Available with outputs ranging from 8 to 56 kVA, these switch-mode power amplifiers are designed to drive electrodynamic shakers with force ratings of at least 9.81 kN (2205 lbf). The LDS SPA-K series offers Class-D rated performance, delivering maximum power with minimal energy waste for lower operating costs.
These switching power amplifiers are engineered for medium-force vibration test systems. Their modular and scalable design allows for easy, economical power capacity expansion to meet future needs without complete unit replacement. The system maintains operation at reduced capacity during module failures.
