Gradient Amplifiers

IECO has been designing and manufacturing gradient amplifiers since 1994. Over the years IECO has delivered more than 1000 amplifier systems worldwide to its customers. Amplifiers are utilized in resistive, superconductive and permanent magnet MRI systems, both in human and research scanning systems.

IECO gradient amplifiers have modular design so they can be flexibly matched to a wide range of gradient coils concerning current and voltage. Compact amplifier units can be connected in series or in parallel in Master/Slave operation to gain output voltages up to 1100V and output currents up to 1200A. Multi coil installations can also be supported.


Amplifiers are available in the following standard cabinet configurations, or as single amplifier modules.  Amplifier cabinets include a robust AC-Unit with a power factor correction.

XPA-175-350 is IECO's newest gradient amplifier. It is very compact and has three axis in one 19 " unit (5U).
