Output Power, Voltage and Current Capability
PowerFlex
PowerFlex technology enables the instrument to achieve full instrument output power across
the majority of the voltage range. 3A current limit, limits power at absolute voltages < |8.33V|.
Absolute voltages above |21V| are only achievable on the SMU4201. Output current limited to
0.5A at absolute voltages > |21V|.
