The WF-9540 model provides 40 Amps and a clean, constant 13.6 VDC nominal output for reliable operation of electronics and appliances. Automatic three-stage charging extends the life of your battery with output voltage modes of 13.2 VDC range “float” mode, 13.6 VDC range “absorption” mode, and a 14.4 VDC range “bulk” charge mode. The 9500 Series also maintains peace and quiet, as the cooling fan runs only when needed.

Exclusive choice of three DC circuit connection modes – Quick Connect Terminals, Screw Terminals, or Wire Pigtails – allows installers to select their preferred wiring connection for speed and ease of installation. Additionally, the 9500 Series features a zero-clearance, front ventilation system so there is no wasted space around the unit.

Every model is designed to comply with FCC Class B, which means that the converters do not cause interference with televisions, radios, or other signals. The 9540 model also brings you the convenience of built-in AC and DC distribution. Two 50 Amp main AC breakers and a total of up to twelve AC branch circuits, when using duplex breakers, can be installed. Seventeen DC branch circuits, including three 30 Amp and fourteen 20 Amp, have LED lights that illuminate to indicate open circuits.
