Model 1689, 1690

Regulated 28A DC Power Supply

The new B+K Precision Regulated 28A DC Power Supplies 1689 & 1690 offer

multiple DC output terminals; two pairs of 3A, snap-in DC connectors are easily

accessible on the front panel, and a pair of 28A 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.

B+K 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!
