B&K Precision - BK Precision 1901B-220V Switching DC Power Supply, 220V, 1-30V. Model 1901B-220V - 01BK1901-220V

Models 1900B, 1901B, and 1902B are laboratory grade switching mode DC power supply with high current output in a small form factor and lightweight package. The supplies provide various configurations of high output voltage or high output current and make setting voltage and current levels fast and precise through its dual action, coarse/fine rotary encoder control. In addition to constant voltage (CV) and constant current (CC) modes, the high efficiency DC power supplies offer a unique solution with its preset and remote control modes. Save up to three different presets of voltage and current values for quick recall. The remote control function allows the output power, voltage, and current to be adjusted without touching the front panel of the power supply. A remote sensing terminal is also available for use to compensate for long output line losses.
