The BK Precision 1711 is a dual-range DC power supply delivering 0–60 VDC at 0–2 A continuous output. Built for laboratory, educational, and industrial test environments, it combines precise voltage and current regulation with dual-mode operation (constant voltage and constant current) and comprehensive protection. The front panel hosts two large analog meters, coarse/fine voltage controls, and selectable current ranges—High (0–2 A) and Low (0–0.5 A)—for optimized resolution across applications. Automatic CV/CC crossover with LED status indication simplifies setup and load testing. Line and load regulation holds to ≤0.01% + 3 mV in CV mode, while current limiting adjusts from 5% to 100% of maximum. Reverse polarity, overvoltage, and short-circuit protection guard against common faults. A pre-regulator reduces dissipation at lower output voltages, extending operating life. The unit accepts 120, 220, 230, or 240 VAC input and operates from 0 to +40 °C at ≤75% RH, with full-load rating to +25 °C.
