QDCM800
Summary: 3-Axis Gradient Amplifier System, 800 Volts, 600 Amps
Reliability, Bandwidth, Stability, Repeatability, Low THD, Low Noise, Slew Rate...
This is what is needed for fast, clear MRI images for the most demanding protocols and what the QDCM800 delivers in a compact, water cooled, cost effective package: Ingenuity and Quality from one company, Performance Controls, Inc.
In addition, the QDCM800 is based upon the field proven technology of PCI’s QDCM1400, which provides reliability combined with low meantime-to-service and yields low service cost and low total cost of ownership.
The QDCM800 is a pulse width modulated, digitally controlled gradient amplifier system that contains three 800 VDC, 250 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 700 mm wide with an 1890 mm height and 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.
