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!
