The manual for the B&K Precision Model 1635 DC Power Supply provides detailed instructions on setup, operation, and troubleshooting, including safety precautions, operating instructions for constant voltage and current applications, and maintenance guidelines such as fuse replacement and line voltage conversion. It also highlights features like LED indicators for monitoring, overload protection, and reverse polarity protection to ensure safe and efficient use.
Manual Overview
The B&K Precision Model 1635 DC Power Supply is designed for various electrical applications, providing a 0-30 VDC output with a current range of 0-3 amps. It features both constant voltage and constant current modes, with automatic crossover between the two. The unit’s LED display can monitor output voltage, current, or an external voltage up to 199.9 volts. For troubleshooting, the manual emphasizes the importance of understanding error codes and diagnostics, particularly in relation to maintaining the correct voltage and current settings. Calibration and adjustments are facilitated by coarse and fine controls for precise voltage settings and adjustable current limits from 5% to 100% of the maximum output. The power supply includes reverse polarity protection and overload protection to prevent damage. The output is isolated from the chassis and earth ground, allowing flexible connections. For board-level guidance, the manual suggests using the pre-regulator to minimize internal power dissipation and ensure reliability. The unit’s design is compact and portable, suitable for use in service shops, engineering labs, and educational settings.
Quick Issues Covered

Safety & Warnings
Normal use of test equipment, such as the DC power supply, can expose users to electrical shock hazards, especially when testing near exposed high voltage. Electrical shocks with currents as low as 10 milliamps can be lethal. Voltage as low as 35 volts DC or AC rms is considered dangerous and can produce lethal currents under certain conditions. The manual advises adopting work habits that prevent contact with high voltage and steer current away from the heart in case of accidental contact. Specific precautions include:
1. The DC output of the power supply poses little shock risk, but certain test conditions can create high voltage shock hazards:
a. A serious shock hazard exists with “hot chassis” type equipment unless it is unplugged or specific precautions are followed.
b. If the equipment under test is powered and uses high voltage, the power supply outputs may float to the potential at the connection point. High voltage may appear unexpectedly in defective equipment. Do not float the power supply output to more than 500 volts peak with respect to chassis or earth ground.
c. If the equipment under test is off and uses high voltage, discharge high-voltage capacitors before making connections or tests, as some circuits retain high voltage long after being turned off.
2. Use only a polarized 3-wire AC outlet to ensure the power supply chassis, case, and ground terminal are connected to a good earth ground, reducing shock risk.
