The Digitrax PS615 is the 90 watt power supply Digitrax ships with its Evolution starter sets, and the one to reach for whenever a command station or booster needs a full 5 amps at the rails. It puts out 15V DC at 6 amps from a universal 100-240V input, so it works on any household supply, and it replaces the older PS514. Setting up or expanding a DCC layout? Browse our DCC Accessories, DCC Wiring, and DCC Decoders. Features 90W output - 15V DC at 6 amps, enough headroom to run any Digitrax command station or booster at its full 5 amp rating. Universal 100-240V AC input at 50/60Hz, so it works anywhere and accepts standard IEC cord sets. Full galvanic isolation between the AC input and the DC output, plus built-in overcurrent and overload protection. Power indicator LED so you can see at a glance that the supply is live - useful when you are chasing a dead section. Meets MEPS VI and DOE VI efficiency standards and is built to RoHS requirements. Direct replacement for the discontinued Digitrax PS514, and the supply included in the EVO, EVOD, EVOX and EVOXD Evolution sets. More Information Brand Digitrax Item Number PS615 Product Type DCC Power Supply Output 15V DC, 6 A Rated Power 90 W Input 100-240V AC, 1.2 A, 50/60 Hz Cord Accepts standard IEC cord sets Protection Overcurrent, overload, full galvanic isolation Indicator Power LED Replaces Digitrax PS514 Scale All scales Condition New FAQ Which Digitrax systems does the PS615 power?It is rated for Digitrax command stations and boosters running at 5 amps, and it is the supply Digitrax includes with the Evolution starter sets (EVO, EVOD, EVOX, EVOXD). Check your unit manual for its required input voltage before connecting. Can I use it to replace my old PS514?Yes.

Digitrax Digitrax SP26158B | 26.5x15.5x9mm 8 Ohm Box Speaker - Sealed Enclosure & Bare Wires | Multi Scale
The Digitrax SP26158B is a 26.5 x 15.5 x 9mm 8 ohm speaker that arrives already mounted in its own sealed enclosure - the part most installers end up fabricating by hand. That box is what turns a thin, tinny cone into a locomotive that actually sounds like one, and at 9mm deep the whole assembly still slides into HO hoods, tenders and O scale frames. Looking for more DCC sound gear? Browse our DCC Speakers, DCC Decoders, and DCC Accessories. Features Sealed enclosure included. No scratch-building a baffle from styrene - the speaker ships in a purpose-made box that stops the rear wave cancelling the front wave. 26.5 x 15.5 x 9mm footprint fits HO diesel hoods, steam tenders and O scale frames where a 28mm round speaker will not clear. 8 ohm, 1/2 watt - matches the speaker output on most DCC sound decoders. Bare interface wires for soldering straight to the decoder speaker pads. For the same speaker with a 2-pin plug, see the Digitrax SP26158BC. Rectangular box shape sits flat against a shell wall or floor, which is usually easier to pack than a round cone plus baffle. More Information Brand Digitrax Item Number SP26158B Product Type DCC Sound Decoder Speaker with Enclosure Speaker Shape Rectangular box Dimensions 26.5 mm x 15.5 mm x 9 mm Impedance 8 Ohm Power 1/2 Watt Enclosure Included, sealed Connection Bare interface wires (no plug) Recommended Scale HO, O, G Condition New FAQ What is the difference between the SP26158B and the SP26158BC?They are the same speaker and enclosure. The SP26158B has bare interface wires that you solder to the decoder. The SP26158BC ends in a 2-pin plug for decoders and motherboards that take a plug-in speaker. Do I still need to build a baffle?No. That is the point of this version - the enclosure is already there and sealed. Just mount it somewhere it is not blocked and keep the opening clear of the shell. Will it work with my sound decoder?Any DCC sound decoder rated for an 8 ohm speaker output, Digitrax or otherwise. If your decoder manual specifies 32 ohms, use a 32 ohm speaker such as the Digitrax SP531832B instead. How much room do I need?Just over an inch long, roughly 5/8 in. wide and 3/8 in. deep. That fits most HO diesel long hoods and tenders. For N scale, use the 13mm SP13138 or the oval SP10188.

