The WIENER MARATON is a highest density Power Supply for Hostile Environment,  low noise, floating low voltage power supply system. The MARATON-Series has been designed  to power lowest noise electronics with medium to high currents (10A to 600A current range) over long distances in sensed ore impedance controlled mode. Dynamic behavior is foreseen to set internally for short or long sensed distances. MARATON  MAgnetism and RAdiation TOlerant New Different versions for moderate or agressive  Hostile Environment are available  Radiation hard and magnetic field tolerant, tested up to 14krad / 5,6 x 1012n/cm2 / 3 x 1012p/cm2  and 1300G Modular, high density design for greatest flexibility, up to 12 channels (55A/300W max each) in a 3 U high chassis Low noise switching power supply, floating DC outputs with sense lines / impedance control Input options: 385 VDC or 230/400VAC (47-440Hz) Water-cooling for highest DC power Intelligent, non-active or external controller Immanent construction conditiond output voltage limiting
