BK Precision 1630 DC Power Supply

The BK Precision 1630 is a versatile single-channel DC power supply designed for a wide array of electronics testing and development applications. This unit offers both constant voltage (CV) and constant current (CC) operation with automatic crossover, indicated by front-panel LEDs. It features coarse and fine adjustment controls for precise voltage and current settings, along with two distinct current ranges (High and Low) for enhanced resolution at lower current levels. The BK Precision 1630 includes integrated analog meters for continuous monitoring of output voltage and current. Protection features such as reverse polarity and adjustable current limiting safeguard connected equipment and the power supply itself. Additionally, the output is isolated, allowing for flexible grounding configurations or floating to external voltages. Two units can be interconnected in series for higher voltage output or in parallel for increased current capacity.