Digitrax Digitrax TSMK | Terminal Strip Mounting Kit
The Digitrax TSMK is the adapter between signals you already own and a Digitrax signal system. Two terminal strip boards, with the current-limiting resistors already on them, take bare wires from your existing signals on screw terminals at one end and accept a standard signal driver cable at the other - so you keep the signals you have built or bought and still drive them properly. Signalling your layout? Browse our DCC Accessories, DCC Wiring, and the full Digitrax range. What's Included Item Qty Terminal strip board with resistors 2 Features Connects existing signals to a DCC signal system without replacing the signal bases you have already installed. Resistors already fitted on the board - no current-limiting maths and no risk of over-driving an LED. Each board handles 1 to 4 signal heads, so a single board can serve a mast with several heads or a group of simple signals. Screw terminals at the signal side - run your existing wires in and tighten, no soldering. Plug a standard signal driver cable into the other side and the signals join the rest of the system. More Information Brand Digitrax Item Number TSMK Product Type Terminal Strip Mounting Kit Scale All scales Contents 2 terminal strip boards with resistors Capacity 1 to 4 signal heads per board Signal Connection Screw terminals System Connection Digitrax signal driver cable Condition New FAQ What problem does this solve?You already have signals on the layout - scratch-built, from another manufacturer, or installed before you went to DCC signalling - and you want to drive them from a signal decoder without pulling them out and starting again. Do I still need resistors for my LEDs?No. The current-setting resistors are on the board already, which is most of the value of the kit. How many signals will one kit handle?Two boards, each covering one to four signal heads, so up to eight heads per kit depending on how they are arranged. What else do I need?A signal decoder to drive the aspects and a signal driver cable to reach the boards - the SDCK kit provides the cable and sockets.

Digitrax Digitrax DHWHPS | 9 pin to DCC medium plug short harness (1”)
The Digitrax DHWHPS is the short adapter harness that turns a 9-pin Digitrax decoder into a plug-in one. Roughly an inch of wire between the 9-pin decoder socket and an 8-pin NMRA medium plug - just enough to reach, and short enough that there is no spare loop to hide in a cramped HO shell. Building a DCC fleet? Browse our DCC Decoders, DCC Wiring, and DCC Accessories. Features 9-pin Digitrax socket to 8-pin NMRA medium plug - lets a bare-socket decoder such as the DH127D drop into a DCC-ready locomotive. Approximately 1 in. of wire, deliberately short for tight installs where excess harness is the problem. No soldering - the decoder plugs into one end, the locomotive socket takes the other. Standard NMRA 8-pin medium plug, so it fits the socket used in most DCC-ready HO locomotives. A spare harness is also useful when the original is damaged or when you move a decoder between locomotives. More Information Brand Digitrax Item Number DHWHPS Product Type DCC Decoder Wire Harness Scale HO Decoder End 9-pin Digitrax Locomotive End 8-pin NMRA medium plug Wire Length Approx. 1 in. Condition New FAQ Do I need this harness?Only if your decoder has a bare 9-pin socket and your locomotive has an 8-pin DCC-ready socket. Decoders sold with a plug already fitted, such as the DH127P or DH127PS, do not need one. How short is "short"?About an inch. That is the point of this version - in a cramped shell a longer harness just becomes wire you have to fold and hide. If you need more reach, use the standard-length harness instead. Which decoders does it fit?Any Digitrax decoder with the 9-pin harness socket, such as the DH127D. Which way round does the plug go?The 8-pin plug is keyed by pin 1, which is marked on both the plug and the locomotive socket. Line the markings up - a plug fitted 180 degrees out will run the loco backwards or leave the lights wrong.

Digitrax Digitrax UR90X | LocoNet Infrared Receiver | Multi Scale
The Digitrax UR90X is a fascia panel with an infrared receiver built in, so compatible Digitrax throttles can be operated untethered - point the throttle at the panel and keep walking. It also works as an ordinary universal panel, with a front throttle jack, two rear LocoNet jacks for daisy-chaining, and indicator LEDs that tell you at a glance whether LocoNet is alive and whether the receiver is seeing your throttle. More LocoNet gear? Browse our DCC Accessories, DCC Wiring, and the full Digitrax range. Features Infrared receiver for cordless operation with compatible Digitrax IR throttles - no cable trailing behind the operator. One RJ12 throttle jack in the front panel so a tethered throttle can still plug in at the same spot. Two rear RJ12 LocoNet jacks for daisy-chaining the panel onwards around the layout. IR and NET indicator LEDs - immediate feedback on whether LocoNet is live and whether the panel is receiving. All connections plug-detachable, which simplifies hookup, maintenance and fault-finding. Power sharing charge circuitry for throttles across up to six universal panels (an external 12V supply is required for DT602 and UT6 charging in sleep mode). More Information Brand Digitrax Item Number UR90X Product Type LocoNet Infrared Receiver Panel Scale All scales Throttle Jacks 1 x RJ12, front panel LocoNet Jacks 2 x RJ12, rear Indicators IR and NET LEDs Cable Type 6-conductor with RJ12 connectors Optional Power External 12V DC for throttle charging in sleep mode Condition New FAQ What is the difference between the UR90X and a plain universal panel?A universal panel such as the UP7 gives you throttle jacks and LocoNet connections. The UR90X adds an infrared receiver, so a compatible IR throttle can be used without plugging in at all. Which throttles work cordlessly with it?Digitrax throttles with infrared capability. A tethered throttle plugs into the front jack as normal, so the panel is useful either way. How many do I need?Infrared is line-of-sight, so plan one within sight of each operating position rather than spacing them by distance alone. Around a curve or behind a backdrop, the signal will not reach. Do I need a separate power supply?Not for normal operation - LocoNet powers the panel. A 12V DC supply is only needed if you want throttle charging to continue while LocoNet is asleep.
