2308 with Output Resistance
Programmed to 130 mΩ
The 2303, 2306, and 2308 have a programmable output resistance, which allows them to
simulate the output of a real battery, a capability that conventional power supplies do not
have. The voltage output response of a lithium ion battery to a load current burst is shown
in the gure on the left. The gure on the right shows the voltage output of the 2308
with its output resistance programmed to be equivalent to the internal resistance of the
Lithium Ion battery. The 2308’s output is nearly identical to the battery’s output.
Use a Series 2300 power supply to simulate a battery
and to power a battery-powered device such as a
smartphone.
