1. Prodotto finitoview
The WF-9800 Series converter/chargers are adaptable, advanced power source solutions. The WF-9865 model provides 65 Amps of clean, reliable DC power, which is ideal for powering electronics and appliances. The 9800 Series provides clean power, even without filtering from a battery. Quiet operation is assured as the cooling fan runs only when needed. Another advantage is FCC Class B compliance for the WF-9865 model, which means that the converter does not interfere with televisions, radios, or other signals. Automatic three-stage battery charging maintains your battery’s life with three nominal voltage output modes: 13.2 VDC “float” mode, 13.6 VDC “absorption” mode, and a 14.4 VDC “bulk” charge mode. Electronic current limiting automatically shuts down the power during overload or short-circuit conditions.

4.4 Istruzioni per il cablaggio
- Ingresso CA: Collegare il 20 Amp AC power cord to a suitable 105-130 VAC, 60 Hz power source. Ensure the AC circuit is properly fused or has a circuit breaker.
- Uscita CC: Connect the positive (POS+) and negative (NEG-) DC output terminals to your RV's 12V DC distribution panel or directly to the battery. Observe correct polarity.
- Collegamento della batteria: Connect the converter to your battery bank. The unit features automatic three-stage ricarica della batteria.
- Messa a terra: Assicurarsi che l'unità sia correttamente collegata a terra secondo le normative elettriche locali.
- Montaggio: Securely mount the converter/charger to a flat, stable surface using appropriate fasteners. Allow for adequate airflow around the unit.
5. Istruzioni per l'uso
Once properly installed and connected, the WF-9865-AD-CB operates automatically to provide stable DC power and charge your battery.
5.1 Tre-Stage Ricarica della batteria
The converter/charger features an automatic three-stage battery charging system to optimize battery life:
- Bulk Mode (14.4 VDC): This mode provides a rapid charge to bring a discharged battery up to approximately 90% capacity.
- Absorption Mode (13.6 VDC): Once the battery reaches 90% capacity, the voltage drops to 13.6 VDC to safely complete the charging process.
- Float Mode (13.2 VDC): When the battery is fully charged, the converter switches to float mode, maintaining a trickle charge to prevent overcharging and keep the battery topped off.
5.2 Funzionamento del ventilatore
The cooling fan operates only when needed, ensuring quiet operation. The fan will activate automatically when the internal temperature rises due to load or charging activity.
5.3 FCC Class B Compliance
The WF-9865 model is FCC Class B compliant, meaning it is designed to minimize interference with televisions, radios, and other electronic signals.
6. Manutenzione
Una manutenzione regolare contribuisce a garantire la longevità e le prestazioni ottimali del convertitore/caricabatterie.
- Pulizia: Periodically clean the exterior of the unit and ensure ventilation openings are free from dust and debris. Use a soft, dry cloth. Do not use liquid cleaners.
- Ispezione del fusibile: Regularly inspect the 40 Amp automotive-type fuses on the rear panel (refer to Figure 2). If a fuse is blown, replace it only with a fuse of the same type and rating. Blown fuses often indicate a short circuit or overload condition.
- Connessioni: Check all electrical connections periodically to ensure they are secure and free from corrosion.
- Ventilazione: Ensure that the area around the converter/charger remains clear to allow for proper airflow and cooling.
7. Risoluzione Dei Problemi
This section provides solutions to common issues you might encounter with your WF-9865-AD-CB converter/charger.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| No DC Output Power | No AC input power; Blown DC fuses; Overload/Short circuit condition. | Check AC power source and circuit breaker. Inspect and replace DC fuses (refer to Figure 2). Disconnect loads to check for short circuits; the electronic current limiting feature will automatically shut down power during these conditions. |
| La batteria non si carica correttamente | Loose battery connections; Faulty battery; Converter in float mode. | Check battery terminal connections for tightness and corrosion. Test the battery's health. Ensure there is sufficient load to trigger bulk or absorption mode if the battery is low. |
| Forte rumore della ventola | High load on the converter; Restricted airflow; Dust buildup in fan. | This is often normal under heavy load. Ensure adequate ventilation around the unit. Clean any dust from the fan and vents. If noise is excessive and constant without high load, contact support. |
| Unit Shuts Down Automatically | Overload or short circuit on DC output. | The electronic current limiting feature has activated. Disconnect all DC loads, then reconnect one by one to identify the faulty appliance or wiring. Correct the issue before restoring power. |
