Typical Constant Voltage Operation - BK Precision 1760A Manual De Instruccion

Typical Constant Voltage Operation

1. Before connecting the device to be powered to the power
supply, determine the maximum safe load current for the
device to be powered and set the current limit value (see
"Setting Current Limit" procedure in this section).
2. Set Fine VOLTAGE control
VOLTAGE control to minimum (fully counterclockwise).
3. Turn off power supply and connect it to the device to be
powered (see "Hook-Up" procedure in this section).
4. Turn on POWER switch. The C V indicator should light.
5. Set the meter selection switch to the V position to select the
voltage metering mode.
6. Increase the VOLTAGE setting until the LED display reads
the desired value. The Fine control permits easier setting to a
specific value.
7. Set the meter selection switch to the A position to select the
current metering mode and note the load current on the
display.
8. If the load current exceeds the preset current limit, the CV
indicator will go off and the CC indicator will light. In this
case, the power supply automatically switches to the constant
current mode and further rotation of the VOLTAGE control
will not increase the output voltage.
