Product Description：
The Keithley 2304A is a 100 W high-speed programmable DC power supply optimized for dynamic-load testing of battery-powered devices in R&D, production and QA. Its fast-transient architecture recovers the output voltage to within 100 mV of the set value in 40 µs, accurately emulating real battery behavior under pulsed loads. Combined with 100 nA-level current resolution and 3 A current sinking, it enables one-stop testing of sleep currents, peak pulse currents and charge performance for cell phones, wearables and IoT terminals.
