Programmable switching DC power supplies offer increased power density
B&K Precision introduced its new line of bench switching mode DC power supplies, models 1685B, 1687B, and 1688B. Each model offers a different configuration of variable output voltage and current: 1-60V, 0-5A (1685B); 1-36V, 0-10A (1687B); and 1-18V, 0-20A (1688B). All models provide constant voltage (CV) and constant current (CC) modes, bright 3-digit LED displays, and rotary encoder control knobs for precise coarse and fine voltage and current settings. Complemented with a compact form factor and low cost, these DC power supplies are practical for use in university labs, R&D, service, and production testing. The reduced-size design of these switching power supplies has increased power density and provides high efficiencies of 80 percent or more.
