2303

The Keithley 2303 is a 45W High-Speed Battery Simulating DC Power Supply designed for testing battery-operated, wireless communication devices. It is optimized to provide outstanding voltage stability during fast pulse load changes, such as those found in cellular devices. It features precision readback of load currents (including short pulses), is capable of sinking current to simulate a discharged battery, and offers a continuous output of 15V at 3A or 9V at 5A.
