5.2.2 Constant Current Operation
1. In constant current mode, the power supply regulates the output current at the selected value,
while the voltage varies with the load requirement.
2. While the power supply is operating in constant current mode, the CCLED on the front panel
illuminates.
3. Adjustment of the output current limit can be made when the power supply output is enabled
(Output On) or disabled (Output Off).
- Disabled output (Off): Press V/I CHK button and then rotate the Current encoder knob. The
CURRENT meter will show the programmed constant current made for 5 seconds after the
adjustment has been completed. Then the VOLTAGE meter will display "OFF".
- Enabled output, power supply in Constant Voltage mode: Press the V/I CHK button and then
rotate the CURRENT encoder knob. The CURRENT meter will show the programmed constant
current made for 5 seconds after the adjustment has been completed, and then will return to
show the actual load current.
- Enabled output, power supply in Constant Current mode: Rotate the CURRENT encoder knob
to adjust the constant current made.
4. Adjustment resolution can be set to Coarse or Fine adjustment. Press the FINE button to select
between the Coarse and Fine resolution. The FINE LED turns On when the resolution is set to
FINE.
5.2.3 Automatic Crossover
If the power supply operates in Constant Voltage mode, while the load current is increased to
greater than the constant current made setting, the power supply will automatically switch to
Constant Current mode. If the load is decreased to less than the current limit setting, the power
supply will automatically switch back to Constant Voltage mode.
5.3. OVER VOLTAGE PROTECTION (OVP)
The OVP circuit protects the load in the event of a remote or local programming error or a power
supply failure. The protection circuit monitors the voltage at the power supply sense points and thus
providing the protection level at the load. Upon detection of an Over Voltage condition, the power
supply output will shut down.
