DC/DC power supply GB350

Powerbox’s GB350 buckconverter module is the first building block in its category that is able to operate safely when exposed to high radiation magnetic fields of 2 to 4 Tesla. GB350 delivers an output power of 350W and when higher power levels are required it can be paralleled using an interleaving mode thus reducing EMI. Modern MRI systems usually generate 1.5 to 4 Tesla, making conventional power supplies using ferrite material useless due to inductance saturation as a result of the MRI magnet disturbing the energy transfer. To prevent parasitic saturation, power supplies are traditionally positioned outside the shielded operation room. Installing the power supplies remotely requires long cables with subsequent power losses, and it is also a big challenge to power the latest generation of measuring equipment that require stable and tightly regulated voltages under fast transient load conditions.
