1688A产品概述
These High Current DC Power Supplies are designed for continuous duty and are ideal for substituting car batteries. For servicing/demonstrating high-power car stereos, cellular phone products, camcorders, and ham radios. Hobbyists, retailers, and service shops use car batteries to power mobile equipment. Car batteries are heavy, leak acid, spark, can’t tolerate shorted outputs, and must be recharged. These Power Supplies provide their maximum current output continuously hour after hour without overheating. For more output, just connect two or more in parallel or series. These are the only high-current supplies in their price range built to withstand continuous duty!
Models 1686A & 1688A are a high quality 3 to 14 Volt DC Power Supplies primarily designed for bench powering of automotive and marine electronic equipment. The Models 1686A &1688A have a maximum output current proportional to the voltage setting (see specifications chart). Two panel mounted meters continuously monitor the output voltage and current.
