Description

Choose a Testkey TK6900 wide-range DC power supply by its voltage, current and power ratings. The nine configurations provide one output with a 200 W, 360 W or 600 W power limit. Maximum voltage and maximum current are constrained by the selected model’s rated power envelope.

Choose the voltage ceiling and required current, then verify that the test operating point fits the selected model’s 200 W, 360 W or 600 W limit. Compare the accuracy and ripple rows when selecting a supply for precision measurements.
