12 Amp Converters
Automatic three-stage charging provides superior 12-volt system performance, while maintaining the ideal charge and maintenance of your battery. WF-8712 model converters provide 12 Adc output, and a highly reliable nominal 13.6 Vdc with or without a battery. No extra filtering is required. WFCO’s three-stage battery charging results in longer battery life and is totally automatic.
Here is what 3 stage charging offers
1. NORMAL MODE (Absorption) powers all DC loads, and keeps the battery charged.
2. TRICKLE MODE (Float) is initiated when there is no significant change in current draw for 44 continuous hours, keeping the battery charged while prolonging its life.
3. FAST CHARGE MODE (Bulk) kicks in to charge the battery if it’s significantly discharged due to improper maintenance, long term storage, or significantly heavy system overloads. Bulk mode is maintained for 4 hours (max.) to prevent possible battery damage.
Normal and Trickle Modes are the only charging modes your battery should ever require when you properly maintain your battery. The WFCO Normal Mode is a powerhouse, capable of charging a fully-discharged battery in under 3 hours. Trickle Mode will keep the battery safely charged when your RV is not in use.
Some RV and battery manufacturers believe high-voltage charging can potentially damage the battery if not absolutely required. The WFCO Fast Charge (Bulk) Mode is provided for the rare times a battery needs extra power for charging.
The key to long battery life is proper maintenance. Keep the battery terminals, top, and sides clean and free from corrosion, dirt, and grime. When the RV is not in use, keep it connected to a trickle charging source that will keep the battery safely charged, or disconnect the battery completely by removing all wiring connections from the battery terminal posts.
Nominal voltage output modes are a 13.2 Vdc range "float" mode, 13.6 Vdc range "absorption" charge mode, and a 14.4 Vdc range "bulk" charge mode. Short-circuit and reverse polarity protection provides you with further reliability and peace of mind.
Complies with FCC Class B, which means that the converters do not cause interference with televisions, radios, or other signals. The 8700 Series also brings you the convenience of built-in AC and DC distribution. 30-amp main AC breaker and a total of up to three 20-amp branch AC circuits can be installed. DC circuits include LED lights that illuminate to indicate open circuits.
Measures 3-3/4 inches deep, 10-1/2 inches wide and 6 inches tall for rough opening.
