Engineered to keep
your locomotives moving

The NXT StayOn uses professional-grade components and a sophisticated hardware soft-start circuit to deliver reliable keep-alive performance — without the compromises found in cheaper alternatives.

01
🔌
Hardware Soft-Start

The Texas Instruments TPS22810 IC manages inrush current in hardware — not via a passive RC circuit. This means consistent, reliable protection against booster shutdowns across all operating conditions.

02
✂️
Configurable Size

Each board can be cut at designated positions to reduce its footprint — giving up to six configurations per product. Fits tight N scale tank engines and large H0 express locomotives alike.

03
📦
Full Capacity Out of the Box

No expansion packs to buy. The NXT StayOn ships with all capacitors fitted and ready to go — maximum keep-alive performance from the moment you install it.

04
🎛️
Decoder Stays Programmable

The soft-start circuit prevents capacitor recharging from interfering with your DCC system. Your decoder remains fully programmable on the programming track at all times.

05
🌍
Universal DCC Compatibility

Rated to 20V DC — comfortably above the 18V DCC maximum. Compatible with Digitrax, ESU, Roco z21, NCE, Lenz, ZIMO, and all other DCC systems currently available.
