QDCM1400
Specifications: 1000 - 1400 Volt / 600 Amp 3-Axis
The QDCM1400A-LN is a pulse width modulated gradient system that contains three 1400 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. The power amplifier has been tested for EMC when operated as part of an imaging system.
