Keithley 2304A High Speed Precision Readback Power Supply

The Model 2304A Power Supply provides voltage control and power monitoring for automated testing of portable, battery-operated devices. It delivers up to 5 A to handle portable device loads easily, while 100 nA resolution enables precise monitoring of sleep mode currents with 0.2% basic accuracy. Fast transient response simulates battery behavior, with output returning to within 100 mV of the set voltage in 40 µs or less.

The ability to sink current to 3 A enables the 2304A to simulate the characteristics of a discharged, rechargeable battery for testing of battery chargers and charger-related circuitry. In addition to DC current measurements, it can measure current pulses as short as 60 µs and as long as 833 ms.
