SPA-K amplifiers, available for LDS air-cooled shakers from the V830 to the V8, have integral field power and blower power supplies. Featuring an economy mode and low harmonic distortion, they utilise the latest high frequency switching module from LDS. SPA-K amplifiers can be controlled either locally from a control panel with LCD display, or remotely from other equipment. 

LDS SPA-K Switching Power Amplifiers 

• Mid-range amplifiers designed for use with LDS air-cooled shakers (V830, V850, V870, V875, V895)
  Power range of 8 - 56 kVA

• Micro-processor control unit and LCD function display provides simple se t up and fast troubleshooting

• Current sharing capability better than 1% allows multiple units t o be connected in parallel with no risk of failure even under shock conditions

• Peak current rating of 3-sigma meets ISO standards

• Distortion less than 0.15% at full power

• Variable field control achieves optimum power consumption and harmonic distortion

LDS HPA-K Switching Power Amplifiers

• Dedicated 5 kVA amplifiers for use in conjunction with LDS V700 series shakers
  These compact cabinets feature the same power module, micro-processor control unit and LCD function display as the SPA-K range
