Controls & Indicators
The front-panel controls and indicators of the Model 1711A 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 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 output voltage at the value set by the voltage controls.
3. Coarse Control: Used for coarse adjustment of output voltage, with the value read on the voltmeter.
4. Fine Control: Used for fine adjustment of output voltage, with the value read on the voltmeter.
5. 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 High-Low switch.
6. High-Low Switch: Selects the current range. The high position selects a high current range with values read on the top meter scale of the ammeter (0 to 2A), while the low position selects a low current range with values read on the bottom meter scale of the ammeter (0 to 0.5A).
7. ON-OFF Switch: Controls the power supply’s power state.
8. “+” Terminal (Red): Positive polarity output terminal.
9. Ground Terminal (Green): Earth and chassis ground terminal.
10. “-” Terminal (Black): Negative polarity output terminal.
11. A Meter: Reads output current in amperes, using the top scale when the High-Low switch is set to High and the bottom scale when set to Low.
12. V Meter: Reads output voltage on a 0 to 64 V scale.
