Models 1790, 1791, 1794, 1795 & 1796 are cost-effective, high power, regulated DC power supplies.
These linear power supplies are high power workhorses that will easily deliver clean power to your
high-current circuits. Special features include the ability to set constant current with no load and remote
sense to compensate for any voltage drop in load leads.
Features & Benefits
■Constant voltage (CV) and constant current
(CC) operation
■High stability and excellent regulation
■Separate output ON/OFF switch
■Remote sensing
■External analog programming interface
