Description

A range of digitally controlled, switch-mode amplifiers used to drive electrodynamic shakers with force ratings of at least 89 kN (20,000 lbf) for vibration testing and other applications. Available with outputs from 70 to 280 kV Specifically designed to supply LDS® V900 high-force shakers with the signal they require to perform at optimal levels, these amplifiers combine strength, efficiency and adaptability. Featuring a Class-D rating, they deliver maximum power with minimal energy waste and lower running costs. Compatible with third-party vibration systems and suitable for multi-shaker applications, LDS® DPA-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. USE SCENARIOS Driving LDS® high-force shakers V964, V984 and V994 Driving third-party shakers with ratings of at least 89 kN (20,000 lbf) CHARACTERISTICS Power output range from 70 to 280 kVA Can be uprated in increments of 8 kVA by adding extra power modules Over 90% energy-efficient Full-power frequency range Low distortion, wide bandwidth (20Hz to 3kHz @ -3dB), and signal-to-noise ratio better than -68dB Peak-current rating of 3-sigma to ISO standards Optional remote control panel with reach of up to 200 metres (656 feet) Configurable interlocks for comprehensive system-monitoring and safe shutdown
