Available with outputs ranging from 8 to 56 kVA, these switch-mode power amplifiers are used to drive electrodynamic shakers with force ratings of at least 9.81 kN (2205 lbf), such as LDS V830.Request Price
Similar to the LDS® DPA-K range, these switching power (or switch-mode) amplifiers have been designed to power our medium-force vibration test systems. They have a Class-D rating, offering maximum power with minimal energy waste and, thus, lower running costs.
Compatible with third-party shakers, LDS® SPA K amplifiers are modular and scalable, allowing you to easily and economically increase their power capacity to meet future needs without having to replace the entire unit. This modular approach also ensures power continues to be delivered to the shaker system even if a module fails, allowing operation at lower force until the module is replaced.
