BK Precision 1688A 13.8 V, 21 AMP, DC Power Supply
* BK Precision 1688A Features:
o 20 A guaranteed at 13.8V -Current limiting overload protection
o Thermostatically controlled cooling fan
o Operates continuously at full load without overheating
o Connect two in parallel for more current
o Connect two in series for higher voltage
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
The BK 1688A is a high quality 3 to 14 Volt DC Power Supply primarily designed for bench powering of automotive and marine electronic equipment.
THE METER WINDOWS HAS A SMALL TINY LINE IN THE UPPER RIGHT CORNER (YOU CAN HARDLY SEE IT) OTHER THAN THAT THE UNIT LOOK GREAT, AND WORKS GREAT.......
The 1688A has a maximum output current proportional to the voltage setting, the maximum current of 20 amps available from 13.8 to 14 volts and is reduced to 4.5 amps at 3 volts. There are two panel mounted meters that continuously monitor the output voltage and current.
