4. Setup
Proper setup is crucial for the performance and longevity of your JFA 200a Storm Lite Power Supply.
4.1. Unpacking and Inspection
- Carefully remove the unit from its packaging.
- Inspect the unit for any signs of physical damage. If damage is found, do not proceed with installation and contact your dealer.
- Ensure all accessories (if any) are present.
4.2. Mounting Location
- Choose a dry, well-ventilated location, away from direct sunlight, heat sources, and moisture.
- Ensure there is sufficient space around the unit for proper airflow, especially around the cooling fan.
- Mount the unit securely to prevent movement or vibration.
4.3. Electrical Connections
WARNING: Disconnect the vehicle's battery negative terminal before making any electrical connections to prevent short circuits.
- AC Input Connection: Connect the power supply to a suitable AC mains outlet (90 to 140Vac or 170 to 240Vac). The unit features automatic bivolt detection.
- DC Output Connection:
- Connect the positive (+) output terminal of the JFA Storm Lite to the positive (+) terminal of your automotive amplifier or battery.
- Connect the negative (-) output terminal of the JFA Storm Lite to the negative (-) terminal of your automotive amplifier or battery, or to a good chassis ground point.
- Use appropriate gauge wiring for the current draw to prevent overheating and voltage drop.
- Remote Turn-On (if applicable): If your amplifier requires a remote turn-on signal, ensure it is connected correctly.
5. Operating Instructions
Follow these steps to operate your JFA 200a Storm Lite Power Supply.
5.1. Powering On/Off
- Ensure all connections are secure.
- Connect the AC power cord to the mains outlet. The "LIGADO" (ON) indicator on the control panel should illuminate.
- To power off, disconnect the AC power cord.
5.2. Selecting Output Voltage
The JFA Storm Lite allows selection of various output voltages to suit different applications:
- Use the "AJUSTE DE SAÍDA" (Output Adjustment) knob on the control panel to select the desired base voltage: 12.6V, 13.0V, 13.4V, 13.8V, 14.0V, or 14.4V.
