Order NOW! Shipping to begin August/September 2025

Ever wondered how much load your DCC system is under with all those sound equipped locos?

Well use our DCC Power Sentinel to find out!

With better that +/-1% accuracy and one second updates our meter will show you exactly how much power you are using from your system. Also shows a graph of the history of the current usage too.  What's more, the graph automatically updates and scales!

Also shows DCC voltage and peak current.

Find out how close to the rated maximum limits of your system you are!

With a maximum current of 10A this power meter is fully compatible with all known DCC systems on the market and power boosters under 10A too!

Our unique design only measures the current of your locos and accessories, not the meter itself!

Simple to wire with just four connections. Just take the wires directly from your command station into the meter then out to your track or DCC Bus. No separate power supply required. Can be added to most layouts with the minimum disruption.

Also works on DC providing the voltage is above 5VDC.

Size of module: 3.5" x 1.7" x 1" (excluding connector)

The case can be either free standing or panel mounted.

Designed and made by Hobby Trax UK.
