The new B&K Precision Regulated 28 A DC Power Supplies 1689 and 1690
offer multiple DC output terminals; two pairs of 3 A, snap-in DC connectors are
easily accessible on the front panel, and a pair of 28 A screw-on DC output
terminals are located on the rear panel. Both models provide their maximum
current output continuously hour after hour without thermal drifting. They are
ideal car battery substitutions for servicing or demonstrating high power car
stereo, cellular phone products, or even ham radio.
