7224 POWER AMPLIFIER

7224 amplifier

 

The World's First Cost-Effective DC - 300kHz Power Amplifier

7224 voltage potential vs. frequency

Features

The 7224 power amplifier offers the power and features of larger industrial amplifiers in a new smaller 2U size that runs from single phase 120/230VAC. It features DC - 300 kHz bandwidth, controlled current or controlled voltage modes of operation and has a wide range of field configurable options.

The 7224 is typically used to create waveforms found in EMC standards like CS2009, DO-160, MIL STD 461, and as a gradient amplifier for very small bore, high-gain MRI and NMR systems. Optional "P" version offers precision control of output offset, DC drift and gain linearity.
