The B&K Precision 1900 is a laboratory grade switching DC power supply with high current output in a small, lightweight form factor. The 1900 provides high output voltage or high output current and feature rotary encoder control knobs, which make setting voltage and current fast and precise. Its dual action push button allows the user to set both coarse and fine, voltage and current levels. In addition to constant voltage (CV) and constant current (CC) modes, the high efficiency DC power supply offers 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 analog remote control function allows the output power, voltage, and current to be adjusted without touching the front panel of the power supply. Specifications.
