The BK 1690 Regulated Digital 28A High Current DC Power Supplies are designed for continuous duty and are ideal for substituting car batteries.
The 1690 is designed for servicing/demonstrating high power car stereos, cellular phone products, camcorders, and ham radios. Hobbyists, retailers, and service shops use car batteries that are heavy, leak acid, spark, can't tolerate shorted outputs, and must be recharged.
The BK Precision 1690 power supply and related models solves these problems and are the only bench top dc power supplies in their price range built to withstand continuous duty. This dc power supply provides maximum current output continuously without overheating.
