4. Setup

4.1 Unpacking

Carefully remove the power supply from its packaging. Inspect the device for any signs of damage during transit. Retain the packaging for future storage or transport.

4.2 Placement

Place the JFA 200A X-LI on a stable, flat surface. Ensure there is adequate space around the unit for proper ventilation. Do not place it on soft surfaces that could block the fan or air vents. Avoid direct sunlight, heat sources, and areas with high humidity or dust.

4.3 Connecting to AC Power

1. Verify that your AC power source is within the acceptable range for the device: 90 to 140Vac or 170 to 240Vac (Automatic Bi-volt).
2. Connect the provided AC power cord to the input port on the power supply.
3. Plug the other end of the AC power cord into a grounded electrical outlet.

4.4 Connecting to Battery/Audio System

1. Ensure the power supply is turned off and disconnected from the AC outlet before making DC connections.
2. Connect the positive (+) output terminal of the power supply to the positive (+) terminal of your battery or audio system.
3. Connect the negative (-) output terminal of the power supply to the negative (-) terminal of your battery or audio system.
4. Ensure all connections are secure and free from corrosion. Loose connections can cause overheating or poor performance.

5. Operating Instructions

5.1 Powering On/Off

Once all connections are secure, plug the AC power cord into the wall outlet. The device will power on automatically. To turn off, simply disconnect the AC power cord from the wall outlet.

5.2 Selecting Output Voltage

The JFA 200A X-LI allows you to select from several output voltage options to suit your application. Use the control buttons on the front panel to cycle through the available voltages:

• 12.6V
• 13.0V
• 13.4V
• 13.8V
• 14.0V
• 14.4V

The selected voltage will be displayed on the digital screen.

5.3 Intelligent Charge System (ICS) and 3-Stage Charging

The device features an Intelligent Charge System (ICS) with settings for 13.8V / 14.4V cyclic charging, and a customizable 3-stage slow charge system:

• Elevation: Initial charging phase.
• Absorption: Charging at a constant voltage to fully charge the battery.
• Equalization: Balances cell voltages in a battery.

The system automatically manages the charging process to optimize battery life and performance.

5.4 Super-X Function (15V Boost)

The Super-X function allows the power supply to temporarily raise the output voltage to 15V. This provides maximum performance to connected amplifiers for short durations. Consult your amplifier's specifications before activating this function to ensure compatibility and prevent damage.

5.5 Battery Diagnosis (CCA Meter)

The JFA 200A X-LI includes an exclusive battery diagnosis function. In just 10 seconds, it can perform a real analysis of the battery's load accumulation capacity using a CCA (Cold Cranking Amps) meter. This helps assess the health and performance of your connected battery.

5.6 Understanding Display Readings

The digital display provides real-time information:

• Voltmeter: Displays the current output voltage. Accuracy: 99%.
• Ammeter: Displays the current output amperage. Accuracy: 96%.

Monitor these readings to ensure stable operation and proper charging.

6. Maintenance

6.1 Cleaning

Regularly clean the exterior of the power supply with a soft, dry cloth. Do not use liquid cleaners or aerosols. Ensure the device is unplugged before cleaning.

6.2 Ventilation Checks

Periodically check the ventilation openings and fan for any dust or debris accumulation. Use a soft brush or compressed air to gently clear any obstructions. A clear ventilation path is crucial for the intelligent ventilation system to operate effectively and prevent overheating.

6.3 Storage

If storing the device for an extended period, disconnect it from all power sources and store it in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to use the original packaging for protection.
