Amplifiers for Unholtz-Dickie, Thermotron & more

Keep your vibration testing equipment at peak performance and maintain up-time with replacement amplifiers from ETS Solutions.  The ETS Solutions MPA series amplifier family is a wide frequency band digital switching (Class D) Power Amplifier designed with the latest state-of-the-art technology. A number of built-in features in the amplifier allow vibration testing to be simple and easy.  The MPA amplifier series are made for continuous operation with each configuration adaptable to any existing air-cooled or water-cooled electrodynamic shaker. Amplifier outputs range from 1 kVa to 360 kVa.

By upgrading from older inefficient amplifiers to the new MPA Series Power Amplifiers operators benefits the latest technology can offer. Older shaker systems are revived and the equipment’s useful life extended.

The MPA Series amplifier operates at over 92% efficiency; nearly double the efficiency of older amplifiers. Benefits include space savings as the amplifiers are smaller in size, air-cooled so heat exchangers are not required and significantly less power consumption due to higher efficiency levels. ETS Solutions amplifiers are built with reliable, COTS (commericial off the shelf components).

ETS replacement amplifiers are matched and plug-compatible to the vibration testing equipment to ensure no loss in performance or compatibility. ETS amplifiers work with any make and model shaker: Unholtz-Dickie (UDCO), Ling, Thermotron, LDS & MB Dynamics.
