Sentek Dynamics’ PA Series replacement power amplifiers are available for most other vibration test equipment manufacturers obsolete, inefficient power amplifiers. The PA Series amplifiers are nearly twice as efficient as older air and water-cooled amplifiers and provide a significant savings in power consumption and electrical bills. So significant, in fact, that the savings can offset the cost of a replacement amplifier in a very short period.
Designed with the latest, field-proven MOSFET technology, the 12 kVA power-modules consist of two independent 6 kVA sub-modules to ensure continued operation in the event of a sub-module failure. Design features include: Heatsinks and fans to allow safe, continuous operation at high output for extended periods of time: interchangeable, modular sub-modules for easy replacement if required; and built-in operation and fault LED lights to provide a quick source to identify failed components
