Operation
The manual provides operating instructions for the B+K Precision Model 1710A and 1730A DC Power Supplies. These power supplies can be used in constant voltage or constant current applications, with a smooth and automatic crossover between the two modes. LEDs indicate the mode of operation: “CV” for constant voltage and “CC” for constant current. In constant voltage mode, a current limit can be preset, and if load variations cause the current to reach this limit, the unit will regulate the output current instead of the voltage. In constant current mode, the maximum voltage can be preset, and if load variations cause the current to drop below the regulated value, the unit will revert to regulated voltage operation at the preset value. The output is isolated from chassis and earth ground, allowing for flexible connections. Two supplies can be connected in series for a 0-to-60 volt power source or in parallel for up to twice the output current.

Safety & Warnings
Normal use of test equipment can expose users to electrical shock hazards, especially when testing in areas with high voltage. An electrical shock with as little as 10 milliamps of current passing through the heart can be fatal. Even voltages as low as 35 volts DC or AC rms can be dangerous under certain conditions. It is important to follow accepted safety practices to avoid contact with high voltage and to prevent current from passing through the heart in case of accidental contact.
Specific safety precautions include:
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 has a “hot chassis,” 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 floated to the potential at the point of connection. High voltage may appear unexpectedly in defective equipment. 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 and uses high voltage in normal operation, 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.
3. Avoid unnecessary exposure to high voltage. Only remove housings and covers when necessary. Turn off equipment while making test connections in high-voltage circuits and discharge high-voltage capacitors after removing power.
