BK1902B

The BK1902B from B&K Precision is a 1900B series laboratory grade high power switching DC power supply with high current output in a small form factor and lightweight package. The 1900B series provide various configurations of high output voltage or high output current and feature rotary encoder control knobs which makes setting voltage and current fast and precise. Its dual action push button allows user to set both coarse and fine, voltage and current levels. In addition to constant voltage and constant current modes device offers a unique solution with its preset and remote control modes. Save up to 3 different presets of voltage and current values for quick recall. The remote control function allows output power, voltage and current to be adjusted without touching front panel. A remote sensing terminal is also available to compensate for voltage drop across load leads. It is suitable for a wide range of applications including telecommunications and university labs.

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.

Notes

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.
