Controls & Indicators
The front-panel controls and indicators of the B & K-Precision Model 1611 DC Power Supply include:
1. C.C. (Constant Current) Indicator: A red LED that lights up in constant current mode, indicating that the unit is regulating the output current at the value set by the current controls.
2. C.V. (Constant Voltage) Indicator: A green LED that lights up in constant voltage mode, indicating that the unit is regulating the output voltage at the value set by the voltage controls.
3. Voltage Controls:
– Coarse Control: Allows for coarse adjustment of the output voltage, with the value read on the voltmeter.
– Fine Control: Allows for fine adjustment of the output voltage, with the value read on the voltmeter.
4. Current Controls:
– Current Control: Adjusts the current limit in constant voltage mode and the constant current value in constant current mode. The range of adjustment is determined by the HI-LO switch.
5. HI-LO Switch:
– HI position selects the high current range, with the value read on the top meter scale of the ammeter.
– LO position selects the low current range, with the value read on the bottom meter scale of the ammeter.
6. Power Controls:
– ON-OFF Switch: Turns the power supply on or off.
7. Output Terminals:
– “+” Terminal (Red): Positive polarity output terminal.
– GND Terminal (Green): Earth and chassis ground.
– “-” Terminal (Black): Negative polarity output terminal.
8. Meters:
– A Meter: Reads output current in amperes, using the top scale when the HI-LO switch is set to HI and the bottom scale when the switch is set to LO.
– V Meter: Reads output voltage on a 0 to 52 V scale.

Operation
The B & K-Precision Model 1611 DC Power Supply can be used in constant voltage or constant current applications. The crossover between these modes is smooth and automatic, with LED indicators showing whether the unit is in constant voltage (CV) or constant current (CC) mode. In constant voltage mode, a current limit can be preset, and if load variations cause the current to reach this limit, the unit switches to regulate the current. In constant current mode, the voltage can be preset, and if load variations cause the current to drop below the regulated value, the unit reverts to voltage regulation. The power supply features two current ranges, HI and LO, for better current settability and meter resolution. It also includes reverse polarity protection and current limiting to protect both the power supply and the equipment being powered. The output is isolated from chassis and earth ground, allowing for flexible connections. Two power supplies can be connected in series for a 0-to-100 volt power source or in parallel for up to twice the output current.

Safety & Warnings
Use only a polarized 3-wire ac outlet. This assures that the power supply chassis, case, and ground terminal are connected to a good earth. Although the power supply is protected against reverse polarity damage, the circuit being powered may not include such protection. Always carefully observe polarity; incorrect polarity may damage the equipment under test.
