The 9800 series converter-chargers are the versatile, advanced power source solution.  Available in 35, 45, 55, 65, and 75 Amp models.  Clean, filtered and reliable DC power from the WFCO converters makes them ideal for powering RV electronics and appliances.  Works with or without a battery.

These units are so quiet; you can literally install them under your bed and never be disturbed.  The quiet cooling fan only operates when needed and is extremely quiet.

9800 series tolerate high input voltage spikes without damage to internal components.  Electronic current limiting automatically shuts down power during overload or short circuit conditions.  Externally fused for reverse polarity protection. 

All models UL and cUL listed.

*Note: Unlike many other chargers, the WFCO's Boost mode looks at the voltage of the battery bank and may not necessarily remain in the boost for the entire four hours.  This is important to prevent additional gassing if the battery bank is currently charged.
