulated signal with efficiency of over 92%. Their modular construction makes them easy to handle and arrange for maximum output power with direct coupling to any resistive or inductive load. Integral air cooled design ensures continuous duty cycle without sacrificing performance at peak temperature and humidity.
These Power Amplifiers are compatible with any make of Electrodynamic Shakers and are designed to provide continuous rated voltage and current at high ambient temperature and humidity. A low knee filter provides smooth output, while removing switching noise and electromagnetic interference. A zobel network is dedicated for impedance matching over a wide range of frequencies for inductive loads. Adjustable current limit is also provided for controlling maximum output power so that accidents can be avoided.
Assembled in industry standard modular racks, all modules of our Power Amplifier are rack mountable. Removing and installing modules is made easy via guide rails on which every module is designed to slide. Designed to meet international design and safety standards, every module of our Power Amplifier is feature rich and contains its own power entry, power filtering, error indication and EMI conforming systems. Continuous upgrade of technology to better meet the international standards and reduce the carbon footprint of our system is a never-ending process at Sdyn. Through our various training, services and maintenance programs, we keep our customers updated with the latest product offerings and upgrades.
