Keithley 2304A High Speed Precision Power Supply, 20V, 5A, 100W

The Keithley 2304A Power Supply provides both voltage control and power consumption monitoring for automated testing of portable, battery-operated devices. The Keithley 2304A Power Supply is optimized for testing battery-operated, wireless communication devices such as cellular phones that undergo substantial load changes for very short time intervals. The Keithley 2304A Power Supply exhibits outstanding voltage stability during pulse load changes and can simultaneously measure load currents, even if they are short pulses. In addition, the Keithley 2304A Power Supply can sink current and, thus, take on the characteristics of a discharged, rechargeable battery for testing chargers and charger-control circuitry.
