The legacy QDCM800, 3-Axis Gradient Amplifier has been replaced by the newer product(s) below, which we invite you to consider.

If you currently use this legacy product, PCI can help with transitioning to a newer version solution. If repair or replacement is needed, PCI will be happy to assist.

QDCM800, 3-Axis Gradient Amplifier (Legacy)

The QDCM800 is a pulse width modulated, digitally controlled gradient amplifier system that contains three 800 VDC, 220 Arms, 600 Apk amplifiers and a mains isolated power supply, intended for use in precision control systems. The amplifier operates from 380-480 VAC, 50-60 Hz three-phase mains connected power and provides a precisely controlled, high fidelity output current. The amplifier and power supply are water-cooled and packaged in a cabinet 27.5 inch (700 mm) wide with a 62.0 inch (1575 mm) height and 37.4 inch (950 mm) depth. This power amplifier has been designed to operate in a control room environment and has been tested for EMC compliance when operated as part of an imaging system.

As with all of the PCI products, we will partner with our clients to customize the QDCM800 to meet the requirements for form, fit and function.
