Replacement Amplifiers

Designed for continuous operation with any electro-dynamic shaker

The ETS Solutions MPA series amplifier family is a wide frequency band digital switching (Class D) Power Amplifier designed with 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 or new air-cooled / water cooled electro-dynamic shaker. Amplifier outputs range from 1 KVA to 300 KVA.

The ETS Solutions HVA Series Switching Amplifier is an efficient, air cooled, modular high-power solid state (Class D) Amplifier designed for continuous operation in vibration testing when used with appreciate Shaker and instrumentation. It applies to various inductive or resistive loads.  Amplifier provides power outputs from 60 kVA to 480 kVA to match the power requirements of Shaker. Each power module provides 60 kVA.
