1902B

The 1902B from B&K Precision is a bench top switching DC power supply with 1V to 60V variable output voltage and 0A to 15A variable output current. It is a laboratory grade power supply with high current output in a small, lightweight form factor. The 1902B 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 1902B suitable for a wide range of applications requiring high current including production testing, telecommunications, R&D, service and university labs.

• Front panel 5A auxiliary output and maximum output power of 900W
• AC voltage range from 100VAC to 120VAC (60Hz)
• Saves up to three user defined voltage and current presets for quick recall

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.
