KEITHLEY 2304
The Keithley 2304 Power Supply is expertly designed for voltage control and power consumption monitoring in the automated testing of portable, battery-operated devices. This versatile power supply is particularly optimized for wireless communication devices, such as cellular phones, which experience rapid load changes over brief time intervals. With exceptional voltage stability during pulse load alterations, the Keithley 2304 also has the capability to simultaneously monitor load currents, even during short pulses. Notably, this power supply can sink current, simulating the behavior of a discharged, rechargeable battery, making it ideal for testing chargers and charger-control circuits.
