Keithley Instruments: Model 2303 / 2304 Battery Simulating DC Power Supplies

Overview   The Model 23032303/2304A2304A Power Supplies provide both voltage control and power consumption monitoring for automated testing of portable, battery-operated devices. These DC power supply products are optimized for testing battery-operated, wireless communication devices such as cellular phones that undergo substantial load changes for very short time intervals. These power supplies exhibit outstanding voltage stability during pulse load changes and can simultaneously measure load currents, even if they are short pulses. In addition, this family of power supplies can sink current and, thus, take on the characteristics of a discharged, rechargeable battery for testing chargers and charger-control circuitry.   Both the 100W Model 2304A2304A and the 45W Model23032303 can supply 5A (at 20V for the Model 2304A and 9V for the Model 2303) to serve the peak pulse loading requirements of battery-operated devices. In both instruments, the maximum current of 5A can be delivered continuously. The Model 2304A can supply up to 20V DC while the Model 2303 can supply up to 15V.   Key Applications: Automated test applications, ATE systems in R&D, design validation, and manufacturing.
