WUFP-40 Four-Block Wi-Fi Universal Power Controller

WUFP-40 Four-Block Universal Wi-Fi Loco/Power Controller

Available Now for Immediate Shipment!


This Wi-Fi Universal Power Block Controller provides Wi-Fi Control of four isolated track power blocks and also allows you to drive DC locomotives within those blocks using Wi-Fi as well as WifiTrax equipped locos or DCC locos using a separate controller. It allows you to control the direction and source of the power supply to each block and detect a locomotive operating within the block. It supports two loco control channels that you may control with our free Loco Operator App for Windows 10 or Android.

WUFP-40 Four-Block Universal Wi-Fi Power Controller

Use this module to drive DC, WifiTrax or DCC locomotives on the same layout!

This module can be easily installed on any scale model railroad where there is a requirement to divide the track into isolated blocks or districts. This is necessary when you want to include reversing loops, wyes or turntables on your model railroad or in this case to allow you to run DC locomotives on the same layout as WifiTrax Locomotives or DCC locomotives and with the same Loco Controller app on your tablet or phone.

This module supplies power to four fully (both rail) isolated blocks on your model railroad track and allows you to control the source and direction of power to each as well as monitor current and detect and protect from overloads. The module will supply the block with either fixed DC suitable for WifiTrax-equiped locomotives, Pulse Width Modulated signal to drive a DC loco, or a DCC signal from an external DCC controller. It also provides auto-reverse to allow a locomotive to seamlessly traverse a return loop, wye or turntable.

The key feature distinguishing the WUFP-40 Universal Power Block Controller is that any one DC locomotive within the block can appear exactly like a locomotive fitted with a WifiTrax Loco Controller.

Use this when you cannot or don't want to install a WifiTrax controller in the locomotive, but you DO want to control it using Wi-Fi, such as in N-Scale where the loco may be too small.

Fully compatible with DCC systems. 15 Volt DC mains power adapter sold separately.

Note: When driving a DC locomotive the WUFP-40 uses back e.m.f from the motor to give precise control of speed and give you a speedometer readout. However, you can only control one DC locomotive on each block at a time.
