4. Setup

4.1 Unpacking

Carefully remove the power supply and all accessories from the packaging. Verify that all components are present and undamaged:

• Wanptek APS605 DC Power Supply
• Power Cord
• Output Test Leads (Alligator Clips)
• User Manual

4.2 Input Voltage Selection

Before connecting the power supply to the AC mains, ensure the voltage switch on the rear panel is set to the correct voltage for your region (115V or 230V). Incorrect voltage selection can damage the unit.

4.3 Connecting to AC Power

1. Ensure the power supply's power button is in the OFF position.
2. Connect the provided power cord to the AC power input on the rear panel of the power supply.
3. Plug the other end of the power cord into a grounded AC outlet.

5. Operation

5.1 Powering On/Off

Press the POWER button on the front panel to turn the unit on or off. The display will illuminate when the unit is powered on.

5.2 Setting Voltage and Current

The APS605 uses high-precision encoder adjustment knobs for setting voltage and current.

1. Select Parameter: Press the VOLTAGE knob to select the voltage setting, or the CURRENT knob to select the current setting. The active digit will blink.
2. Adjust Digits: Rotate the selected knob to change the value of the blinking digit (0-9).
3. Move to Next Digit: Press the knob again to move to the next digit. Repeat until all desired digits are set.
4. Confirm Setting: After setting the last digit, press the knob one more time to confirm the setting and exit adjustment mode.

5.3 Using Memory Functions (M1, M2, M3)

The power supply allows you to save and recall three groups of frequently used voltage and current settings.

1. Saving Settings: Set the desired voltage and current. Press and hold the desired memory key (M1, M2, or M3) for approximately 3 seconds until the display indicates the setting has been saved.
2. Recalling Settings: Briefly press the desired memory key (M1, M2, or M3). The saved voltage and current values will be loaded.

5.4 Output Enable/Disable

The OUTPUT button controls the power output to the terminals. This allows you to set voltage and current without applying power to the load.

• Press the OUTPUT button to enable the output (button illuminates green).
• Press the OUTPUT button again to disable the output (button light turns off).

5.5 Over Current Protection (OCP)

The OCP function protects your load from excessive current. When OCP is active and the output current exceeds the set limit, the output will shut down.

• Press the OCP button to activate or deactivate the over current protection. When active, the button will illuminate.
• To reset OCP after a trip, disable and then re-enable the output, or cycle the power supply.

5.7 Connecting a Load

Always ensure the power supply output is disabled before connecting or disconnecting a load.

1. Ensure the OUTPUT button is off.
2. Connect the positive lead of your load to the red (+) terminal and the negative lead to the black (-) terminal.
3. If your application requires grounding, connect the ground lead to the green (GND) terminal.
4. Set the desired voltage and current limits.
5. Press the OUTPUT button to enable the power output to your load.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your power supply.

• Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Do not use abrasive cleaners or solvents. Ensure the unit is powered off and disconnected from AC mains before cleaning.
• Ventilation: Periodically check that the cooling fan and ventilation openings are free from dust and obstructions. A clogged fan can lead to overheating.
• Fuse Replacement: If the unit does not power on, check the fuse located in the fuse box on the rear panel. Replace it with a fuse of the same type and rating only. Refer to the specifications for the correct fuse type.
