NCE SB5 Smart Booster (5 Amp)

The NCE SB5 Smart Booster is a powerful expansion for your NCE Power Cab DCC system, designed to deliver more power and greater flexibility for larger model railway layouts. With a full 5 Amps of continuous track power, it enables you to run multiple trains and accessories smoothly and reliably.

Unlike the basic Power Cab, once connected to the SB5, your Power Cab can be unplugged and used as a true walk-around throttle, no need to keep it docked for the system to operate 

The SB5 also allows the use of up to 6 cabs (addresses 2–7), each with up to six recalls, and supports expansion with additional NCE boosters (DB5) for even larger layouts
