Regulated 28A DC Power Supplies
Model 1689 & 1690
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.
■ 1VDC to 15VDC Variable Output
■ 28A Output at ≥13.5VDC
■ Overload protection
■ High RFI stability
■ Multiple DC Output Terminals.
These B+K high current DC power supplies are designed for continuous
duty and are ideal substitutes for car batteries in applications such as
servicing/demonstrating high-power car stereos, cellular phones,
camcorders, and ham radios. Hobbyists, retailers, and service shops use
car batteries to power mobile equipment. Car batteries are heavy, can’t
tolerate shorted outputs, and must be recharged.
These Power Supplies provide their maximum current output without
overheating. For higher output, just connect two or more in parallel or
series. These are the only high-current supplies in their price range built
to provide continuous duty.
Variable Voltage - 3 to 14 volts DC
