B&K Precision 1900B Datasheet & Stock

The 1900B from B&K Precision is a bench top switching DC power supply with 1V to 16V variable output voltage and 0A to 60A variable output current. It is a laboratory grade power supply with high current output in a small, lightweight form factor. The 1900B provides various configurations of high output voltage or high output current. It features 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, this high efficiency DC power supplies offer preset and remote control modes. The analogue remote control function allows output power, voltage and current to be adjusted without touching front panel of power supply. These features make 1900B suitable for a wide range of applications requiring high current including production testing, telecommunications, R&D, service and university labs.

Footnotes
Before connecting the line cord to AC mains, check rear panel AC line voltage indicator. Applying a line voltage other than indicated voltage can destroy AC line fuses.

Warnings
The device can be damaged by ESD. To avoid damage, be sure to follow proper procedures for handling, storing, transporting parts & subassemblies which contain ESD sensitive components.
