Installation / Setup
The source does not provide specific information on installation or setup highlights such as wiring, clearances, calibration, or prerequisites.
Operation
The B+K Precision Model 1743 DC Power Supply can operate in constant voltage or constant current modes. The transition between these modes is automatic and indicated by LEDs. In constant voltage mode, users can preset a current limit, and if the load causes the current to reach this limit, the unit switches to regulating the current. In constant current mode, the voltage may be preset, and if the current drops below the regulated value due to load changes, the unit reverts to voltage regulation. The power supply features coarse and fine controls for both voltage and current adjustments, and it includes reverse polarity protection and current limiting for safety. The output is isolated from the chassis and earth ground, allowing flexible connections, including series or parallel configurations with other power supplies.
