Operation
The manual provides operating instructions for the B+K Precision Model 1710A and 1730A DC Power Supplies, which are high-quality, general-purpose DC power sources. These power supplies offer 0-30 volts DC output, adjustable with both coarse and fine controls for precise settings. The Model 1710A provides a current output of 0-1 amp, while the Model 1730A provides 0-3 amps. They feature two current ranges, High and Low, for excellent current settability and meter resolution, with two large panel-mounted meters to continuously monitor output voltage and current.
The power supplies can operate in either constant voltage or constant current modes, with smooth and automatic crossover between the two. LEDs indicate the mode of operation. In constant voltage applications, a current limit can be preset, and when load variations cause the current to reach this limit, the unit regulates output current instead of voltage. In constant current applications, the maximum voltage can be preset, and when load variations cause current to drop below the regulated value, the unit reverts to regulated voltage operation.
The power supplies include reverse polarity protection and current limiting to prevent damage from improper connections and to protect the equipment being powered. The output is isolated from chassis and earth ground, allowing for flexible connections. The supplies can be connected in series for a 0-to-60 volt power source or in parallel for up to twice the output current. These features make the power supplies suitable for a wide range of applications, including service shops, engineering labs, production testing, school laboratories, and home use by hobbyists.

Safety & Warnings
Normal use of test equipment can expose users to electrical shock, especially when testing in areas with high voltage. An electrical shock with 10 milliamps of current passing through the heart can be fatal. Even voltages as low as 35 volts dc or ac rms are considered dangerous. To prevent contact with high voltage and to steer current away from the heart in case of accidental contact, the following precautions should be observed:
1. The dc output of the power supply poses little shock danger, but certain test conditions can create high voltage shock hazards:
a. If the equipment under test is a “hot chassis” type, a serious shock hazard exists unless the equipment is unplugged or an isolation transformer is used.
b. If the equipment under test is “powered up” and uses high voltage, the power supply outputs may be at a high potential. Do not float the power supply output to more than 100 volts peak with respect to chassis or earth ground.
c. If the equipment under test is “off” but uses high voltage, discharge high-voltage capacitors before making connections or tests.
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 danger.
3. Avoid exposing high voltage unnecessarily. Remove housings and covers only when necessary, turn off equipment while making test connections in high-voltage circuits, and discharge high-voltage capacitors after removing power.
