The Labworks dPA-153 Class D switch mode Power Amplifier utilizes patented high-efficiency output circuitry to provide the high voltage random vibration peaks required to drive the shakers to their rated maximum output at a fraction of the input power required by conventional linear amplifiers. The user-friendly front panel digital display indicates the operational status of the amplifier's output as well as a complete set of vibration shaker system diagnostics. The amplifier monitors all vital shaker system parameters to protect against vibration system damage and reports the cause for any amplifier limiting or protective shutdowns via its digital display . The dPA-153 Amplifier family features internal protection from both over current and over temperature conditions insuring long term amplifier reliability. Full external interlock capability is provided to guard against payload damage as may be required by a vibration test program or critical specimen parameter. Four models of the dPA-153 are available, matched to Labworks most popular shaker systems: Labworks Shaker Amplifier Model ET-140 dPA-153-0 FG-143 dPA-153-3 ET-127 dPA-153-7 ET-139 dPA-153-9 |
