The Series 2281S Battery Simulator and Precision DC Power Supply innovatively integrates battery simulation with the functions of a high-precision power supply and battery testing. It's able to analyze the DC consumption of a device under test, test a battery, generate a battery model based on the battery charging process, and simulate a battery based on the battery model. The 2281S-20-6 can output voltage and current up to 20V and 6A and sink current up to 1A.
