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.
