* The marker light provision is not necessary when using a QSI AM SS. Just plug into the "Marker Light" Output on the top board.
Warning, the LED leads MUST have a resistor of at lease 200 Ohms in series, to protect the micro Processor.
1) All DCRUs will accept the QSI After Market plug-in Sound Systems without any modifications.
AC powered DCRU Reverse Units for DC Motors
1.5 Volt directional light with plug in cable (for use with all DCRUs) are available for $10 each.
Marker
light power can also be added to any DCRU: $10.00 Disadvantage is that
the lamps go off at every Reverse Button press, unlike the sound
board's marker light output, which stays on until the sound system
shuts off.
DCRU WDx comes with 4 different colors of 6-8 leads depending upon your requirements.
You can request a 2nd power lead and/or a 2nd ground lead. No additional charge.
All DCRU-WDx have F & R Directional lighting capability.
1b) Steamer DC motored Reverse units:
All
DCRU-WS come with a black 4 wire tether terminate in a 4-pin Molex plug
that is common on
MTH, Williams, Weaver and some Lionel steamers.
Note: The Lionel socket is wired differently than the other brands, which are all common.
2) Specify number of rubber tires on loco, i.e. 0, 2 or 4.
Specify if tender has a pickup roller on it.
Either of these items makes a customization necessary for satisfactory performance of your DCRU. No Charge.
The
assumption is that lack of any info means that your loco has either 0
or 2 rubber tires and the tender has no center rail pickup.
All DCRU-WSx have R Directional 1.5 Volt lighting capability.
All units Dimensions: 4.3" X 1.3" X 0.93".
UPGRADING MOTOR CURRENT CAPACITY OF YOUR DCRUs:
3a) DCRU-Wx 1/2 Hi-I Upgrade from 3.0 AMPS to 5.0 Amps DC; $15.
Has 1 Bridge Rectifier connected by 2 8" long leads for chassis mounting. Includes Mounting Hardware.
3b) DCRU-Wx Hi-I Upgrade from 3.0 Amps to 6 AMP DC: $30.
Has 2 Bridge Rectifies connected by 5 8" long leads for chassis mounting. Includes Mounting Hardware.
See Motor Current & Loads for estimating or measuring current loading.
3) Marker
light power can also be added to any DCRU: $10.00 Disadvantage is that
the lamps go off at every Reverse Button press, unlike the sound
board's marker light output, which stays on until the sound system
shuts off.
Maker Light power can be obtained from the QSI sound board.
Must use a series resistor of a least 200 Ohms to prevent micro Processor destruction.
Either Marker Light supply will power 2 LEDs.
All DCRU-WSx come with black leads and 4-pin Molex plug, mates to loco's built in Molex socket.
Gotcha!: Lionel locos built by Samhongsa have opposite polarity and reversed M/F configured Molex 4-pin plugs/sockets.
4) DC Motored Locos without socket, add 4 wire M socket to DCRU-WSx $10.00
