  • Page 95: How Do I Stack Channels To Output Higher Voltage

    Series 2600 System SourceMeters User’s Manual Frequently Asked Questions How do I stack channels to output higher voltage? The maximum output voltage of a Model 2601 or 2602 channel is 40.4V, and the maximum output voltage of a Model 2611 or 2612 channel is 202V. Higher volt- age can be output by stacking (connecting in series) channels.
