5. Power ON/OFF switch
6. C.C. Indicator (Constant current mode indicator)
7. C.V. Indicator (Constant voltage mode indicator)
8. Coarse voltage regulator (To coarsely adjust output voltage)
9. Fine voltage regulator (To slightly adjust output voltage)
10. Coarse current regulator (To coarsely adjust output current)
11. Fine current regulator (To slightly adjust output current)
12. Negative output terminal
13. Ground output terminal
14. Positive output terminal
15. Concealed fuse box→Open the back cover to get to the fuse.

Operation

Please strictly follow the instruction to avoid machine malfunction or possible injury caused by electricity.

Constant Voltage Mode (C.V. Mode)

1. Connect the three-wire power cord with a US AC outlet.
2. Turn all knobs (Coarse Voltage Regulator, Fine Voltage Regulator, Coarse Current Regulator, Fine Current Regulator) anti-clockwise to minimum position before using.
3. Press the power switch. The power indicator (red LED) on the front panel will automatically light.
4. Turn the Coarse Current Regulator clockwise to maximum position until the C.V. indicator lights up.
5. Turn the Coarse Voltage Regulator and Fine Voltage Regulator clockwise to that you are desirous of the output voltage value.
6. Always press the power switch and shut it off before connecting the positive output terminal and negative output terminal with a load or similar component. Then switch it on.
7. The output voltage will be displayed. Current can’t be changed in C.V. Mode.NOTE: The working mode is decided by the load current and the traction current. In Constant Voltage Mode, the current is determined by the load. Large Load, small current. In Constant Current Mode, the voltage is determined by the load. Small load, small voltage.

If you assume there is a big difference between the output voltage and the set value, use a multimeter to check it.

Constant Current Mode (C.C. Mode)

1. Connect the three-wire power cord with a US AC outlet.
2. Turn the Coarse Voltage Regulator clockwise to the maximum position and the Coarse Current Regulator and Fine Current Regulator anti-clockwise to the minimum position.
3. Connect the positive output terminal and the negative output terminal with a wire (one included) and bring it to a short circuit.
4.  Press the power switch to turn it on. The C.C. indicator lights up, which means it’s on C.C. Mode.
5. Turn the Coarse Current Regulator and Fine Current Regulator clockwise to that you are desirous of output current value.
6. The output current will be displayed. Voltage can’t be changed in C.C. Mode.

NOTE: The working mode is decided by the load current and the traction current.In Constant Voltage Mode, the current is determined by the load. The larger the load, the smaller the current.In Constant Current Mode, the voltage is determined by the load. The smaller the load, the smaller the voltage.If you assume there is a big difference between the output voltage and the set value, use a multimeter to check it.

Maintenance

Repair

Do not attempt to repair or service your instrument unless you are qualified to do so and have the relevant calibration, performance test, and service information.

Replacing the Fuse

Turn off the power switch, remove the power line cord from the power socket and disconnect the test leads at output terminals before replacing the fuse. Replace it only with the same type of fuse.

Cleaning

To clean the DC Power Supply, use a soft cloth dampened in a solution of mild detergent and water. Do not spray cleaner directly onto the device, since it may leak into the cabinet and cause damage. Do not use chemicals containing benzine, benzene, toluene, xylene, acetone, or similar solvents. Do not use abrasive cleaners on any portion of the power supply.
