DSA series of solid state digitally modulated Power Amplifiers utilize pulse width modulation technique. The modular amplifier converts the mains input to a variable frequency adjustable power of delivery to inductive loads with extremely high (>92%) conversion efficiency to drive the Shaker. Amplifier modules are integral fan cooled and designed for continuous duty to drive corresponding shaker with the help of associated instrumentation.These amplifiers are compatible to drive electrodynamic shakers of any make worldwide and are designed to provide continuous duty RMS rated voltage and current to any type of load. Power modules of the switching amplifier are constructed using either HEFXET or IGBT assemblies for low conduction losses, high voltage & current capability to enhance the power density.New generation hi-rating Power Modules inducted into the latest series of DSA amplifiers have an inbuilt PWM management and generation. These modules are stacked in any master/any slave configuration for their parallel operation in the amplifier. Paralleled modules are synchronized through buffered clock and the 3-sigma design ensures peak current capability for continuous random operation.With further advancement in design, the feature of remotely operating the vibration system from a distance is introduced as remote link operated from a PC.+ Read More
