Keithley's Model 2425-C 100W SourceMeterTone extends the voltage range of the 2420 to 100V, enabling 100W capability in the 1A range. Like the Model 2420 High Current SourceMeter, it also offers a 3A range with 60W power capability. The Model 2425-C was designed for production testing of medium-power devices like DC-to-DC converters, power supplies, and other components requiring between 60W and 100W of total DC power. The Contact Check function makes it simple to maximize test integrity by verifying test connections easily in just 350’s before an automated test sequence begins. This eliminates measurement errors and false product failures associated with contact fatigue, breakage, contamination, loose or broken connection, relay failures, etc.
