GWInstek’s PSU-series fulfills low voltage (6V) and high current demands (800A) http://www.saelig.com/category/psu-series.htm

GWInstek’s PSU-Series power supplies are single output programmable switching DC power supplies covering a power range up to 1520W. Five models provide 6V to 60V and can even be connected in series (max. 2 units) or in parallel (max. 4 units) for additional capacity for higher voltage or higher current output applications.

The PSU-Series’ Constant Voltage / Constant Current selection is a very useful safety feature for protecting a Device Under Test (DUT). The power supply normally operates in constant voltage (CV) mode when the power supply is turned on.  If connected to a capacitive load, this could cause a high inrush current or current-intensive load at the power output on stage.  The PSU-Series can run in constant current to limit a current spike to protect the DUT from the inrush current damage.

The Over-voltage (OVP) and Over-current (OCP) protection prevent the DUT damage. Both OVP and OCP levels can be selected the range of 10% to 110%, with the default level set at 110% of the power supply’s rated voltage /current. The PSU-Series provides USB Host /Device , LAN, RS-232 with RS-485 and Analog Control Interfaces as standard. A LabView driver is also available for rear-panel external control of Power On/Off and external monitoring of the power output voltage and current.
