Safety Precautions

• Always connect the power supply to a grounded outlet.
• Do not operate the device in wet or damp conditions.
• Ensure proper ventilation around the unit to prevent overheating.
• Do not open the casing; there are no user-serviceable parts inside.
• Disconnect power before making any connections or disconnections to the output terminals.
• Observe polarity when connecting loads to the output terminals.

Setup

Unpacking and Inspection

1. Carefully remove the power supply from its packaging.
2. Inspect the unit for any signs of physical damage. If damage is found, do not operate the unit and contact customer support.
3. Verify that all accessories listed in the packing list are present.

Connecting to Power

• Ensure the power switch on the front panel is in the OFF position.
• Connect the provided AC power cord to the power input socket on the rear of the unit.
• Plug the other end of the AC power cord into a suitable grounded electrical outlet.

Connecting a Load

• Before connecting any load, ensure the power supply is turned off and the output voltage/current controls are set to their minimum values.
• Connect the positive (+) terminal of your load to the red output terminal on the power supply.
• Connect the negative (-) terminal of your load to the black output terminal on the power supply.
• If grounding is required for your application, connect the ground terminal (green) to the appropriate ground point on your load or circuit.

Operating Instructions

Turning On/Off

• To turn on the power supply, press the power switch located on the front panel. The digital display will illuminate.
• To turn off the power supply, press the power switch again.

Adjusting Voltage and Current

• Voltage Adjustment: Use the voltage adjustment knob (typically labeled 'V' or 'Voltage') to set the desired output voltage. Rotate clockwise to increase voltage, counter-clockwise to decrease.
• Current Adjustment: Use the current adjustment knob (typically labeled 'A' or 'Current') to set the desired output current limit. This acts as a current limiting feature to protect your load. Rotate clockwise to increase the current limit, counter-clockwise to decrease.

Understanding the Display

The digital display provides real-time readings of the output voltage, current, and power. It may also indicate the operating mode (Constant Voltage - C.V. or Constant Current - C.C.) and Over Current Protection (OCP) status.

Figure 2: Example of the digital display showing voltage, current, and power output readings.

Over Current Protection (OCP)

The OCP feature protects the power supply and the connected load from excessive current. If the output current exceeds the set limit, the OCP will activate, and the output may shut down or limit the current. Refer to the specific model's button layout for OCP activation/deactivation if applicable.

Maintenance

Cleaning

• Before cleaning, ensure the power supply is turned off and disconnected from the main power outlet.
• Use a soft, dry cloth to wipe the exterior of the unit.
• Do not use abrasive cleaners, solvents, or harsh chemicals, as these may damage the casing or display.
• Keep ventilation openings clear of dust and debris.

Storage

• Store the power supply in a cool, dry place away from direct sunlight and extreme temperatures.
• Protect the unit from dust and moisture when not in use for extended periods.
