Part Number
WF-9855, WF-9855-MBA, WF-9855-AD-MBA, WF-9855AN
Specification
DC output voltage (no load) approx.: 14.6/13.6/13.2V
Fan control: proportional
Bulk Mode (Quick Charging Voltage): 14.4V DC. Output: 55 Amps DC. Input: 105-130 VAC, 60 Hz, 940W. Provides 55 amp DC power, ideal for powering electronics and home appliances
AC Input: Voltage: 120 Vac, 60Hz, Current: 11 A, DC Output: 55 Amps, Automatic three-stage battery charging maintains your battery’s life with 3 nominal voltage output modes: 13.2 VDC range “float” mode, 13.6 VDC range “absorption” mode, and a 14.4 VDC range “bulk” charge mode. Suitable for both lithium batteries and lead-acid batteries.
Function
Charges battery or powers 12V equipment
Exact replacement for WF-9800
"Switch mode" type: 3-stage charging and fixed single output modes series
Temperature controlled quiet internally mounted fan cooling
Reverse polarity, overload, and thermal protection
Works with both lead batteries and lithium batteries
Includes LED indicator light
Can also be wired in series or parallel to reach even higher power outputs
Feature
Quiet operation is assured as the cooling fan runs only when required by the electric load. Converter fans run cooler and more efficiently than other converter fans because the fan is activated by the load being placed on it, not by a heat sensor. Converters protect from damage if polarities are switch. Three-Stage converters replace any single stage converters. Improving your RV’s DC output. Upgrade your RV to the latest technology.
Great Compatibility
