Digit Systems has entered production on its first Kepler Series product. The flagship MPS2 MRI ramping power supply is now available for pre-order. It incorporates a number of technological breakthroughs to achieve a very high power density, unparalleled precision and many unique MRI application features.To achieve our goals, we revisited the fundamental concepts of power converter designs. A single 25kg package now incorporates: - Auto-ranging input stage: 200VAC to 480VAC - Output stage: 1000A -- +/-18VDC -- Galvanically isolated -- 4Q operation - 18 Ch., active shim output: +/-100A -- +/-18VDC on each channel - Dissipation Stage: 4kW -- Controlled in temperature, power and voltageKey MRI specific features: - Magnetically safe design. Can be operated inside the MRI room - Compatible with any MRI on the planet out of the box - 5ppm /hour. typical current stability. Minuscule ripple and noise. - 1uV, 0.1mA control resolution on all outputs and all modes - Bi-directional power flow allows the supply to power itself from the superconductive coil in case of incoming AC loss. - Fully automated ramp process, configurable ramp profiles, precisely controlled energy flow into and out of the superconductive coil at all times, Custom cryostat temperature monitoring system.
