Features

Model 3601 Ultra Low Noise, Modular, Rack Mount Power Supply

Overview The MIL-Systems Model 3601 ultra low noise, rack mount, modular power supply has been devel-oped for signal processing and amplifier applications where ultra low noise and system up-time are critical requirements. The Model 3601 chassis can accommodate up to three modules with 6 output connectors per module. Each output connector has two outputs, giving a total of 12 out-pus per module. Each module can be “hot-swapped” while the remaining modules in the chassis continue to provide uninterrupted power. Modbus serial line communications provide for indi-vidual on-off control of each output as well as feedback of status, current draw, temperature and hours of operation. An optional fan assembly provides additional cooling for continuous opera-tion up to 50 0C.

Images show unit configured with one module and no optional fan assembly fitted.
