The B+K Precision 9103 Programmable Multi-Range DC Power Supply, 42V/20A, 320W automatically recalculates voltage and current limits for each setting, providing 320 W output power in any voltage/current setting within the supply's rated voltage and current limits. This model features auto cross-over for constant voltage (CV) and constant current (CC) operation, 3 voltage/current presets for frequently-used settings and transient operation, and versatile remote control modes. The dual action push button allows the user to set both coarse and fine voltage and current levels quickly and precisely. A remote sensing terminal compensates for voltage drop across load leads.
