Keithley 2303 Power Supply

The Keithley 2303 Power Supply is designed for voltage control and power monitoring tailored for automated testing of portable, battery-operated devices. Boasting an impressive output of up to 5A, the Keithley 2303 efficiently handles demanding portable device loads. Features such as 100nA resolution enable precise monitoring of sleep mode currents, ensuring a 0.2% basic accuracy that is crucial for product reliability.

This power supply simulates battery behavior with its fast transient response, returning to within 100mV of the set output voltage in just 40μs. Furthermore, it can sink current, effectively mimicking the characteristics of a discharged rechargeable battery, making it ideal for testing battery chargers and related circuitry. In addition to providing DC current measurements, the Keithley 2303 excels at measuring current pulses with a range from 60μs to 833ms.
