BK Precision 1635 DC Power Supply

The BK Precision 1635 is a DC power supply designed for general-purpose laboratory and industrial applications. It offers a continuously variable output voltage from 0 to 30 VDC and a current output adjustable from 0 to 3 A. The unit features a 3-1/2 digit LED display for monitoring output voltage, output current, or an external DC voltage up to 199.9 V. It incorporates a pre-regulator for reduced internal power dissipation and improved reliability, along with overload and reverse polarity protection. The power supply operates in either constant voltage (CV) or constant current (CC) modes, with automatic and smooth crossover between them.
