INVERTERS: WF-5220 Inverter Series

Product Description

WF-5220 Inverter Series

WFCO’s 2000-watt WF-5220 inverter delivers outstanding performance. The internal transfer system automatically allows the AC input to bypass the inverter when the inverter is connected to an AC power source. Other important features include pure sine wave output, providing the hi-tech filtering needed
for premium electronics and refrigerators, plus an easy hi-pot testing design that allows hi-potting output circuits through the inverter. With over a decade of inverter manufacturing, WFCO knows what is essential. Reliability, clean signal, easy installation, and intelligent power management make the WF-5220 the best choice in RV inverters.
