BK Precision 1791 DC Power Supply

The BK Precision 1791 is a 640W single-channel, linear regulated DC power supply designed for applications requiring clean and reliable power. Its robust construction and high-performance specifications make it suitable for electronic circuit design, testing, and service environments. This power supply offers both constant voltage (CV) and constant current (CC) operation, providing flexibility for various testing scenarios. Key features include high stability, excellent regulation, and the ability to preset output voltage and current limits. Additionally, it includes a separate DC output ON/OFF switch for added control and a remote sensing facility to compensate for voltage drops in the load leads. The unit can be operated on a benchtop or mounted in a standard 19-inch rack.
