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.
