Keithley 2303 DC Power Supply

Overview

The Keithley 2303 is a high-speed DC power supply with integrated readback capability, designed for automated testing of portable, battery-operated devices. It provides flexible voltage and current options—0-15V at 3A or 0-9V at 5A—enabling efficient power delivery across a wide range of portable device applications while maintaining precise power monitoring.

With 100nA current resolution, the 2303 enables monitoring of ultra-low sleep mode currents, critical for validating battery life and power optimization in mobile and portable electronics. Its fast transient response simulates actual battery behavior, and the ability to sink current allows testing of battery chargers and related circuitry under realistic conditions.
