B& K Precision’s 1 672 and 1 673 are quad display triple output DC power supplies that provide two variable outputs and one fixed output. The variable outputs can work independently, in series tracking, or parallel m ode. C onveniently adjust voltage and current with independent front panel knobs and bright quad LED display. Accessible through a sim ple push/pull switch, the 1 672 and 1 673 ’s unique series and parallel tracking features let you easily double the output voltage or current. For achieving even higher voltages or current, m ultiple units can be connected in series or parallel. Features and Benefits I Three independent outputs I Individual control knobs for voltage and current settings of variable outputs I C V (constant voltage)/C C (constant current) m ode operation I Separate 3 -digit voltage and current displays for variable outputs I LED indication for C V/C C m ode I O verload indication LED for fixed output I Series tracking and parallel tracking m ode operation to double output voltage or current respectively Triple O utput D C Pow er Supplies M odels 1672 & 1673 D ata Sheet w w w .bkprecision.comTechnical data subject to change © B& K Precision Corp. 2014 These power supplies are ideally suited for applications in electronic test, production, and service, where m ultiple independent DC power supplies are required. The 1 672 and 1 673 are both designed to operate in a constant voltage or a constant current m ode with autom atic crossover, allowing continuous transition from constant current to constant voltage m odes in response to load condition changes.
