The B+K Precision Model 1680 DC Power Supply manual provides instructions for setup, operation, and troubleshooting, including details on connecting equipment, measuring output voltage and current, and protecting against overloads. It emphasizes safety precautions to prevent electric shock and equipment damage, advising users to avoid overloading and ensuring proper ventilation during use.
Manual Overview
The B+K Precision Model 1680 DC Power Supply manual provides detailed instructions for troubleshooting, diagnostics, and maintenance to ensure optimal performance and longevity. The power supply delivers a regulated output of 13.8 volts DC, suitable for powering automotive accessories outside of vehicles. It features a continuous output current of 4 amps and a peak of 6 amps, with protection against overloads, short circuits, and reverse polarity. Troubleshooting involves checking the output voltage and current using a multimeter, ensuring that the load does not exceed the specified limits to prevent overheating and potential damage. The manual emphasizes the importance of not overloading the power supply, as severe overloads can cause the output voltage to drop significantly, indicated by the power LED turning off. For moderate overloads, the power supply may overheat, necessitating a cooling period. Safety precautions include using a polarized 3-wire outlet to reduce shock risk and ensuring adequate ventilation to prevent internal heat build-up.
Quick Issues Covered
- Diagnose power-up failures by checking OPERATE indicator illumination.
- Measure output voltage with multimeter across OUTPUT terminals.
- Use schematics for circuit tracing during severe overload conditions.

Installation / Setup
The source provides information on the setup of the B+K Precision Model 1680 DC Power Supply. It highlights the importance of using a polarized 3-wire AC outlet to ensure the power supply chassis and case are grounded, reducing the risk of electrical shock. The power supply should not be used in ambient temperatures above 40°C (104°F) and requires sufficient air space for effective cooling, with a recommended two-inch space at the sides and a six-inch space at the top and rear. The heat sink and vent should not be blocked, and objects should not be placed on top of the power supply. The power supply has a regulated output of 13.8 volts DC, suitable for powering automotive accessories. It includes binding posts and a cigar lighter socket for output connections, with a total current demand not exceeding 4 amps continuous or 6 amps peak if both are used simultaneously. The power supply is protected against severe overloads, such as short circuits, and has a current foldback overload protection feature.
Operation
The BK Precision Model 1680 DC Power Supply operates with a regulated output of 13.8 volts DC, suitable for powering automotive accessories outside of vehicles. To use the power supply, connect the equipment to the output terminals or the cigar lighter socket, ensuring the polarity is correct. Turn on the power supply using the POWER switch, which will illuminate the OPERATE indicator. The equipment can then be powered on. When using both the binding posts and the cigar lighter socket simultaneously, ensure the total current does not exceed 4 Amps continuous or 6 Amps peak. To prevent overload, monitor the current and avoid exceeding 4 Amps for extended periods. If an overload occurs, the power supply may overheat or lose regulation, indicated by a drop in output voltage or a loud buzz in audio equipment. Measure output voltage by connecting a multimeter across the output terminals and output current by connecting a multimeter in series with the load.

Safety & Warnings
The manual provides several safety warnings and precautions:
1. Use only a polarized 3-wire outlet to ensure the power supply chassis and case are connected to a good earth ground, reducing the danger of electric shock.
2. There is little danger of electric shock from the power supply output, which produces a maximum of 13.8 volts DC. However, if the power supply output is connected to an external high voltage, there may be a significant risk of electrical shock. Exercise caution, especially if the equipment being powered contains high voltage.
3. If the power supply output is floated (referenced to a voltage rather than earth ground), turn off the power supply and the equipment under test when making connections. Never float the power supply to a voltage greater than 100 volts peak with respect to ground.
4. Avoid using the power supply in ambient temperatures above +40°C (104°F). Ensure sufficient air space at the rear, top, and side vent openings for effective airflow to prevent internal heat build-up. Typically, a two-inch space at the sides and a six-inch space at the top and rear of the power supply is adequate. Do not block the heat sink on the rear or the vent on top of the power supply, and do not place objects on top of it.
5. Overloading the power supply may burn it out, which is considered misuse and is not covered under warranty. The power supply is self-protected against severe overloads, such as accidental short circuits, connection to defective equipment, or loads requiring more than 7 amps. In such cases, the equipment will likely not operate, and the output voltage will drop significantly below 13.8 volts, causing the POWER LED indicator to go off.
6. For moderate overloads (greater than 4 amps but less than 7 amps), the equipment being powered will operate normally, but the power supply will overheat. Loads greater than 4 amps should be limited to 5 minutes duration, followed by at least 10 minutes for cooling before reuse. If the power supply “smells” hot or the heat sink is too hot to touch, it should be cooled by removing the load. An overload of about 6 or 7 amps may cause loss of regulation and extremely high ripple in the output, which can produce a loud buzz in most audio equipment. If a loud buzz is heard, reduce the load or use a power supply with a higher current rating.
