Keithley 2303 Fast Transient Response Power Supply

The Model 2303 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.

• Optimized for battery-powered device testing
• Ultra-fast transient response to load changes
• 5A continuous output
• Pulse peak, average, and baseline current measurements
• 100nA DC current sensitivity
• 45W output (15V @ 3A, 9V @ 5A)
• Sinks up to 2A

Development and testing of portable, battery-operated products, such as cellular and cordless telephones, mobile radios, and pagers.
