WF-8740LiS Power Center *

WFCO’s proven WF-8740LiS Power Center now offers a Lithium Switch version with the WF-8740LiS Power Center. The Lithium Switch allows customers the versatility to change charging modes between lead-acid and lithium batteries by simply hitting a switch. Easy to use, the WF-8740LiS Power Center provides a convenient, cheaper, long-term option that eliminates the hassle of swapping out a whole unit.

The WF-8740LiS Power Center is our smallest and lightest power center. Still, it’s big on benefits such as reliability, ease of installation, space efficiency, WAGO Connectors, and the ideal number of DC circuits.

Every WF-8740LiS Power Center complies with FCC Class B, which means that the converters do not cause interference with televisions, radios, or other signals. The WF-8740LiS Power Center also brings you the convenience of built-in AC and DC distribution, a 30 amp main AC breaker, and a total of up to three 20 amp branch AC circuits. DC circuits include LED lights that illuminate to indicate open circuits.
