Overview
No Frills, just the power you need for large scale trains. The “No Frills Track Throttle” simply controls the speed
and direction of large scale track powered locomotives. It is used in conjunction with a low cost industrial power
supply to provide up to 10 amps at 7-28 volts to your track, which will easily handle your largest locomotives and
consists.
PWM (Pulse Width Modulation) output is provided for extra torque during slow speed operation. Output is protect-
ed with an internal replaceable 10A fuse.
Choose your own DC power supply (purchased separately), up to 28V. It must be a filtered and regulated power
supply, not a simple transformer. Power supply voltage will determine your maximum speed.
We recommend:
Meanwell LRS-150-24 (24V, 6.5A) available from multiple on-line sources for about $18
Note: Keep in mind that most locomotives only require about 1 amp while running. A power supply capable of 3-5
amps is usually more than enough for most applications. More amps won’t make it run any better. It just blows the
fuse faster (and sometimes the wiring in your train) when you get a short (as in a derailment).
You can also use a laptop style AC Power adapter. Ours provides 19V, 6.32A with a DC Power connector that
plugs into the 2.5mm DC power jack next to the terminal strip. Any power adapter with a 5.5m o.d. / 2.5mm i.d.
DC connector can be used.
Installation
Wiring
Input power
Connect your power supply to either the 7-28V terminals or the DC
input jack (but not both). Connections to the terminal strip are easily
done with spade lug terminals or stranded wire that has been tinned.
Wiring between the Track Throttle and your power supply should be at
least 16 AWG. Output wiring to your track, the bigger the better to re-
duce voltage drops. 16 AWG or heavier (smaller AWG number).
Connections to an industrial power supply should be done using
spade or ring lugs crimped onto the wire ends. Wire to wire connec-
tions can be done with wire nuts or solder joints. You may be required
to supply your own AC cord for the power supply.
