WFCO 9990 Converter Amp Draw

The power factor (probably 0.7, same as the PDs') will make that input 1450w, actually requiring 2,071 VA from the power source (generator or pedestal)

2071/108 volts (for the 120v) = 19a.

Which is why a 90 amp (DC) charger that is not power factor corrected needs a 20a (AC)circuit breaker and #12 wire. The PD 9280 does too, and it has 80 DC amps, not 90.

BTW, the PowerMax 100 amper is power factor corrected and so it can run on a 15a circuit. So can the WFCO 98100.

mbopp- thanks for pointing that out to me. I can't believe I missed that earlier when looking at the website.

Manufactures website says 13.8A, 1450 watts.

Well the answer would depend on what cycle the converter is running at any given time - bulk, absorption, or float and of course will also vary according to the battery's constantly changing state of charge. Sorry, I'm not sure how I could better answer your question ... perhaps a call to Best Converter would yield a more definitive answer.

Does anyone know how many amps the WFCO 9990 draws when connected to shore power.

Under what conditions? ... no load, full load, what? :@
