Keithley 2303-PJ High Speed Precision Readback Power Supply, 45W, 500mA

The Keithley 2303-PJ High Speed Precision Readback Power Supply provides both voltage control and power consumption monitoring for automated testing of portable, battery-operated devices. This 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 2303-PJ 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 2303-PJ Power Supply can sink current and, thus, take on the characteristics of a discharged, rechargeable battery for testing chargers and charger-control circuitry. To capture low current pulses from very low power devices, the Keithley 2303-PJ Power Supply provides pulse measurement on both the 5A and 500mA ranges.
